Yemen

A territorially divided state of roughly 37 million people on the southwestern corner of the Arabian Peninsula, governed since 2014-2015 in two parallel institutional architectures: the Houthi Supreme Political Council in Sana'a, dominated by Ansar Allah religious-political leader Abdul-Malik al-Houthi and chaired by Mahdi al-Mashat, exercising de facto authority over roughly two-thirds of the population; and the internationally recognised Presidential Leadership Council under chairman Rashad al-Alimi, operating principally from Aden and Riyadh and aligned with the Saudi-led coalition that intervened in March 2015. Five structural files define Yemen in May 2026: the post-strike degradation of Houthi military capacity following US Operation Rough Rider (March-May 2025) and the late-February 2026 US-Israeli strikes on Iran that disrupted the Iranian supply lines underpinning the Houthi missile-and-drone arsenal; the September 2025 cessation of the Houthi Red Sea shipping campaign and the cautious shipping resumption that ICG analysts have described as a "structured pause under tension"; the dramatic January 2026 collapse and dissolution of the UAE-backed Southern Transitional Council following the Saudi-aligned PLC's capture of Aden on January 7, 2026 and the dismissal of STC leader Aidarus al-Zoubaidi from the PLC on January 15, 2026; the catastrophic and worsening humanitarian situation, with 21-23.1 million people requiring humanitarian assistance in 2026 (up from 19.5 million in 2025) against a backdrop of Western donor funding cuts; and the Saudi-Houthi negotiation track via Omani mediation, with UN Special Envoy Hans Grundberg's Military Co-ordination Committee meetings continuing in Amman through April 2026.¹ What is settled in Yemen is the structural fragmentation; the Houthi consolidation of governing institutions in the north; the post-strike strategic recalculation; the collapse of the southern-separatist project as a coherent political-military force. What is not settled is whether the Saudi-Houthi negotiation produces a permanent settlement, whether Hadhramaut autonomy moves consolidate or dissipate, whether the Houthi Red Sea posture remains paused or resumes under regional escalation, whether the humanitarian funding gap closes or widens, or whether the post-Iran-strike Houthi reconstitution produces a fundamentally different post-Iran-aligned political-military trajectory.

Geography

Yemen covers approximately 455,503 square kilometres at the southwestern corner of the Arabian Peninsula, bounded by Saudi Arabia to the north along the contested 1,800-kilometre border, Oman to the east, the Gulf of Aden to the south, the Bab-el-Mandeb strait to the southwest, and the Red Sea to the west. The defining geographic facts of Yemen have shaped its strategic posture since antiquity: the Bab-el-Mandeb strait — the chokepoint between the Red Sea and the Gulf of Aden, through which approximately 12% of global maritime trade and 30% of global container traffic passed in pre-disruption normal conditions — sits at the southwestern Yemeni coast and is one of the most strategically valuable maritime passages in the world; the Red Sea coast extends approximately 450 kilometres along the western edge of the country, including the principal Houthi-controlled port of Hudaydah; the Yemeni highlands rise above 3,000 metres along the western interior, producing one of the most agriculturally rich and historically populous regions of the Arabian Peninsula; the eastern Hadhramaut governorate covers vast desert wadis and contains the country's principal oil and gas reserves; and the Socotra archipelago, a UNESCO World Heritage Site of unique biodiversity, sits in the Arabian Sea approximately 380 kilometres south of the mainland, currently under UAE military presence.

The geography drives politics in three persistent ways. First, the highland-coastal-eastern axis. The Zaidi-majority highlands have historically operated as a politically autonomous core under successive imamates; the Sunni-Shafi'i centre and south have historically aligned with coastal trading networks; the eastern Hadhramaut and Mahra regions have operated as semi-autonomous tribal-economic systems with substantial Indian Ocean diaspora connections. Second, the Bab-el-Mandeb. The strait's strategic centrality has made Yemeni territory a recurring focus of external power projection — from the Ottoman and British imperial periods through the Cold War proxy contest between the YAR and the PDRY through the post-2014 Houthi missile-and-drone campaign that disrupted global shipping. Third, the borders. The 1,800-kilometre Saudi border has been the principal external front of the post-2015 war; the Oman border has functioned as a diplomatic-mediation conduit; the Bab-el-Mandeb southern coastal frontier has been the principal locus of US, UK, and EU naval operations.

The principal cities are Sana'a (the Houthi-controlled formal capital, ~3.7 million, in the central highlands), Aden (the PLC-administered interim capital and historical British colonial port, ~1.2 million, on the southern coast), Ibb (~880,000, central highlands), Hudaydah (~620,000, Red Sea coast and the principal Houthi port for both commercial and military supplies), Ta'izz (~615,000, the third city, majority Sunni Shafi'i, contested and besieged through the war), Dhamar (~457,000, central highlands), and Mukalla (~258,000, the principal Hadhramaut city and the locus of the eastern autonomy movement).

Demographics

Yemen's population in 2026 is approximately 37 million — though estimates vary substantially given the war and the absence of recent reliable censuses, with figures ranging from 33 million to 43 million across different sources. The country is one of the youngest in the world, with a median age of approximately 20 years and a total fertility rate that has been among the highest in the Arab world. Urbanisation has reached approximately 38%, but the post-2015 conflict has driven substantial internal displacement: over 4.5 million internally displaced persons were registered as of early 2026, with approximately 400,000 Yemeni refugees abroad — primarily in Saudi Arabia, Djibouti, and Somalia.²

Ethnically, Yemen is overwhelmingly Arab (>95%), with a small but distinctive marginalised population: the Akhdam community, estimated at between 500,000 and 3.5 million (the wide range reflects the community's marginalised status in the official record), historically considered the lowest social tier in Yemeni society; the community's origins are contested — descendants of pre-Islamic Ethiopian invaders, descendants of African enslaved populations, or pre-Arab indigenous Yemenis depending on the sources — but the social marginalisation has been one of the country's most durable hierarchies. Smaller communities include South Asian labour and refugee populations and small Somali and other African-origin communities concentrated in the southern coastal cities.

Religiously, Yemen is approximately 99% Muslim, with the structural division between the Zaidi Shia community in the northern highlands (35-42%) and the Sunni Shafi'i community in the centre, south, and east (56-65%) being the foundational religious-geographic distinction of the country's political life. The Zaidi tradition is one of the principal "Fiver" Shia traditions, theologically distinct from the Twelver Shiism of Iran and Iraq and historically closer in many respects to Sunni jurisprudence. The Houthi movement (Ansar Allah) emerged from the Zaidi tradition and has produced a distinctive politicised-Zaidi religious-political ideology under Abdul-Malik al-Houthi's leadership. Smaller Ismaili Shia communities exist in the central highlands. The pre-1948 Yemeni Jewish community, once one of the oldest Jewish communities in the world, has been almost entirely emigrated; the Christian remnant is similarly small.

The tribal structure is one of Yemen's most distinctive social features. Powerful tribal confederations — the Hashid (the principal northern confederation, including the Saada-region tribes from which the Houthi movement emerged), the Bakil (the larger northern confederation extending across the central highlands), and the Madhhij (the principal southern confederation) — operate as parallel institutional structures with their own dispute-resolution, security, and political-economic functions. Tribal affiliation often supersedes state authority in practical terms; the qabyala (tribal) social system is the substrate of much of Yemeni civic life.

Generational differences are profound. The post-2014 generation — born during or shortly before the war and now in early youth — has lived its entire formative period under conflict, with substantial educational and developmental disruption. Median age remains approximately 20.2 years; pre-war Yemen is increasingly a memory carried by older Yemenis but only fragmentarily by the war-generation cohort.

History

Pre-modern Yemen and the imamate

Yemen's pre-Islamic history includes the ancient Sabaean and Himyarite kingdoms; the Queen of Sheba in Biblical and Quranic tradition is associated with Yemeni civilisation. The Islamic conquest of the 7th century CE brought both Sunni and Shia traditions to the country. The Zaidi imamate was established in approximately 897 CE by Imam al-Hadi ila al-Haqq Yahya, founding a religious-political tradition that — with substantial interruptions and territorial variation — ruled over the northern highlands for over a thousand years. Imam Yahya consolidated power in the early 20th century after the dissolution of the Ottoman position in Yemen; his son Imam Ahmad ruled from 1948 to 1962. The British colonisation of Aden began in 1839 and produced the Aden Protectorate over the southern hinterlands, separating the southern political trajectory from the northern imamate by over a century.

The two Yemens and the 1990 unification

The September 26, 1962 republican revolution under military officers led by Abdullah al-Sallal deposed the newly enthroned Imam Muhammad al-Badr and proclaimed the Yemen Arab Republic (YAR, North Yemen). The subsequent civil war, fought between the Egyptian-backed republicans and the Saudi-backed royalists, ended in 1970 with a republican victory and royalist accommodation. The British departure from Aden in 1967 produced the People's Democratic Republic of Yemen (PDRY, South Yemen), which adopted a Marxist-Leninist political system in 1970 — the only Marxist state in the Arab world. The May 22, 1990 unification of the YAR (under Ali Abdullah Saleh) and the PDRY (under Ali Salem al-Beidh) produced the modern Republic of Yemen. The 1994 civil war — a southern secession attempt crushed by Saleh's northern-dominated military — preserved unity but established the structural southern grievance that has resurfaced repeatedly since.

The Sa'dah wars and the 2011 uprising

The 2004-2010 Sa'dah wars between the Saleh government and the Houthi movement (Ansar Allah, named after the early Islamic "Helpers" who supported the Prophet in Medina) — six rounds of conflict in the Sa'dah governorate, rooted in Zaidi marginalisation under Saleh's increasingly Sunni-Islamist political alliances — produced the structural conditions for the post-2014 Houthi takeover. The 2011 Arab Spring uprising forced Saleh's resignation; he transferred power in 2012 to Vice President Abdrabbuh Mansur Hadi via a GCC-brokered transition. The post-2011 transitional period produced the National Dialogue Conference (2013-2014), which generated extensive political-reform proposals that were never substantially implemented before the September 2014 Houthi seizure of Sana'a.

The 2014-2015 takeover and the Saudi-led intervention

Houthi forces, in alliance with Saleh-loyalist military units, seized Sana'a in September 2014 and advanced south through 2014-2015, capturing the strategic city of Ta'izz and threatening Aden. President Hadi fled first to Aden and then, in February-March 2015, to Saudi Arabia. Saudi Arabia launched Operation Decisive Storm on March 26, 2015, with a coalition that included the United Arab Emirates, Bahrain, Kuwait, Qatar (until the 2017 Gulf rift), Egypt, Sudan, Jordan, and Morocco, and US, UK, and French logistical and intelligence support. The Saudi-led campaign — substantially an air operation in its initial phases — failed to dislodge the Houthis from Sana'a despite extensive bombardment that produced widely documented civilian casualties and the long-term humanitarian crisis. The 2017 killing of Saleh by his former Houthi allies after a public break consolidated Houthi political control of the north.

Post-2022 architecture and the Houthi Red Sea campaign

The April 2022 GCC-brokered transition to the Presidential Leadership Council under Rashad al-Alimi was paired with the UN-brokered April-October 2022 truce, which produced the longest sustained period of relative quiet in the conflict. Although the formal truce expired in October 2022, an informal ceasefire substantially held through 2023. The October 7, 2023 Hamas attack and the subsequent Israeli operations in Gaza produced the structural shift: from October 2023, the Houthis launched an unprecedented missile-and-drone campaign against Israeli targets and Red Sea shipping, framing the campaign as solidarity with the Palestinians of Gaza. The campaign disrupted global trade — Suez Canal traffic dropped substantially as shipping rerouted around the Cape of Good Hope — and produced US-led Operation Prosperity Guardian (December 2023) and the more intensive US Operation Rough Rider (March-May 2025), which significantly degraded Houthi infrastructure. The Houthi Red Sea attacks ceased in September 2025 after the cumulative degradation effect.³

The 2024-2026 most recent events

December 2024 produced the Assad collapse in Syria, with downstream regional implications for the Iranian-aligned axis. February 28, 2026 marked the onset of the US-Israeli strikes on Iran that further disrupted Houthi supply lines. December 2025 to January 2026 produced the dramatic STC episode: STC forces under Aidarus al-Zoubaidi attempted to seize Hadhramaut and al-Mahra, were defeated by the Saudi-backed PLC counteroffensive, and lost Aden to the PLC on January 7, 2026. The STC announced its dissolution; al-Alimi dismissed Zoubaidi and STC vice-chairman Faraj Al-Bahsani from the PLC on January 15, 2026. New PM Shaya Mohsen al-Zindani formed a 34-member cabinet on February 6, 2026. On February 28, 2026 the PLC issued a public warning to the Houthis against entering the regional escalation around the Iran war.⁴

Political system

Yemen in 2026 operates under two parallel institutional architectures with no single central authority — the structural feature that distinguishes it from every other state in the region.

The Houthi-controlled north

The Supreme Political Council is the de facto government of the territory under Houthi control, including Sana'a, Hudaydah, Sa'dah, Dhamar, Ibb, and surrounding governorates. Mahdi al-Mashat has served as president of the SPC since 2018 and is the day-to-day governance authority; he was born in 1986 and has a generational profile substantially younger than most regional leaders. The principal religious-political authority above the SPC is Abdul-Malik al-Houthi, the leader of Ansar Allah and the structural authority on strategic decisions; he rarely appears publicly and directs strategy through recorded video and audio addresses. The Houthi parallel state has, over more than a decade of consolidation, developed substantial governing institutions: parallel courts, a taxation system, internal security forces, education and health bureaucracies, and a state media apparatus. The institutional density of Houthi governance is one of the underappreciated structural features of the contemporary Yemeni state architecture.

The Presidential Leadership Council in Aden

The Presidential Leadership Council is the internationally recognised government, established in April 2022 when President Hadi transferred his executive authority to the eight-member council under chairman Rashad al-Alimi. The PLC operates principally from Aden (when security conditions permit) and Riyadh (where most members reside under Saudi protection). Following the January 15, 2026 dismissal of Zoubaidi and Al-Bahsani, the PLC composition includes:

• Rashad al-Alimi (chairman)
• Sultan Al-Aradah (former Marib governor)
• Dr. Abdullah Al-Alimi (no relation to the chairman)
• Salem Al-Khanbashi
• Tareq Saleh (the principal western-coast forces commander; nephew of the late President Ali Abdullah Saleh)
• Othman Mujalli
• Mahmoud Al-Subaihi
• Abdulrahman Al-Muharrami (replacing Zoubaidi from January 15, 2026)

Prime Minister Shaya Mohsen al-Zindani has headed the cabinet of the internationally recognised government since February 2026, succeeding Ahmad Awad bin Mubarak. The 34-member cabinet formed on February 6, 2026 reflects the post-STC political consolidation under Saudi backing.⁵

The Southern Transitional Council and its January 2026 collapse

The Southern Transitional Council, founded in 2017 with UAE backing, pursued southern independence and operated parallel security forces (the UAE-funded Security Belt Forces) across much of the south through the late 2010s and early 2020s. Council leader Aidarus al-Zoubaidi announced a "transitional phase" toward southern self-determination on January 1, 2026; STC forces moved to seize Hadhramaut and al-Mahra in December 2025. The Saudi-backed PLC counteroffensive defeated the STC militarily, captured Aden on January 7, 2026, and forced Zoubaidi to flee to the UAE. The STC announced its dissolution as a political organisation; the Saudi airstrikes on STC positions during the January 2026 fighting marked the most explicit Saudi-UAE bilateral rift over Yemen since the 2015 coalition formation. The southern-separatist political project has not disappeared — Hadhramaut autonomy moves continue, and underlying southern grievance is structural — but the organised political-military force has been substantially eliminated.⁶

Civil-military relations and the broader security architecture

Yemen's military structures are fragmented across five principal categories: the Houthi armed forces and Houthi-aligned militias (the dominant force in the north); the PLC-aligned units (Saudi-funded, including the National Resistance under Tareq Saleh on the western coast and the various Saudi-trained brigades); the formerly UAE-funded Security Belt Forces and Hadhrami Elite Forces (substantially collapsed after January 2026); the tribal militias of the major confederations; and the surviving al-Qaeda in the Arabian Peninsula (AQAP) presence in parts of the central and eastern provinces. The fragmentation is structural; there is no plausible path to a unified Yemeni military in the medium term.

Economy

Yemen's economy in 2026 has been described by the World Bank as "collapsed." Negative GDP growth, a Yemeni rial in free-fall (with a structurally divergent exchange rate between Houthi-issued and Aden-issued notes producing a de facto dual-currency system), and over 80% of the population below the poverty line define the macroeconomic profile. The pre-2015 economic structure — substantially based on oil and gas exports from Hadhramaut and Marib, with remittances from the Yemeni diaspora in Saudi Arabia and the Gulf as a major secondary input — has been comprehensively disrupted.⁷

The dual-currency system is one of the war's most consequential economic-institutional fragmentations. The Central Bank of Yemen, formally headquartered in Aden under the internationally recognised government, issues notes that circulate in PLC-controlled territory; the Houthi-administered Central Bank in Sana'a issues separate notes that circulate in Houthi-controlled territory. The exchange-rate divergence between the two has produced effectively two separate currencies and substantially complicated trade between the two zones.

The humanitarian situation is the dominant economic-political fact. The UN OCHA 2026 Humanitarian Needs and Response Plan identified 21-23.1 million Yemenis requiring humanitarian assistance — up from 19.5 million in 2025. Approximately 18 million face food insecurity. Cumulative deaths since 2015 have exceeded 377,000, with approximately 60% of those deaths attributed to hunger and disease rather than direct combat. Cholera, dengue, and malaria outbreaks recur. Only approximately half of health facilities are operational. Western donor funding cuts in 2026 — driven by the broader retrenchment of US and European international-development budgets — threaten to reverse the modest improvements in malnutrition and basic-health indicators that humanitarian operations had achieved in 2024-2025.⁸

The oil and gas sector is largely dormant. Marib (PLC-controlled) and Hadhramaut hold the principal reserves, but production has been minimal since 2015; the Houthi blockade of southern oil exports has further constrained PLC revenue. Pre-war Yemen exported approximately 200,000-300,000 barrels per day of crude; current export volumes are a fraction of that. The contested governance of any post-conflict oil-revenue arrangement is one of the principal questions in the Saudi-Houthi negotiation track.

Remittances from the Yemeni diaspora in Saudi Arabia and the broader Gulf remain a critical source of foreign-currency inflow at the household level. Exact figures are difficult given the institutional fragmentation, but remittances are widely understood to be one of the largest components of Yemen's foreign-currency receipts in 2026.

The structural economic question is whether the post-strike negotiated settlement framework — if Saudi-Houthi talks produce a durable arrangement — can support the gradual reconstitution of basic state functions, the rehabilitation of oil and gas exports, and the resumption of the Hudaydah-Sana'a-Aden trade architecture. The alternative — a frozen-conflict economic-institutional fragmentation persisting into the late 2020s — is the more likely path on current evidence, though external developments (Saudi fiscal posture, US humanitarian-aid policy, Iranian post-strike trajectory) could substantially shift the probability distribution.

Foreign policy

Yemeni foreign policy in 2026 operates as two parallel files: the Houthi external posture and the PLC external posture. The two sets of relationships are substantially distinct.

The Houthi Red Sea campaign and post-strike degradation

The October 2023-September 2025 Red Sea campaign was the most consequential Houthi external operation in the movement's history. Following October 7, 2023, the Houthis launched missile and drone attacks against Israeli territory and against commercial shipping transiting the Bab-el-Mandeb and the southern Red Sea, framing the campaign as solidarity with Gaza. The campaign disrupted approximately 80% of normal Bab-el-Mandeb container traffic at peak; major shipping lines (Maersk, MSC, CMA CGM, Hapag-Lloyd) suspended Red Sea routing and rerouted around the Cape of Good Hope. US Operation Prosperity Guardian (December 2023 onward) provided naval escort and limited strikes; US Operation Rough Rider (March-May 2025) was a substantially more intensive air campaign that targeted Houthi radars, launch sites, supply lines along the Sana'a-Hudaydah axis, command centres, and economic infrastructure, producing over $1 billion in assessed damage. The Houthi attacks ceased in September 2025 after cumulative degradation. Cautious shipping resumption has occurred since September 2025, but ICG and other analysts have characterised the resumption as a "structured pause under tension" rather than a permanent settlement, with shipping insurance rates remaining elevated and some vessels still rerouting around Africa.⁹

The late-February 2026 US-Israeli strikes on Iran further degraded the Iranian supply lines that had underpinned the Houthi missile-and-drone arsenal through the Iran-aligned smuggling routes through the Red Sea and the Arabian Sea. Abdul-Malik al-Houthi declared support for Iran on March 5, 2026, and the Houthis conducted limited supportive strikes during the March 2026 escalation, but at intensities far below the 2024-2025 peak. ISW analysts assessed in April 2026 that the Houthis are "weighing whether to deplete reserves that they cannot replenish" given the disrupted supply lines, suggesting a "conditional deterrence posture" rather than incapacity.¹⁰

The Saudi-Houthi negotiation track and Omani mediation

Saudi-Houthi talks have continued through 2024-2026 under primary Omani mediation, with the UN Special Envoy Hans Grundberg facilitating broader institutional engagement. The April 21-22, 2026 Amman meetings of the UN Military Co-ordination Committee with Saudi and Houthi representatives represented the most substantive recent diplomatic engagement. Houthi SPC president Mahdi al-Mashat warned Saudi Arabia on March 25, 2026 that "our people cannot be patient indefinitely" and demanded implementation of "roadmap" commitments including salary payments to Yemeni public-sector workers from oil-revenue proceeds. The substantive question is whether the post-strike Iranian degradation enables the negotiation to converge — by reducing the Houthi alternative-deterrence value to Iran and increasing Houthi incentives for a durable Saudi accommodation — or whether the Houthis use any future regional escalation as leverage.¹¹

The post-January 2026 Saudi-UAE rift over Yemen

The January 2026 Saudi airstrikes on STC positions and the dissolution of the STC marked the most explicit Saudi-UAE bilateral rift over Yemen since the 2015 coalition formation. UAE influence in southern Yemen has been substantially reduced; the UAE retains its Socotra military presence but its prior role through the STC and the Security Belt Forces has been substantially eliminated. The rift is partial — Saudi Arabia and the UAE retain extensive cooperation across other regional files — but the Yemen-specific divergence is a structural feature of 2026.

The PLC posture toward Iran, Israel, and the broader region

The PLC has held a posture of opposition to the Houthi and Iranian alignment, support for the broader Saudi-led Sunni Arab regional architecture, and cautious engagement with Israel and the post-strike regional reordering. The February 28, 2026 PLC warning to the Houthis against involvement in the Iran war was the principal recent expression of the PLC's strategic positioning. The PLC has cooperated with US, UK, and EU naval operations in the Red Sea and has supported the broader anti-Houthi diplomatic posture.

The post-Assad Syria implication

The December 2024 Assad collapse and the establishment of the Turkey-aligned al-Sharaa transitional government in Damascus has substantially changed the Iran-aligned regional axis of which the Houthis were a significant component. The Houthi-Syria relationship was always limited (the geographic separation produced little direct bilateral substance), but the broader Iranian regional network reduction has structural implications for the Houthi strategic calculation.

Allies and rivals

Characterisation of the principal relationships in one line each.

• Iran — Principal Houthi backer through 2025 (weapons, training, funding via smuggling routes); structural rival of the PLC; the post-February 2026 strikes have substantially degraded the Iran-Houthi supply architecture.
• Saudi Arabia — Leads anti-Houthi coalition since 2015; principal PLC backer; negotiating with Houthis via Oman; defeated UAE-backed STC in January 2026; the dominant external power in Yemen as of May 2026.
• United Arab Emirates — Formerly the principal STC backer; rift with Saudi Arabia after January 2026 STC collapse; retains Socotra military presence; substantially reduced political role in mainland Yemen.
• United States — Conducts strikes against Houthis (Operation Prosperity Guardian and Operation Rough Rider); supports PLC; provides intelligence and logistics to the Saudi coalition; the principal external strike actor against the Houthis.
• United Kingdom — Partners with US in anti-Houthi naval and air operations since December 2023.
• Egypt — Concerned about Red Sea security and the Houthi threat to Suez Canal traffic; supports PLC; Suez Canal revenue recovery in 2026 is partly contingent on continuing Houthi de-escalation.
• Israel — Target of Houthi missile-and-drone attacks October 2023-March 2026; conducted limited strikes on Houthi infrastructure; the post-strike regional reordering has reshaped this file.
• Oman — Neutral mediator between Saudi Arabia and the Houthis since 2021; hosts talks; maintains relations with all parties; the principal regional diplomatic broker.
• Post-Assad Syria — Minimal direct relationship; geographic separation; the shift to the Turkey-aligned al-Sharaa government further reduces Yemen-Syria substantive ties.
• EU — Coordinates Red Sea maritime security through Operation Aspides (February 2024); concerned about trade disruption; cooperates with PLC on humanitarian and political files.
• China — Limited direct role; some Belt and Road infrastructure interest in pre-war period; constrained by the security situation.
• Russia — Limited direct role; engages diplomatically through the UN Security Council file.

Key figures

Abdul-Malik al-Houthi (عبد الملك الحوثي), born 1979 in Sa'dah. The leader of Ansar Allah (the Houthi movement) and the principal religious-political authority in northern Yemen since the 2004 death of his brother Hussein al-Houthi (the movement's founder). Rarely appears publicly; directs strategy through recorded video and audio addresses. The architect of the Houthi state-building project, the Red Sea campaign, and the broader Iranian-axis alignment. The structural authority above the formal SPC.¹²

Mahdi al-Mashat (مهدي المشاط), born 1986. President of the Houthi Supreme Political Council since 2018. The day-to-day governance leader of the Houthi-controlled state; the principal public-facing figure of the Houthi political institutions. His warning to Saudi Arabia on March 25, 2026 demanding implementation of "roadmap" commitments was the principal recent SPC public statement on the negotiation track.

Rashad al-Alimi (رشاد العليمي), born 1954. Chairman of the Presidential Leadership Council since April 2022. Former interior minister under the Saleh government; the principal political figure of the internationally recognised state. The architect of the post-2022 PLC consolidation and the January 15, 2026 dismissal of the STC members from the council.

Aidarus al-Zoubaidi (عيدروس الزُبيدي), born 1967. Former chairman of the Southern Transitional Council; former PLC member; military commander before his political career. The principal southern-separatist leader through 2017-2026; announced the southern "transitional phase" on January 1, 2026; defeated by PLC forces in January 2026 and dismissed from the PLC on January 15, 2026; now in UAE exile. The future political role of Zoubaidi remains an open question.

Tareq Saleh (طارق صالح), born 1971. PLC member; commander of the National Resistance forces on the western coast; nephew of late President Ali Abdullah Saleh. The principal Saleh-family political-military figure remaining in Yemen. His political-military weight in the western-coast areas is structural.

Shaya Mohsen al-Zindani (شايع محسن الزنداني), Prime Minister of the internationally recognised government since February 2026. Formed the 34-member cabinet on February 6, 2026 succeeding Ahmad Awad bin Mubarak. The principal post-STC-defeat civilian-administrative figure of the PLC's reorganisation.

Mohammed Ali al-Houthi (محمد علي الحوثي), Head of the Houthi Supreme Revolutionary Committee. A senior Houthi political figure with public profile; principal political-rhetorical voice of the Houthi state.

Hans Grundberg (the United Nations Special Envoy for Yemen since September 2021). The principal international diplomatic mediator; convenes the Military Co-ordination Committee meetings in Amman and broader institutional engagement.

Abdrabbuh Mansur Hadi (عبد ربه منصور هادي), former president 2012-2022; in Saudi exile. Ceded executive authority to the PLC in April 2022 but remains a symbolic figure of the post-2011 transition.

Internal regions and subcultures

Yemen's internal map is shaped by the highland-coastal-eastern geography, the post-1990 unification's incomplete integration, and the post-2014 territorial fragmentation. The cultural-political variations are substantial.

Sa'dah and the Houthi heartland. The northwestern governorate bordering Saudi Arabia; the Houthi movement's birthplace; heavily Zaidi; the site of the 2004-2010 Sa'dah wars. The region has been deeply scarred by conflict and Saudi airstrikes; the Houthi institutional and ideological consolidation has been densest here.

Sana'a. The historical capital, with a population of approximately 3.7 million. Houthi-controlled since September 2014. Mixed Zaidi-Sunni population. The UNESCO World Heritage Old City of Sana'a — with its distinctive multi-storey mud-and-burnt-brick towers — is one of the most architecturally distinctive urban sites in the world. The political and cultural centre of the country.

Ta'izz. Yemen's third-largest city (~615,000); majority Sunni Shafi'i; contested between Houthi forces and government-aligned militias since 2015. The siege of Ta'izz produced massive humanitarian suffering; the city has been one of the most fiercely contested in the war and has produced one of the most distinctive Sunni-Shafi'i resistance political identities to Houthi control.

Aden and the southern coastal areas. The historical British colonial capital; the interim seat of the internationally recognised government. Captured by the PLC from the STC on January 7, 2026. Population ~1.2 million. The port economy and the distinct southern political identity (rooted in the PDRY period and the 1994 civil-war grievance) shape the city's contemporary politics.

Hadhramaut. The vast southeastern governorate; capital Mukalla (~258,000). Holds Yemen's principal oil and gas reserves. Distinct Hadrami culture, including substantial Indian Ocean diaspora connections to East Africa, India, Indonesia, and East Timor. Autonomy movement persistent. Contested between PLC and STC December 2025-January 2026; the post-STC-defeat trajectory has reduced separatist organisational capacity but the autonomy aspiration remains structural.

Marib. The central-eastern governorate; oil and gas resources; PLC-controlled; the principal frontline province with Houthi forces. The population has swelled with internally displaced persons; the strategic energy hub status makes the province one of the most contested in any future settlement.

Socotra. The remote Arabian Sea archipelago; unique biodiversity (UNESCO World Heritage Site); UAE military presence; population approximately 60,000; distinct Soqotri language and culture, predating the Arab Islamic mainland. The UAE presence has been a recurring source of political tension.

Mahra. The far-eastern governorate bordering Oman; distinct Mahri language and culture; sparse population. Contested between the PLC and the STC during the January 2026 fighting.

Tribal confederations. The Hashid (the principal northern confederation, including the Houthi-affiliated Saada-region tribes), the Bakil (the larger northern confederation), and the Madhhij (the principal southern confederation) operate as parallel institutional structures with their own dispute-resolution, security, and political-economic functions. Tribal affiliation often supersedes state authority; the qabyala social system is the substrate of much of Yemeni civic life.

The Akhdam community. The marginalised group historically considered the lowest tier of Yemeni society. Estimated at 500,000 to 3.5 million (the wide range reflects the community's marginalisation in the official record). Concentrated in urban slums; faces severe discrimination; works in menial occupations. The community's origins are contested but the social marginalisation has been one of the country's most durable hierarchies.

Cultural concepts

Hijra (هجرة) — in the Yemeni Zaidi political-religious context, the fortified settlements where Zaidi imams and sayyids (descendants of the Prophet Muhammad) historically lived, maintaining religious scholarship and armed protection. The Houthi movement is rooted in hijra traditions; the political-religious authority of the sayyid class in Zaidi political theology is structurally distinct from the broader Sunni-majority Arab world.

Ahl al-Bayt (أهل البيت, People of the House) — the family of the Prophet Muhammad. Central to Zaidi ideology; Houthi legitimacy claims rest substantially on the Ahl al-Bayt descent of the Houthi family. The emphasis on leadership by the Prophet's descendants shapes the Zaidi-distinctive political theology.

Sayyid (سيد, plural sada) — the descendants of the Prophet Muhammad through his grandson Hasan. A privileged caste in Zaidi society; the Houthi leaders are sada from the Hashemite Banu Hashim clan. The Yemeni social hierarchy historically placed sada above qabilis (tribesmen), with Akhdam at the bottom — a structural feature of pre-modern Yemeni society that has been politicised differently by different post-1962 political projects.

Ansar Allah (أنصار الله, Supporters of God) — the official name of the Houthi movement. Evokes the early Islamic Ansar (the "Helpers" who supported the Prophet Muhammad in Medina). Frames the movement as defending true Islam against external enemies; the political-rhetorical weight of the name is structural to Houthi identity.

Qabili (قبيلي, plural qabā'il) — tribesman; a member of a recognised tribe with genealogy, honour code, and arms-bearing tradition. Distinct from non-tribal populations; central to the Yemeni social-identity vocabulary.

Qabyala (قبيلة) — tribe; the fundamental social-political unit. Provides protection, dispute resolution, and collective identity. Tribal law (urf) often supersedes state law in practical terms; the qabyala-dawla (state) tension is one of the country's structural political-cultural fault lines.

Asabiyya (عصبية) — group solidarity and cohesion; Ibn Khaldun's concept of the social bonds that enable political power. Tribes maintain strong asabiyya at the sub-state level; the fragmentation of national asabiyya across the post-1962 republican project is one of the structural-historical conditions of the post-2014 fragmentation.

Qat (قات) — the mildly narcotic leaf chewed daily by the majority of Yemeni men (and a smaller share of women). Afternoon qat-chewing sessions are the principal social institution for networking, dispute resolution, and political discussion. The qat economy consumes approximately 40% of agricultural water; the social-economic centrality is structural and one of the country's most distinctive cultural features.

Bayt (بيت, house / household) — the extended family/household unit; the fundamental economic-social structure. Buyut (the plural) within tribes form alliances; the reputation of one's bayt shapes social standing.

Wasta (واسطة) — personal connections and intercession. Like in much of the Arab world, wasta is the routine informal mechanism for navigating bureaucracy, business, and security. The institutionalisation of wasta in lieu of (or alongside) formal state institutions is a structural feature of Yemeni civic life.

Current situation

As of May 2026, Yemen sits at the convergence of multiple structural transitions, with six files driving the country's politics.

The first is the post-strike Houthi capacity recalculation. The cumulative US Operation Rough Rider damage of 2025 and the late-February 2026 US-Israeli strikes on Iran have substantially degraded the Houthi missile-and-drone arsenal and the supply lines that produce it. The September 2025 cessation of Red Sea attacks and the limited March 2026 supportive strikes during the Iran escalation reflect a "conditional deterrence posture" — the Houthis retain substantial reserves but are weighing the cost of depletion against the value of escalation. Whether the Houthi reconstitution can occur under a substantially weakened Iran is the principal medium-term question.

The second is the Saudi-Houthi negotiation track. Omani-mediated talks and the UN Military Co-ordination Committee under Hans Grundberg continue through 2026. The post-strike Iranian degradation may improve the negotiation conditions by reducing the Houthi alternative-deterrence value to Iran. The substantive question is whether a durable settlement is achievable, including the contested oil-revenue arrangement and the structural political-economic accommodation between the Houthi north and the PLC-administered areas.

The third is the post-STC southern political reorganisation. The January 2026 STC defeat and dissolution has substantially eliminated the organised southern-separatist political-military force. The Saudi-aligned PLC has consolidated control of the south. The southern-separatist political project has not disappeared — Hadhramaut autonomy moves persist, and underlying southern grievance is structural — but the organised force has been substantially eliminated for the medium term.

The fourth is the humanitarian and economic situation. The 21-23.1 million Yemenis requiring humanitarian assistance in 2026, the 18 million food insecure, the over 80% poverty rate, the dual-currency system, the collapsed health and education infrastructure — all indicators are deteriorating, not improving. Western donor funding cuts in 2026 threaten to reverse modest 2024-2025 gains. Yemen remains "one of the world's worst humanitarian crises" by UN OCHA characterisation.

The fifth is the Red Sea shipping resumption and its conditional fragility. Cautious shipping resumption since September 2025 reflects "structured pause under tension" rather than permanent settlement. If US-Iran tensions spike or Israeli-Iranian confrontation escalates, the Red Sea re-emerges as a "low-cost, high-visibility response domain" for Houthis. Insurance rates remain elevated; some vessels still reroute around the Cape of Good Hope.

The sixth is the post-Iran-strike regional reordering implications. The disruption of Iranian supply lines forces Houthi strategic recalculation. The Saudi-Houthi talks may benefit from Iran's weakened position. But the fragile ceasefire remains vulnerable to Iran using the Houthis as a pressure point if regional tensions escalate. Whether the Iranian post-strike trajectory produces a stabilised regional architecture or a renewed escalation cycle is the principal external variable.

What is settled by May 2026: the Houthi consolidation of governance in the north; the PLC consolidation under Saudi backing; the STC organisational collapse; the post-strike degradation of Houthi-Iranian supply architecture; the September 2025 Red Sea shipping pause. What is not settled: the durability of the Saudi-Houthi negotiation; the structural disposition of Hadhramaut autonomy; the resumption-or-permanence of the Red Sea pause; the closure-or-widening of the humanitarian funding gap; the trajectory of the broader Iranian regional architecture and its implications for the Houthi strategic posture.
