What is the name of the Queen's eldest son in The Crown?

The Queen's eldest son in The Crown is Charles, the first child of Queen Elizabeth II and Prince Philip, Duke of Edinburgh.

Born in 1948, Charles became heir apparent when Elizabeth became queen in 1952. The series follows his life from childhood through his difficult relationship with royal duty, his marriage to Lady Diana Spencer, and his long-standing connection with Camilla Parker Bowles.

Viewers sometimes confuse Charles with his younger brothers, Andrew and Edward, or with Philip, who was Elizabeth's husband rather than her son. Charles was also the father of Princes William and Harry. In 2022, after Elizabeth II's death, he became King Charles III, taking the regnal name used in the quiz's source article.

The Crown dramatizes private conversations and compresses events, but Charles's position as Elizabeth's eldest son and heir is a basic historical fact. His full name is Charles Philip Arthur George, and he was born during the reign of his maternal grandfather, King George VI.
