much of the population of the independent state of croatia was not croat, mostly because of the inclusion of bosnia. it had significant populations of serbs (about 19% of the population of croatia at the time, over 30% of the population of ndh), bosnian muslims (the largest population group of bosnia at the time, and over 10% of the population of ndh), germans, hungarians and others. the catholics (mainly croats, germans and magyars) constituted just over 50% of the 6.3 million population. mile budak, politician and minister of the ndh - also a croatian writer- immediately took the opportunity to proclaim the muslims as "brothers" and wanted to force them to convert to christianity. many croatians agree with the idea that the majority of bosnian muslims are actually croatians who were converted to islam during the invasion of the turks in the 15th century.
