Queen Elizabeth was suffering from health issues since October last year, which had left her unable to walk or stand.
Keeping up with centuries of traditions and protocols, Charles – the eldest son of Queen Elizabeth – succeeded as the King of Great Britain immediately after the Queen’s demise.
Elizabeth was born in 1926, eight years after the end of the first World War.
She inherited the British throne at age 25 in 1952.
