George III was the third Hanoverian king of Great Britain. During his reign, Britain lost its American colonies but emerged as a leading power in Europe. He suffered from recurrent fits of madness and after 1810, his son acted as regent.
George III was born on 4 June 1738 in London, son of Frederick, Prince of Wales and Augusta of Saxe-Gotha
He became heir to the throne when his father died in 1751, succeeding his grandfather George II in 1760. He was the first Hanoverian monarch to use English as his first language. In 1761, George married Charlotte of Mecklenburg-Strelitz and they enjoyed a happy marriage, with 15 children.
He was a poor choice, isolating George from senior politicians. Effective government became almost impossible, and George was increasingly vilified. The instability following Bute's resignation in 1763 did little to solve the crown's financial difficulties, made worse by the Seven Years' War.
