"Wilhelmus van Nassouwe", usually known just as "Wilhelmus", is the national anthem of the Netherlands. It dates back to at least 1572, making it the national anthem with the oldest music. Although the "Wilhelmus" was not recognized as the official national anthem until 1932, it has always been popular with parts of the Dutch population and resurfaced on several occasions in the course of Dutch history before gaining its present status. It was also the anthem of the Netherlands Antilles from 1954 to 1964.
