The Occupied Enemy Territory Administration (OETA) was a British, French and Arab military administration over areas of the former Ottoman Empire between 1917 and 1920, during and following World War I. The wave of Arab nationalism evolved towards the creation of the first modern Arab state to come into existence, the Hashemite Arab Kingdom of Syria on 8 March 1920. The kingdom claimed the entire region of Syria whilst exercising control over only the inland region known as OETA East. This led to the acceleration of the declaration of the French Mandate for Syria and the Lebanon and British Mandate for Palestine at the 19–26 April 1920 San Remo conference, and subsequently the Franco-Syrian War, in July 1920, in which French armies defeated the newly proclaimed kingdom and captured Damascus, aborting the Arab state.
