After 150 years apart, Marxist South Yemen and conservative North Yemen are unified as the Republic of Yemen. Ali Abdullah, president of North Yemen, became the new country's president, and Ali Salem Al-Baidh, leader of the South Yemeni Socialist Party, vice president. The first free elections were held in 1993.
Situated at the southern tip of the Arabian Peninsula, Yemen was divided between the British and the Ottomans in the mid-19th century. The Turks were expelled from the north in 1918, but the British continued to dominate the south until 1967, when the Arab world's first and only Marxist state, the People's Republic of South Yemen, was established.
The unification of Yemen in 1990 did not go as smoothly as hoped; economic troubles in 1991 brought Yemen to the brink of collapse, and a civil war in 1994 between southern secessionists and Yemen's northern-based government temporarily dissolved the Yemeni union. Free elections resumed in 1997.
