Her Son Was First In Line
At any rate, Elizabeth ascended the throne. When she became the queen, her son Charles became the first in line to the throne. Back then, he was three years old. Queen Elizabeth is now the longest-reigning ruler in the history of the British monarch. Charles, on the other hand, is the longest-serving heir.
He Has Also Broken Records
In November 2018, Prince Charles celebrated his 70th birthday. This also made people realize that he is the oldest heir apparent in history. Once he finally becomes the king, he is going to be the oldest monarch in the royal family history. That distinction used to go to William IV. He had been almost 65 years old by the time that he took over the throne in 1830.
