William IV (1765 - 1837). William IV was King of the United Kingdom of Great Britain and Ireland and King of Hanover from 26 June 1830 until his death in 1837. The third son of George III, William succeeded his elder brother George IV, becoming the last king and penultimate monarch of Britain's House of Hanover. William served in the Royal Navy in his youth, spending time in North America and the Caribbean, and was later nicknamed the Sailor King. In 1789, he was created Duke of Clarence and St Andrews. In 1827, he was appointed as Britain's first Lord High Admiral since 1709. As his two older brothers died without leaving legitimate issue, he inherited the throne when he was 64 years old. His reign saw several reforms: the poor law was updated, child labour restricted, slavery abolished in nearly all of the British Empire, and the British electoral system refashioned by the Reform Act 1832. Although William did not engage in politics as much as his brother or his father, he was the last monarch to appoint a British prime minister contrary to the will of Parliament. He granted his German kingdom a short-lived liberal constitution. At the time of his death William had no surviving legitimate children, but he was survived by eight of the ten illegitimate children he had by the actress Dorothea Jordan, with whom he cohabited for twenty years. Late in life, he married and apparently remained faithful to the young princess who would become Queen Adelaide. William was succeeded by his niece Queen Victoria in the United Kingdom, and his brother King Ernest Augustus in Hanover. William was born in the early hours of the morning on 21 August 1765 at Buckingham House, the third child and son of King George III and Queen Charlotte. He had two elder brothers, George, Prince of Wales, and Frederick, and was not expected to inherit the Crown. He was baptised in the Great Council Chamber of St James's Palace on 20 September 1765. His godparents were the King's siblings: Prince William Henry, Duke of Gloucester and Edinburgh; Prince Henry; and Princess Augusta, Hereditary Duchess of Brunswick-Wolfenbuttel. He spent most of his early life in Richmond and at Kew Palace, where he was educated by private tutors. At the age of thirteen, he joined the Royal Navy as a midshipman, and was present at the Battle of Cape St Vincent in 1780. His experiences in the navy seem to have been little different from those of other midshipmen, though in contrast to other sailors he was accompanied on board ships by a tutor. He did his share of the cooking and got arrested with his shipmates after a drunken brawl in Gibraltar; he was hastily released from custody after his identity became known. He served in New York during the American War of Independence, making him the only member of the British royal family to visit America up to and through the American Revolution. While William was in America, George Washington approved a plot to kidnap him, writing: The spirit of enterprise so conspicuous in your plan for surprising in their quarters and bringing off the Prince William Henry and Admiral Digby merits applause; and you have my authority to make the attempt in any manner, and at such a time, as your judgment may direct. I am fully persuaded, that it is unnecessary to caution you against offering insult or indignity to the persons of the Prince or Admiral. The plot did not come to fruition; the British heard of it and assigned guards to William, who had until then walked around New York unescorted. In September 1781, William held court at the Manhattan home of Governor Robertson. In attendance were Mayor David Mathews, Admiral Digby, and General Delancey. He became a lieutenant in 1785 and captain of HMS Pegasus the following year. In late 1786, he was stationed in the West Indies under Horatio Nelson, who wrote of William: In his professional line, he is superior to two-thirds, I am sure, of the list; and in attention to orders, and respect to his superior officer, I hardly know his equal. The two were great friends, and dined together almost nightly. At Nelson's wedding, William insisted on giving the bride away. He was given command of the frigate HMS Andromeda in 1788, and was promoted to rear-admiral in command of HMS Valiant the following year. William sought to be made a duke like his elder brothers, and to receive a similar parliamentary grant, but his father was reluctant. To put pressure on him, William threatened to stand for the British House of Commons for the constituency of Totnes in Devon.
