However, at the foundation of the Kingdom of the Netherlands in 1813, the "Wilhelmus" had fallen out of favour. Having become monarchs with a claim to represent the entire nation and stand above factions, the House of Orange decided to break with the song which served them as heads of a faction, and the "Wilhelmus" was replaced by Hendrik Tollens' song "Wien Neêrlands bloed door d'aderen vloeit", which was the official Dutch anthem from 1815 until 1932. However, the "Wilhelmus" remained popular and lost its identification as a factional song, and on 10 May 1932, it was decreed that on all official occasions requiring the performance of the national anthem, the "Wilhelmus" was to be played – thereby replacing Tollens' song.
