Throughout the era of British colonialism, the British retained the institution of Grand Mufti in some Muslim areas under their control and accorded the Grand Mufti of Jerusalem the highest political stature in Palestine. During World War I (1914–1918), there were two competing Grand Muftis of Jerusalem, one endorsed by the British and one by the Ottoman Empire. When Palestine was under British rule, the Grand Mufti of Jerusalem was a position appointed by the British Mandate authorities.
