# Demographic history of Croatian Baranja
## Early 16th century

During the Habsburg-Ottoman wars, at the end of the 17th century, almost the entire Muslim population and a part of the Orthodox population, retreated, along with the Ottoman army. Nevertheless, some Croats, Hungarians and Orthodox settlers (especially Serbs and perhaps also some Vlachs) remained in the villages.
