Prince Charles Is Oldest Heir To The Throne In History - When Will He Be King? 

Since the age of three, the Duke of Cornwall and Duke of Rothesay, i.e., Prince Charles, has been awaiting his turn to sit on the thrown as head of the Commonwealth. Over 60 years later, he is still waiting as he turns 71 in November 2019, making him the oldest and longest-serving heir to the British throne in history.

The Prince of Wales was born on November 14, 1948 around 9:14 pm in Buckingham Palace. So, when, and if, Prince Charles takes over the thrown after his mother, he will be the oldest king to wear the crown. The title was previously held by William IV, who succeeded the British throne in 1830 at the age of 64.

The longest-serving Prince of Wales, Charles will be celebrating his 71st birthday in India as he embarks on a royal engagement to meet President Ram Nath Kovind. Of late, he has been attending meetings and events on the Queen’s behalf, in preparation of the day he becomes the King. But that day may as well be a decade away.

The Queen’s parents- King George VI and her mother, Queen Elizabeth I- died at the age of 56 and 101 respectively, after which Elizabeth II ascended the throne at the age of 25. So, if the Queen, 93, takes after her mother, and lives 'til the age of 101, Prince Charles may not be crowned 'til he is 78. And seeing the robust health and strong physical state the Queen is in, the scenario looks like a possibility.

Being the father of two and grandfather of four, Prince Charles is all set to celebrate his 71st birthday and jokingly shared how he is aware of the fact that he has “reached the biblical threshold of three score years and 10, with all the scars that go with it”.
