On February 6th, 1952, George VI was found dead in his bed at
Sandringham House. A heavy smoker, he had been suffering from multiple
illnesses, including lung cancer, and had died in his sleep of a
coronary thrombosis at the age of 56.
He was succeeded on the
throne by his eldest daughter, Princess Elizabeth, who was only 25 years
old at the time. She has now reigned as Elizabeth II for 64 years, and is the longest reigning British Monarch, as well as the longest reigning Queen Regnant in world history.
