Earl of Liverpool is a title that has been created twice in British history. The first time was in the Peerage of Great Britain in 1796 for Charles Jenkinson, 1st Baron Hawkesbury, a favourite of King George III. He had already been made Baron Hawkesbury, of Hawkesbury in the County of Gloucester, in 1786, and had succeeded as seventh Baronet of Walcot and Hawkesbury in 1790. His eldest son, the second Earl, served as Prime Minister of the United Kingdom from 1812 to 1827. The peerages became extinct in 1851 on the death of the latter's half-brother, the third Earl, while the baronetcy was inherited by a cousin.
