List of Prime Ministers of the United Kingdom

The prime minister of the United Kingdom is the principal minister of the crown of His Majesty's Government, and the head of the British Cabinet. There is no specific date for when the office of prime minister first appeared, as the role was not created but rather evolved over a period of time through a merger of duties. However, the term was regularly, if informally, used of Walpole by the 1730s. It was used in the House of Commons as early as 1805, and it was certainly in parliamentary use by the 1880s.Template:Sfnm In 1905, the post of prime minister was officially given recognition in the order of precedence. Modern historians generally consider Robert Walpole, who led the government of Great Britain for over twenty years from 1721, as the first prime minister. Walpole is also the longest-serving British prime minister by this definition.Template:Sfn However, Henry Campbell-Bannerman was the first and Margaret Thatcher the longest-serving prime minister officially referred to as such in the order of precedence. The first to use the title in an official act was Benjamin Disraeli, who signed the Treaty of Berlin as "Prime Minister of Her Britannic Majesty" in 1878.

Strictly speaking, the first prime minister of the United Kingdom of Great Britain and Ireland was William Pitt the Younger. The first prime minister of the current United Kingdom (the United Kingdom of Great Britain and Northern Ireland), was Bonar Law,Template:Sfn although the country was not renamed officially until 1927, when Stanley Baldwin was the serving prime minister.

Due to the gradual evolution of the post of prime minister, the title is applied to early prime ministers only retrospectively; this has sometimes given rise to academic dispute. Lord Bath and Lord Waldegrave are sometimes listed as prime ministers.Template:Sfn Bath was invited to form a ministry by George II of Great Britain when Henry Pelham resigned in 1746,Template:Sfn as was Waldegrave in 1757 after the dismissal of William Pitt the Elder,Template:Sfn who dominated the affairs of government during the Seven Years' War. Neither was able to command sufficient parliamentary support to form a government; Bath stepped down after two days and Waldegrave after four. Modern academic consensus does not consider either man to have held office as prime minister; they are therefore listed separately.

## 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,Template:Sfn 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 prepubescent nephew Edward VI of England; William Cecil, 1st Baron Burghley (Lord High Treasurer, 1572–1598),Template:Sfn was the dominant List of ministers to Elizabeth I; Burghley's son Robert Cecil, 1st Earl of Salisbury, succeeded his father as chief minister to (1598–1603) and was eventually appointed by James VI and 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, Lord Godolphin (1702–1710) and Lord Oxford (1711–1714), ran the government of Queen Anne.

## From 1707 to 1721

Following the succession of [[George I of Great Britain|Template:Nowrap]] 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 Lord Townshend, who was appointed Secretary of State for the Northern Department.Template:Sfn Subsequently, Lord Stanhope and Lord Sunderland ran the government jointly,Template:Sfnm with Stanhope managing foreign affairs and Sunderland domestic.Template:Sfnm Stanhope died in February 1721 and Sunderland resigned two months later;Template:Sfnm Townshend and Robert Walpole were then invited to form the next government.Template:Sfnm From that point, the holder of the Template:Em of First Lord also usually (albeit unofficially) held the status of prime minister. It was not until the Edwardian era that the title Template:Em was constitutionally recognised.Template:Sfn The prime minister still holds the office of First Lord by constitutional convention,Template:Sfn the only exceptions being Lord Chatham (1766–1768) and Lord Salisbury (1885–1886, 1886–1892, 1895–1902).Template:Sfnm
