The former PDRY is located on the southern coast of the Arabian Peninsula. Founded in 1967 as the People's Democratic Republic of Southern Yemen, it was renamed the People's Democratic Republic of Yemen (PDRY) in 1970. Until 1990, the PDRY was governed by the 111-member Supreme People's Council under a constitution enacted in 1970. The country's capital was Aden. On May 22, 1990, in accordance with a constitution drafted nine years earlier, the People's Democratic Republic of Yemen and the Yemen Arab Republic (YAR) established a unified state.
