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.[1] The term was regularly, if informally, used byRobert Walpole by the 1730s.[2] It was used in theHouse of Commons as early as 1805,[3] and it was certainly in parliamentary use by the 1880s,[4] although did not become the official title until 1905, whenHenry Campbell-Bannerman was prime minister.
Following the succession ofGeorge I in 1714, the arrangement of a commission of lords of the Treasury (as opposed to a single lord high treasurer) became permanent.[19] For the next three years, the government was headed byCharles Townshend, 2nd Viscount Townshend, who was appointedSecretary of State for the Northern Department.[20] Subsequently, LordsStanhope andSunderland ran the government jointly,[21] with Stanhope managing foreign affairs and Sunderland domestic.[21] Stanhope died in February 1721 and Sunderland resigned two months later;[21] Townshend andRobert Walpole were then invited to form the next government.[22] From that point, the holder of theoffice of first lord also usually (albeit unofficially) held the status of prime minister. It was not until theEdwardian era that the titleprime minister was constitutionally recognised.[23] The prime minister still holds the office of first lord by constitutional convention,[24] the only exceptions being theEarl of Chatham and theMarquess of Salisbury.[25]

Due to the gradual evolution of the post of prime minister, the title is applied to early prime ministers only retrospectively;[23] this has sometimes given rise to academic dispute.William Pulteney, 1st Earl of Bath, andJames Waldegrave, 2nd Earl Waldegrave, are sometimes listed as prime ministers.[100] Bath was invited toform a ministry byGeorge II whenHenry Pelham resigned in 1746,[101] as was Waldegrave in 1757 after the dismissal ofWilliam Pitt the Elder,[102] who dominated the affairs of governmentduring the Seven Years' War. Neither was able to command sufficient parliamentary support to form a government; Bath stepped down after two days[100] and Waldegrave after four.[102] Modern academic consensus does not consider either man to have held office as prime minister;[103][failed verification] they are therefore listed separately.
