William IV of the United Kingdom

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. William IV (William Henry; 21 August 1765 - 20 June 1837) was King of the United Kingdom of Great Britain and Ireland and of Hanover from 26 June 1830 until his death on 20 June 1837. William, the third son of George III and younger brother and successor to George IV, was the last king and penultimate monarch of the House of Hanover. He served in the Royal Navy in his youth and was, both during his reign and afterwards, nicknamed the "Sailor King". He served in North America and the Caribbean, but saw little actual fighting. Since his two older brothers died without leaving legitimate issue, he inherited the throne when he was 64 years old.
