Hassan bin Rahma Al Qasimi was the Sheikh (ruler) of Ras Al Khaimah from 1814–1820. He was accused by the British of presiding over a number of acts of maritime piracy, an assertion he denied. Despite signing a treaty of peace with the British in October 1814, a punitive expeditionary force was mounted against Ras Al Khaimah in December 1819 and Hassan bin Rahma was removed as Sheikh of Ras Al Khaimah, which he ceded to the British in a preliminary agreement to the General Maritime Treaty of 1820.
