King George IV was born on 12 August 1762 in Westminster, London, England, UK. He was married to Caroline of Brunswick. He died on 26 June 1830 in Windsor, Berkshire, England, UK.
He had a famously hostile relationship with his wife Caroline of Brunswick. They separated after the birth of their daughter, Charlotte, and Caroline settled in Italy and was paid an annuity to stay out of England. George desired a divorce but the government would not allow it, and he had her publicly investigated for adultery. After George ascended the throne, Caroline nominally became queen and traveled to England for the coronation but was refused entry to Westminster Abbey on George's order.
