Isa ibn Ali Al Khalifa, KCIE, CSI (1848–1932) was the ruler of Bahrain from 1869 until his death. His title was Hakim of Bahrain. He is one of the longest reigning monarchs of the region, a reign lasting 63 years. He was forced by the British Political Advisor to abdicate in 1923, although this "abdication" was never recognised by Bahrainis who considered his successor Hamad only as a viceruler until Isa's death in 1932.
