Why Prince Philip's Title Wasn't King
Though he was married to the queen, he was named a prince for a reason.
www.harpersbazaar.comPrince Philip was never a king because, in British royal tradition, the husband of a queen does not take the kingly title. Instead, he received the title Prince Consort (and later Prince Philip, Duke of Edinburgh). When Elizabeth II became queen, the appropriate convention was to style her husband as a consort rather than a king to avoid implying he outranked his wife. He was also not crowned at the 1953 coronation, and his titles were kept separate from the sovereign’s.
For context, other sources explain that queens consort are common, while there is no “king consort” in the same way, so a husband of a queen does not automatically become king [Britannica; Time; Independent; CBS News]. The arrangement reflected longstanding tradition rather than a personal choice by Elizabeth II, and it applied throughout Philip’s time as consort [Britannica][Time][CBS News]. The title he did hold with royal rank was Duke of Edinburgh, among others, and he was later formally designated as a prince in his own right, but never as king [Marie Claire; Time][CBS News].
