List of prime ministers of the United Kingdom

There is no specific date for when the office of prime minister first appeared, as the role was not created but rather evolved over time through a merger of duties.

Historians generally consider Robert Walpole, who led the government of the Kingdom of Great Britain for over twenty years from 1721,[5] to be the first prime minister.

[7] The first to use the title in an official act was Benjamin Disraeli who signed the 1878 Treaty of Berlin as "Prime Minister of Her Britannic Majesty".

[23] The prime minister still holds the office of first lord by constitutional convention,[24] the only exceptions being the Earl of Chatham and the Marquess of Salisbury.

[100] Bath was invited to form a ministry by George II when Henry Pelham resigned in 1746,[101] as was Waldegrave in 1757 after the dismissal of William Pitt the Elder,[102] who dominated the affairs of government during the Seven Years' War.
