William Petty, 2nd Earl of Shelburne, Irish-English politician, Prime Minister of Great Britain (born 1737)

William Petty Fitzmaurice, 1st Marquess of Lansdowne, known as the Earl of Shelburne between 1761 and 1784, by which title he is generally known to history, was an Anglo-Irish Whig statesman who was the first home secretary in 1782 and then prime minister in 1782–83 during the final months of the American War of Independence. He succeeded in securing peace with America and this feat remains his most notable legacy.

The prime minister of the United Kingdom is the head of government of the United Kingdom. The prime minister advises the sovereign on the exercise of much of the royal prerogative, chairs the Cabinet, and selects its ministers. Modern prime ministers hold office by virtue of their ability to command the confidence of the House of Commons, so they are invariably members of Parliament.
