Rahmah ibn Jabir al-Jalahimah (c. 1760–1826) is an Arab ruler in the Persian Gulf and is described by his contemporary, the English traveler and author, James Silk Buckingham, as ‘the most successful and the most generally tolerated pirate, perhaps, that ever infest any sea.’ (James Silk Buckingham, Travels in Assyria, Media, and Persia, Oxford University Press, 1829, p366)
