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. Wilhelmus had a Malay translation of which was sung back when Indonesia was under Dutch colonial rule. During the German occupation of the Netherlands, Arthur Seyss-Inquart, the Nazi Reichskommissar, banned all the emblems of the Dutch royal family, including the "Wilhelmus". It was then taken up by all factions of the Dutch resistance, even those socialists who had previously taken an anti-monarchist stance. The pro-German Nationaal-Socialistische Beweging (NSB), who had sung the "Wilhelmus" at their meetings before the occupation, replaced it with Alle Man van Neerlands Stam ("All Men of Dutch Origin"). The anthem was drawn to the attention of the English-speaking world by the 1942 British war film, One of Our Aircraft Is Missing. The film concerns a Royal Air Force bomber crew who are shot down over the occupied Netherlands and are helped to escape by the local inhabitants. The melody is heard during the film as part of the campaign of passive resistance by the population, and it finishes with the coat of arms of the Netherlands on screen while the "Wilhelmus" is played. Current The "Wilhelmus" is to be played only once at a ceremony or other event and, if possible, it is to be the last piece of music to be played when receiving a foreign head of state or emissary. During international sport events, such as the World Cup, UEFA European Football Championship, the Olympic Games and the Dutch Grand Prix, the "Wilhelmus" is also played. In nearly every case the 1st and 6th stanzas (or repeating the last lines), or the 1st stanza alone, are sung/played rather than the entire song, which would result in about 15 minutes of music. The "Wilhelmus" is also widely used in Flemish nationalist gatherings as a symbol of cultural unity with the Netherlands. Yearly rallies like the "IJzerbedevaart" and the "Vlaams Nationaal Zangfeest" close with singing the 6th stanza, after which the Flemish national anthem "De Vlaamse Leeuw" is sung.
