As King Frederik IX and Queen Ingrid had no sons, it was expected that the king's younger brother, [[Knud, Hereditary Prince of Denmark|Prince Knud]], would inherit the throne, in accordance with Denmark's succession law (Royal Ordinance of 1853).

However, in 1953, an [[Act of Succession (Denmark)|Act of Succession]] was passed, primarily changing the method of succession to [[male-preference primogeniture]], allowing his daughters to succeed him if he had no sons. As a result, his eldest daughter, Margrethe, became [[heir presumptive]].
