==Before the Kingdom of Great Britain==
Before the Union of England and Scotland in 1707, the Treasury of England was led by the Lord High Treasurer. By the late Tudor period, the Lord High Treasurer was regarded as one of the Great Officers of State, and was often (though not always) the dominant figure in government: Edward Seymour, 1st Duke of Somerset (lord high treasurer, 1547–1549), served as lord protector to his young nephew King Edward VI; William Cecil, 1st Baron Burghley (lord high treasurer, 1572–1598), was the dominant minister to Queen Elizabeth I; Burghley's son Robert Cecil, 1st Earl of Salisbury, succeeded his father as Chief Minister to Elizabeth (1598–1603) and was eventually appointed by King James I as lord high treasurer (1608–1612).
By the late Stuart period, the Treasury was often run not by a single individual (i.e., the lord high treasurer) but by a commission of lords of the Treasury, led by the first lord of the Treasury. The last lords high treasurer, Sidney Godolphin, 1st Earl of Godolphin (1702–1710) and Robert Harley, 1st Earl of Oxford (1711–1714), ran the government of Queen Anne.
==From 1707 to 1721==
Following the succession of George I in 1714, the arrangement of a commission of lords of the Treasury (as opposed to a single lord high treasurer) became permanent. For the next three years, the government was headed by Charles Townshend, 2nd Viscount Townshend, who was appointed Secretary of State for the Northern Department. Subsequently, Lords Stanhope and Sunderland ran the government jointly, with Stanhope managing foreign affairs and Sunderland domestic. Stanhope died in February 1721 and Sunderland resigned two months later; Townshend and Robert Walpole were then invited to form the next government. From that point, the holder of the of first lord also usually (albeit unofficially) held the status of prime minister. It was not until the Edwardian era that the title was constitutionally recognised. The prime minister still holds the office of first lord by constitutional convention, the only exceptions being Lords Chatham (1766–1768) and Salisbury (1885–1886, 1886–1892, 1895–1902).
