Before Yemen was unified into the present-day
Republic of Yemen in 1990, it existed as two separate countries,
North and
South Yemen.
North Yemen Kingdom of Yemen The Kingdom of Yemen was never a
British protectorate, but was nominally part of the
Ottoman Empire until 1918 and was independent thereafter. Independently, here were two British protectorates (known as the
Eastern and
Western Aden Protectorates) which contained 24 sultanates, emirates and sheikhdoms in the hinterland of Aden. The flag was in use until 1962 when the imam was overthrown and the Yemen Arab Republic was established. A
civil war between republicans (supported by
Egypt) and royalists (supported by
Saudi Arabia) continued until 1970, with the royalist side continuing to use the flag of the kingdom. The flag was adopted on 30 November 1967 when South Yemen declared independence from the United Kingdom until the
Yemeni unification in 1990. It was used again for a few months in 1994 during the existence of the
Democratic Republic of Yemen. {{gallery|mode=nolines|whitebg=y|height=100 ==See also==
