John Stuart, 3rd Earl of Bute, (; 25 May 1713 – 10 March 1792), styled Lord Mount Stuart between 1713 and 1723, was a British nobleman who served as the 7th Prime Minister of Great Britain from 1762 to 1763 under George III. He was arguably the last important royal favourite in British politics. He was the first prime minister from Scotland following the Acts of Union in 1707. He was also elected as the first president of the Society of Antiquaries of Scotland when it was founded in 1780. Biography Early life and rise to prominence He was born in Parliament Close, nearby to St Giles Cathedral on the Royal Mile in Edinburgh on 25 May 1713, the son of James Stuart, 2nd Earl of Bute, and his wife, Lady Anne Campbell. He attended Eton College from 1724 to 1730. He went on to study civil law at the Universities of Groningen (1730–1732) and Leiden (1732–1734) in the Netherlands, graduating from the latter with a degree in civil law. A close relative of the Clan Campbell (his mother was a daughter of the 1st Duke of Argyll), Bute succeeded to the Earldom of Bute (named after the Isle of Bute) upon the death of his father in 1723. He was brought up thereafter by his maternal uncles, the 2nd Duke of Argyll and Archibald Campbell, 3rd Duke of Argyll, 1st and only Earl of Ilay. In August 1735, he eloped with Mary Wortley Montagu, whose parents Sir Edward and Lady Mary Wortley Montagu were slow to consent to the marriage. In 1737, he was elected a Scottish representative peer; despite being in London in December of that year, he did not participate in deliberations in the House of Lords. Because of his support for Argyll against Walpole, he was not re-elected in 1741. For the next several years he retired to his estates in Scotland to manage his affairs and indulge his interest in botany. In 1745, Bute moved to Westminster, London, where his family rented a house at Twickenham for forty-five pounds per annum. He met Frederick, Prince of Wales, in 1747 at the Egham Races and became a close friend. After the Prince's death in 1751, Bute was appointed tutor to Prince George, the new Prince of Wales (later George III). Bute arranged for the Prince and his brother Prince Edward to follow a course of lectures
