King Charles III was born on November 14, 1948, at Buckingham Palace in London. As of November 2026, he is 78 years old. He spent more than seven decades as the heir apparent to the British throne, breaking historical records before finally succeeding his mother, Queen Elizabeth II, on September 8, 2022, at the age of 73.
Understanding his age requires looking past a simple number. His life spans a unique era of modern British history, marked by shifting royal traditions, military service, and a decades-long wait for the crown.
Early Life and Education
Born to Princess Elizabeth (later Queen Elizabeth II) and Prince Philip, Duke of Edinburgh, Charles entered the royal line of succession immediately. His grandfather, King George VI, was on the throne. When his mother acceded to the throne in February 1952, three-year-old Charles became the heir apparent and automatically took on the historic title of Duke of Cornwall.
Unlike previous generations of royal heirs, Charles received an education outside palace walls. He attended Cheam School and then Gordonstoun in Scotland, a notoriously rigorous boarding school that his father had also attended. He later broke royal precedent further by enrolling at Trinity College, Cambridge, where he studied archaeology, anthropology, and history, graduating with a Bachelor of Arts in 1970.
Military Service and Early Public Duties
Before taking on full-time royal duties, Charles served in both the Royal Air Force and the Royal Navy. His military training began during his university years when he learned to fly aircraft.
- Royal Air Force: Earned his RAF wings in August 1971.
- Royal Navy: Served on guided-missile destroyers and frigates.
- Command: Commanded the coastal minehunter HMS Bronington in 1976 before ending his active naval service.
On July 1, 1969, at the age of 20, he underwent his formal investiture as the Prince of Wales at Caernarfon Castle. During these decades, he established the Prince's Trust, a charity focused on supporting disadvantaged youth, which became one of his defining legacy projects.
Marriages and Family
Charles's personal life has been a matter of intense public scrutiny for decades.
- Lady Diana Spencer: They married on July 29, 1981, at St Paul's Cathedral. The marriage produced two sons, Prince William and Prince Harry. The couple separated in 1992 and officially divorced on August 28, 1996. Diana passed away tragically in August 1997.
- Camilla Parker Bowles: Following a long-term relationship, Charles married Camilla in a civil ceremony at Windsor Guildhall on April 9, 2005, followed by a service of prayer and dedication at St George's Chapel.
Accession and Reign
Charles spent 70 years as heir apparent, making him the longest-serving heir in British history, a record he held after surpassing King Edward VII's milestone in 2011.
When Queen Elizabeth II died on September 8, 2022, Charles immediately became King at age 73, making him the oldest person to ever ascend the British throne. His formal coronation took place on May 6, 2023, at Westminster Abbey, where he was crowned alongside Queen Camilla. In early 2024, Buckingham Palace announced that he had been diagnosed with cancer and had begun outpatient treatments while scaling back public appearances.
