follow Catholic rites in private. From 1703 ecclesiastical decrees banned this practice and did not accept that crypto-Catholics could receive holy rites. In 1717, Lady Mary Wortley Montagu, wife of the British Ambassador to the Sublime Porte wrote that her Albanian escort from Belgrade to Istanbul claimed to go to the mosque on Fridays and church on Sundays. At any rate, by 1750, most Christian families had converted to Islam, for the benefits of social networking of the citizens and for financial soundness. Albanians in Kosovo who had been passing as Muslims were declaring themselves Catholics (to avoid conscription) as late as 1845. The Kosovo War Numerous Albanian cultural sites in Kosovo were destroyed during the Kosovo conflict (1998-1999) which constituted a war crime violating the Hague and Geneva Conventions. Of the 498 mosques in Kosovo that were in active use, the International Criminal Tribunal for the former Yugoslavia (ICTY) documented that 225 mosques sustained damage or destruction by the Yugoslav Serb army.

Sufi lodges (tekkes), Muslim theological schools (madrasas) and Islamic libraries sustained damage or destruction resulting in the loss of rare books, manuscripts and other collections of literature. Archives belonging to the Islamic Community of Kosovo with records spanning 500 years were also destroyed.

In the aftermath of the war, a wave of revenge attacks on dozens of Serbian Orthodox churches by Muslim Albanians resulting in being damaged or destroyed.
