Editing Frederik IX (section)

==Reign==
{{unreferenced section|date=November 2021}}
From 1942 until 1943, Frederik acted as [[regent]] on behalf of his father who was temporarily incapacitated after a fall from his horse in October 1942.

On 20 April 1947, Christian X died, and Frederik succeeded to the throne. He was proclaimed king from the balcony of [[Christiansborg Palace]] by [[Prime Minister of Denmark|Prime Minister]] [[Knud Kristensen]].

Frederik IX's reign saw great change. During these years, Danish society shook off the restrictions of an agricultural society, developed a welfare state, and, as a consequence of the booming economy of the 1960s, women entered the labour market. In other words, Denmark became a modern country, which meant new demands on the monarchy.

In 1948, one year into the king's reign, the [[Faroe Islands]] obtained [[home rule]] and became a [[self-governing]] country within the [[Danish Realm]].

===Changes to the Act of Succession===

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]].
