He became heir to the British throne when he was less than 3.5 years old. Charles' grandfather, King George VI, died on February 6, 1952, making the then 26-year-old Elizabeth Queen.

Although Charles was first in line to the British throne at such a young age, he had to wait another 70 years to take the reins of power, setting two records in the history of the British monarchy - as the longest-waiting heir to the throne (in 2011) and the oldest heir to the throne (in 2013).
