Yemen

Yemen is a country at the southern end of the Arabian Peninsula, bordering Saudi Arabia and Oman and facing the Red Sea, Gulf of Aden and Arabian Sea. Its territory includes high mountain ranges, plateaus, coastal plains and desert. Sanaa is the capital, while Aden is a major port. Yemen’s position near the Bab-el-Mandeb Strait places it beside one of the world’s principal maritime routes.

The modern Republic of Yemen was formed in 1990 through the unification of the Yemen Arab Republic in the north and the People’s Democratic Republic of Yemen in the south. Political disputes and armed conflict have repeatedly challenged the unity of the state. Since 2014, the Houthi movement has controlled Sanaa and much of the north, while the internationally recognized government and other forces have held areas elsewhere. Regional intervention and economic collapse have created a severe humanitarian crisis.

Yemeni society is predominantly Arab and Muslim, with distinct regional, tribal and linguistic traditions. Arabic is the official language, and local dialects vary between highlands, coasts and eastern regions. The economy has relied on agriculture, trade, remittances and oil exports, but conflict has damaged infrastructure and public services. Poverty, food insecurity and water scarcity remain among the country’s most urgent challenges.

Etymology

The name Yemen is traditionally associated with Arabic words for the south or the right-hand side, reflecting the peninsula’s location from the perspective of people facing east. Ancient Greek and Roman sources used names such as Arabia Felix for the fertile southern region, in contrast with desert areas farther north. The modern Arabic name is al-Yaman.

Before unification, the terms North Yemen and South Yemen were used for two separate states. Their official names were the Yemen Arab Republic and the People’s Democratic Republic of Yemen. After the 1990 union, the state took the name Republic of Yemen. These political names reflect the modern division and reunification of the country, while the broader geographic term Yemen has a much older history.

History

Ancient kingdoms and trade

Ancient Yemen contained prosperous kingdoms including Saba, Qataban, Hadramaut and Himyar. Their societies developed irrigation systems, monumental architecture and written languages. The Ma'rib Dam supported agriculture in the Sabaean kingdom and is remembered as one of the region’s great engineering works. Southern Arabia’s frankincense and myrrh trade connected the Mediterranean world with East Africa and India. Caravans transported aromatics and other goods through desert routes to Mediterranean markets.

The kingdom of Himyar became a major power in the late ancient period. Yemen’s rulers interacted with the Roman and Persian empires and with Christian communities in Ethiopia and the Levant. In the sixth century, Ethiopian forces intervened in Yemen, followed by Persian rule. The region’s strategic location and commercial wealth attracted external powers, while local dynasties retained influence in highland and coastal areas.

Islamic era and Portuguese rivalry

Yemen entered the Muslim world in the seventh century, and its ports and highlands became part of successive caliphates and regional dynasties. The Zaydi tradition established a durable political and religious presence in the northern highlands. Coastal regions, including Aden, were integrated into Indian Ocean trade networks. Yemen’s terrain allowed local rulers and imams to maintain authority despite changes in distant capitals.

Ottoman forces sought control of the northern highlands and Red Sea coast in several periods, while the Portuguese attempted to dominate maritime routes in the sixteenth century. Aden’s harbour was strategically important for controlling traffic between the Red Sea and Indian Ocean. Ottoman rule was contested by local Zaydi imams and tribal leaders. Political authority remained fragmented, with distinct regional centres and shifting alliances.

Modern era and division

In the nineteenth century, Britain occupied Aden in 1839 to secure a port on the route to India. British influence expanded through treaties with rulers of the southern hinterland, which became the Aden Protectorate. The Ottoman Empire re-established authority over northern Yemen and held it until the First World War. After the Ottoman withdrawal, Imam Yahya founded the Mutawakkilite Kingdom of Yemen, which remained isolated and conservative.

In 1962, army officers overthrew the monarchy and proclaimed the Yemen Arab Republic. A civil war followed between republican forces, supported by Egypt, and royalists backed by Saudi Arabia and Jordan. The conflict ended in 1970, though political instability persisted. In the south, the Aden Emergency ended British rule in 1967 and established the People’s Republic of South Yemen, later renamed the People’s Democratic Republic of Yemen. The southern state adopted a socialist system and maintained ties with the Soviet bloc.

North and South Yemen fought in 1972 and 1979, but negotiations continued toward unification. On 22 May 1990, the two states joined to form the Republic of Yemen. Ali Abdullah Saleh, president of the north, became president of the unified country, while southern leader Ali Salim al-Beidh became vice president. Disagreements over power-sharing and resource distribution led to a southern secession attempt and civil war in 1994. Northern forces defeated the southern government, centralizing authority in Sanaa.

Protests, political transition and civil war

Protests in 2011, during the Arab Spring, called for Saleh’s resignation after decades in power. Gulf-mediated negotiations transferred the presidency to Vice President Abdrabbuh Mansur Hadi in 2012. A national dialogue sought to address constitutional reform, federalism and regional representation. The process did not resolve disputes over power and territory. The Houthi movement, rooted in the Zaydi highlands, expanded its influence and entered Sanaa in 2014.

In 2015, a coalition led by Saudi Arabia intervened militarily in support of Hadi’s government. The conflict involved the Houthis, government forces, southern separatists, tribal groups and extremist organizations. Iran has supported the Houthi movement, while the Saudi-led coalition received support from several Western states. Airstrikes, ground fighting, blockade restrictions and attacks on infrastructure caused civilian deaths and widespread displacement. Al-Qaeda in the Arabian Peninsula and Islamic State also conducted attacks.

The Houthis consolidated control over Sanaa and much of the northwest, while the internationally recognized government operated from other locations and received support from Saudi Arabia. Southern separatists associated with the Southern Transitional Council gained influence in Aden and other southern areas. The conflict fragmented state institutions and divided the security forces. A 2018 agreement sought to reduce fighting around the port city of Hodeidah, a lifeline for food and humanitarian supplies.

A United Nations-brokered truce in 2022 reduced cross-border attacks and major fighting for a period, though the conflict was not formally resolved. The parties exchanged prisoners and discussed salary payments and reopening roads. In late 2023, Houthi attacks on commercial shipping in the Red Sea and Gulf of Aden prompted U.S. and British strikes against Houthi targets. The group said its actions were linked to the war in Gaza; the attacks disrupted shipping and drew wider international involvement. Yemen’s political settlement remains uncertain, with multiple authorities controlling territory.

Geography

Yemen lies at the southwestern corner of the Arabian Peninsula. The Red Sea forms its western coast, the Gulf of Aden its southern coast, and the Arabian Sea its southeastern coast. The highlands rise sharply inland from the coastal Tihama plain. The western mountains include Jabal an-Nabi Shu'ayb, the highest peak on the peninsula. The eastern plateau descends toward the Rub' al Khali desert.

Yemen’s strategic position beside the Bab-el-Mandeb Strait connects the Red Sea with the Gulf of Aden and Indian Ocean. The island of Socotra lies in the Arabian Sea and supports distinctive ecosystems. Aden is a natural harbour and has served as a commercial and naval port. Aden remains an important southern urban centre, while Sanaa is a highland city with a historic old town.

Regions, climate and biodiversity

Climate varies by elevation and region. The Tihama coast is hot and humid, the highlands are cooler and receive seasonal rainfall, and eastern regions are arid. Summer monsoon rains reach parts of the south and east. Water availability depends on rainfall, wells and seasonal streams. Drought and groundwater depletion have intensified pressure on agriculture and cities.

Yemen contains mountain forests, coastal wetlands, desert habitats and marine ecosystems. Socotra is known for endemic plant species, including the dragon’s blood tree. The Red Sea and Arabian Sea support coral reefs, fisheries and migratory species. Habitat loss, overgrazing, charcoal production and conflict threaten biodiversity. Conservation efforts have been limited by insecurity and economic collapse.

Government and politics

Yemen’s constitution establishes a republic with an elected president and parliament, but political authority has been divided since the civil war began. The internationally recognized government operates through a Presidential Leadership Council formed in 2022. The Houthi movement administers areas under its control from Sanaa. Southern separatist institutions and local authorities also exercise power. The fragmentation limits national law, services and public accountability.

Administration, foreign relations and military

Yemen is divided into governorates, districts and subdistricts. Sanaa and Aden have special administrative status. Control of governorates has shifted during the conflict, and different authorities appoint officials and collect revenue. Local councils and tribal leaders remain important in resolving disputes and providing services, especially where national institutions are absent.

Foreign relations are shaped by the conflict and Yemen’s strategic location. Saudi Arabia has led the coalition supporting the recognized government, while Iran has provided political and material support to the Houthis. Oman has served as a mediator and maintains channels to several parties. The United States and Britain have conducted strikes in response to Houthi maritime attacks. The United Nations has led negotiations and humanitarian coordination.

Yemen’s armed forces fractured after 2011. Forces aligned with the recognized government include units supported by Saudi Arabia and the United Arab Emirates. Houthi forces control the capital and much of the north. Southern Transitional Council forces hold positions in parts of the south. Tribal militias and extremist groups have further fragmented security. Any settlement would need to address command structures, weapons, integration and regional guarantees.

Human rights

All major parties have been accused of serious human-rights abuses. These include indiscriminate attacks, arbitrary detention, torture, recruitment of children, restrictions on aid and attacks on journalists. Land mines and unexploded ordnance continue to threaten civilians. Women and girls face heightened risks, while minority communities and displaced people have limited access to protection. Accountability mechanisms have been weakened by the collapse of state institutions.

The war has produced one of the world’s most severe humanitarian crises. Millions of people have faced food insecurity, displacement and disease. Hospitals and water systems have been damaged, and aid agencies have struggled to reach communities because of insecurity, bureaucratic restrictions and funding shortages. The port of Hodeidah is crucial for imports of food and fuel. Humanitarian organizations have called for unhindered access and a durable ceasefire.

Economy

Yemen is one of the poorest countries in the region. Before the war, oil exports, agriculture, trade and remittances contributed to the economy. Conflict damaged infrastructure, disrupted production and divided financial institutions. Oil and gas exports have been interrupted by attacks on ports and pipelines. The currency has depreciated, public salaries have gone unpaid, and inflation has reduced purchasing power.

Economic authority is divided between rival administrations, which issue different regulations and collect taxes and customs revenue. The central bank itself has competing branches and policies. Public services vary by territory, and humanitarian assistance has become a major source of income for many families. Reconstruction requires security, restored trade, functioning financial institutions and political agreement over revenue distribution.

Agriculture, trade and public finance

Agriculture employs a large share of the rural population. Coffee, qat, cereals, fruit and livestock are produced in different regions. Qat cultivation consumes substantial water and competes with food crops. Terraced farming in the highlands conserves soil and water, while irrigation supports crops in valleys. Conflict, fuel shortages, drought and land mines have reduced cultivation and access to markets.

Yemen imports much of its food, fuel and medicine. Ports on the Red Sea and Gulf of Aden are essential for trade, particularly Hodeidah and Aden. Restrictions and fighting have raised costs and delayed shipments. Remittances from Yemenis abroad support households. The state budget has been undermined by reduced oil income, divided institutions and the inability to collect revenue consistently.

Water supply and sanitation

Water scarcity is one of Yemen’s most serious long-term challenges. The country has no permanent rivers, and communities rely on groundwater, rainfall and wells. Aquifers have been depleted by population growth, irrigation and urban use. Water delivery in cities is intermittent, and many households purchase water from private vendors. Sanitation systems are limited, contributing to outbreaks of cholera and other diseases.

Traditional water management includes terraces, cisterns and local sharing arrangements. These systems have been damaged by conflict and underinvestment. International agencies have supported emergency water trucking, repairs to networks and sanitation projects. Sustainable water governance is essential to future food security and urban stability.

Demographics

Yemen has a young and rapidly growing population, much of it living in rural areas and highland towns. Sanaa is the largest city, while Aden, Taiz, Hodeidah and Ibb are major urban centres. Conflict has displaced millions inside the country and driven many to seek refuge in neighbouring states. Population estimates are uncertain because of migration and limited census activity.

People, languages and religion

Most Yemenis are Arabs, with communities of African, South Asian and other ancestry. Tribal identities remain important in parts of the country, though urbanization and state institutions have changed social structures. Arabic is the official language and is spoken in regional dialects. Mehri and Soqotri, South Arabian languages, are spoken in eastern Yemen and on Socotra. English is used in some business and education settings.

Most Yemenis are Muslims. Zaydi Shi'a communities are concentrated in the northern highlands, while Sunni Shafi'i communities are widespread in the south and coastal regions. Small Ismaili communities and a historic Jewish community have also been present. Religious institutions and tribal authorities influence local life, but affiliation varies by region and family.

Education and health

Yemen’s education system has been severely disrupted by conflict. Schools have been damaged or used as shelters, teachers have gone unpaid and millions of children have faced interruptions to learning. Girls’ attendance is affected by poverty, insecurity and early marriage. Universities in Sanaa, Aden and other cities continue to operate with limited resources.

Healthcare infrastructure has been damaged by airstrikes, ground fighting and shortages of staff and medicine. Cholera, malnutrition and other preventable illnesses have affected large populations. Maternal and child health services are inadequate in many districts. Humanitarian organizations provide vaccination, nutrition and emergency care, but access varies across territory and depends on funding and security.

Culture

Yemeni culture reflects ancient South Arabian kingdoms, Islamic scholarship, tribal traditions and maritime connections. Architectural forms include tower houses built from stone and mud brick, decorated facades and fortified villages. Sanaa’s old city preserves dense historic neighbourhoods, while Shibam is known for its high-rise mud-brick buildings. War and neglect have threatened historic structures and archaeological sites.

Theatre, media and sport

Yemeni theatre and literature have developed despite limited resources and political pressure. Oral poetry, storytelling and music preserve local histories and social commentary. Media outlets have been divided among political authorities, and journalists face censorship, detention and violence. Digital communication has helped document conflict but is vulnerable to shutdowns and surveillance.

Football is the most popular sport, though conflict has interrupted leagues and facilities. Traditional sports and equestrian activities remain part of rural life. Cultural festivals and public celebrations have been curtailed by insecurity and economic hardship. Yemeni artists and writers in the diaspora continue to publish and perform, bringing the country’s history and current experiences to international audiences.
