The oldest monarch at the start of his reign was King William IV, who succeeded the throne in 1830 at the age of 64. Meanwhile, the oldest heir to the throne in history was Sophia of Hanover, who was declared the rightful heir to Queen Anne by the Act of Settlement of 1701, but she never became queen because she died in 1714 at the age of 83, two months before Queen Anne died.
