History of Yemen
From antiquity to the modern era — the historical eras, key events, and narrative that shaped Yemen.
Overview
Egyptian Sunni caliphs occupied much of north Yemen throughout the 11th century. By the 16th century and again in the 19th century, north Yemen was part of the Ottoman Empire, and in some periods its Imams exerted control over south Yemen.
Former North Yemen
Ottoman control was largely confined to cities with the Imam’s suzerainty over tribal areas formally recognized. Turkish forces withdrew in 1918, and Imam Yahya strengthened his control over north Yemen. Yemen became a member of the Arab league in 1945 and the United Nations in 1947.
Imam Yahya died during an unsuccessful coup attempt in 1948 and was succeeded by his son Ahmad, who ruled until his death in September 1962. Imam Ahmad’s reign was marked by growing repression, renewed friction with the United Kingdom over the British presence in the south, and growing pressures to support the Arab nationalist objectives of Egyptian President Gamal Abdul Nasser.
Shortly after assuming power in 1962, Ahmad’s son, Badr, was deposed by revolutionary forces, which took control of Sanaa and created the Yemen Arab Republic (YAR). Egypt assisted the YAR with troops and supplies to combat forces loyal to the Imamate. Saudi Arabia and Jordan supported Badr’s royalist forces to oppose the newly formed republic. Conflict continued periodically until 1967 when Egyptian troops were withdrawn. By 1968, following a final royalist siege of Sanaa, most of the opposing leaders reached a reconciliation; Saudi Arabia recognized the Republic in 1970.
Former South Yemen
British influence increased in the south and eastern portion of Yemen after the British captured the port of Aden in 1839. It was ruled as part of British India until 1937, when Aden was made a crown colony with the remaining land designated as east Aden and west Aden protectorates. By 1965, most of the tribal states within the protectorates and the Aden colony proper had joined to form the British-sponsored federation of south Arabia.
In 1965, two rival nationalist groups--the Front for the Liberation of Occupied South Yemen (FLOSY) and the National Liberation Front (NLF)--turned to terrorism in their struggle to control the country. In 1967, in the face of uncontrollable violence, British troops began withdrawing, federation rule collapsed, and NLF elements took control after eliminating their FLOSY rivals. South Arabia, including Aden, was declared independent on November 30, 1967, and was renamed the People’s Republic of South Yemen. In June 1969, a radical wing of the Marxist NLF gained power and changed the country’s name on December 1, 1970, to the People’s Democratic Republic of Yemen (PDRY). In the PDRY, all political parties were amalgamated into the Yemeni Socialist Party (YSP), which became the only legal party. The PDRY established close ties with the Soviet Union, China, Cuba, and radical Palestinians.
Republic of Yemen
In 1972, the governments of the PDRY and the YAR declared that they approved a future union. However, little progress was made toward unification, and relations were often strained. In 1979, simmering tensions led to fighting, which was only resolved after Arab League mediation. The northern and southern heads of state reaffirmed the goal of unity during a summit meeting in Kuwait in March 1979. However, that same year the PDRY began sponsoring an insurgency against the YAR. In April 1980, PDRY President Abdul Fattah Ismail resigned and went into exile. His successor, Ali Nasir Muhammad, took a less interventionist stance toward both the YAR and neighboring Oman. On January 13, 1986, a violent struggle began in Aden between Ali Nasir Muhammad and the returned Abdul Fattah Ismail and their supporters. Fighting lasted for more than a month and resulted in thousands of casualties, Ali Nasir’s ouster, and Ismail’s death. Some 60,000 persons, including Ali Nasir and his supporters, fled to the YAR.
In May 1988, the YAR and PDRY governments came to an understanding that considerably reduced tensions including agreement to renew discussions concerning unification,
Historical Eras
The major periods of {country}’s history at a glance.
Ancient Kingdoms
1200 BCE – 628
Yemen was home to the Minaean, Sabaean, and Himyarite kingdoms, which dominated the ancient spice and incense trade routes. These sophisticated states maintained extensive commercial networks stretching to the Mediterranean world. The region subsequently came under Ethiopian and Persian rule before the Persian governor of Yemen embraced Islam in 628 CE, ending the pre-Islamic era.
Islamic & Zaydi Era
628 – 1839
Arab Islamic caliphates extended control over Yemen in the 7th century, and following the fragmentation of the Abbasid caliphate, Zaydi Imams established a durable theocratic order across northern Yemen. The Ottomans absorbed much of the region in the 16th century but were largely expelled by the 1630s, after which Zaydi Imams reasserted authority. In the south, the Kathiridi sultanate and other tribal confederations maintained distinct political structures alongside intermittent Ottoman encroachments from 1849 onward.
Colonial Division
1839 – 1918
Britain captured the strategic port of Aden in 1839, administering it as part of British India and gradually extending protectorates over the surrounding tribal territories. The Ottomans simultaneously pressed their occupation of northern Yemen, though fierce tribal resistance confined effective Turkish control largely to urban centers. The opening of the Suez Canal in 1869 amplified Aden's commercial and strategic importance, deepening the geopolitical division of Yemeni territory.
Divided Independence
1918 – 1990
The collapse of the Ottoman Empire in 1918 brought independence to North Yemen under Imam Yahya and his successors, while the south remained under British rule until 1967, when Marxist NLF guerrillas seized power and eventually proclaimed the People's Democratic Republic of Yemen in 1970. A republican revolution overthrew the Imamate in North Yemen in 1962, sparking a civil war drawing in Egypt, Saudi Arabia, and Jordan. The two Yemeni states engaged in recurrent border conflicts and ideological rivalry through the 1970s and 1980s despite nominal agreements to pursue unification.
Unified Republic
1990 – 2014
North and South Yemen merged on May 22, 1990, forming the Republic of Yemen under President Ali Abdullah Saleh. A southern secessionist uprising in 1994 was swiftly suppressed by northern forces, and a border agreement with Saudi Arabia was reached in 2000. The period nonetheless saw mounting instability, including Houthi insurgencies in the north, a resurgent southern separatist movement, and the growing presence of Al-Qaeda in the Arabian Peninsula.
Civil War & Crisis
2014 – present
Houthi forces seized Sanaa in late 2014 and advanced southward, prompting a Saudi-led military coalition to intervene in 2015 in support of the internationally recognized government. The conflict has produced one of the world's worst humanitarian catastrophes, with widespread famine, disease, and mass displacement. Yemen remains fractured among multiple armed factions, with no durable political settlement achieved.
