Robert Walpole

Robert Walpole, 1st Earl of Orford (; 26 August 1676 – 18 March 1745), known between 1725 and 1742 as Sir Robert Walpole, was a British Whig statesman who is generally regarded as the de facto first Prime Minister of Great Britain, serving from 1721 to 1742. His formal titles included First Lord of the Treasury, Chancellor of the Exchequer, and Leader of the House of Commons. He is the longest serving prime minister in UK history, with a tenure of over 20 years.

Although the exact dates of Walpole's dominance, dubbed the "Robinocracy", are a matter of scholarly debate, the period 1721–1742 is often used. He dominated the Walpole–Townshend ministry, as well as the subsequent Walpole ministry, and holds the record as the longest-serving British prime minister. W. A. Speck wrote that Walpole's uninterrupted run of 20 years as prime minister "is rightly regarded as one of the major feats of British political history. Explanations are usually offered in terms of his expert handling of the political system after 1720, [and] his unique blending of the surviving powers of the crown with the increasing influence of the Commons".

Walpole was a Whig from the gentry class who was first elected to Parliament in 1701 and held many senior positions. He was a country squire and looked to country gentlemen for his political base. Historian F. O'Gorman says his leadership in Parliament reflected his "reasonable and persuasive oratory, his ability to move both the emotions as well as the minds of men, and, above all, his extraordinary self-confidence".
