National anthem
“Wilhelmus van Nassouwe” (the Wilhelmus) has been the official Dutch national anthem since 10 May 1932, when the Cabinet decided that it should be played on all official occasions.
Before that date, it was also often played or sung on official occasions, such as the investiture of Queen Wilhelmina in 1888.
Until 1932, the official national anthem was Wiens Neerlands Bloed (Whose Dutch blood), which was written for the foundation of the Kingdom of the Netherlands in 1815.
