Major sources and definitions Geography Formerly known as the states of People's Democratic Republic of Yemen and the Yemen Arab Republic, the Republic of Yemen occupies the southwestern tip of the Arabian Peninsula on the Red Sea opposite Ethiopia, and extends along the southern part of the Arabian Peninsula on the Gulf of Aden and the Indian Ocean.

The country is about the size of France. In A.D. 628 it converted to Islam and in the 10th century came under the control of the Rassite dynasty of the Zaidi sect, which remained involved in North Yemeni politics until 1962. The Ottoman Turks nominally occupied the area from 1538 to the decline of their empire in 1918. The northern portion of Yemen was ruled by imams until a pro-Egyptian military coup took place in 1962. The junta proclaimed the Yemen Arab Republic, and after a civil war in which Egypt's Nasser and the USSR supported the revolutionaries, and King Saud of Saudi Arabia and King Hussein of Jordan supported the royalists, the royalists were finally defeated in mid-1969.
