HMS Liverpool was a Royal Navy Endymion-class frigate, reclassified as a fourth rate. She was built by Wigram, Wells and Green and launched at Woolwich on 21 February 1814. She was built of pitch-pine, which made for speedy construction at the expense of durability.

The Persian Gulf campaign of 1819 was a British punitive expedition, principally against the Arab maritime force of the Al Qasimi 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", would become known as the "Trucial Coast" after this treaty. Today, the territory comprises much of the United Arab Emirates.
