In the 19th century the Netherlands administered the archipelago that would become Indonesia, a majority-Muslim country with the largest Muslim population in the world. In the first half of the 20th century hundreds of Indonesian students, sailors, baboes and domestic workers lived in the Netherlands, thus constituting the first sizable Muslim community. In 1932, Indonesian workers established the Perkoempoelan Islam (Islamic Association), which was a self-help organization that lobbied for the establishment of a Muslim cemetery and a mosque in the Netherlands.
