[1] The Ottoman conquest did not change the ethnic structure of the area which, in the 16th century, was inhabited only by Christians, Serbs and Serbianized Vlachs.
And although the Islamization of the population of the city of Bihor began with the Ottoman rule, it did not spread outside the town until the end of the 17th century.
[4] After the Balkan Wars and the fall of the Ottoman Empire, heavy pressure led the Muslims from Bihor to move to Bosnia and Herzegovina, Kosovo and Turkey.
In 1914, a few thousand people from Bihor left for Turkey, while followers of Eastern Orthodoxy began to settle in various other parts of Montenegro.
[citation needed] During World War II, Montenegro was occupied by the Italian army, reinforced locally by several detachments of Albanians from Kosovo and Muslims from Bihor.
Based in Montenegro, Chetnik forces under the command of Pavle Đurišić conducted a series of ethnic cleansing operations against Muslims in the region.
A first massacre of the Muslim population from Bihor took place in January 1943 and led to thousands of people fleeing to Albanian-controlled areas such as Rožaje or Peja.
