Queen Elizabeth II and Prince Philip were the longest-married couple in the history of the British royal family before his April 2021 death, with many children, grandchildren and great-grandchildren to show for it. The pair wed in 1947, five years before the queen ascended to the British throne. One year later, they welcomed their first child, King Charles III, who ascended to the throne following the queen's death in September 2022. Elizabeth and Philip also shared daughter Anne, Princess Royal, Prince Andrew and Prince Edward.
