The Dominion of South Arabia (Arabic: سلطان الجنوب العربي), commonly known as South Arabia or British Arabia, was a British dominion that existed from 1896 to 1917. It formed after the fall of the Zanj Empire and its transfer of control to the British. The Empire decided it was best in order to promote their influence in the region (against the growing power of the Ottomans) by uniting the protectorates into one dominion.
The dominion had eventually succumb to revolution and dissolution during the end of the First World War. Many Arabian states later became under the control of the Ottoman Empire and Persia.
