The Persian Gulf campaign of 1819 was a British punitive expedition, principally against the Arab maritime force of the Qawasim in the Persian Gulf, which embarked from Bombay, India in November 1819 to attack Ras Al Khaimah. The campaign was militarily successful for the British and led to the signing of the General Maritime Treaty of 1820 between the British and the Sheikhs of what was then known as the "Pirate Coast" and would become known as the Trucial Coast or Trucial States after this treaty. Today, the Trucial States comprise the United Arab Emirates.
