The Islamization of Albania occurred as a result of the Ottoman conquest of Albania during the late 14th century. The Ottomans through their administration and military brought Islam to Albania through various policies and tax incentives, trade networks and transnational religious links. In the first few centuries of Ottoman rule, the spread of Islam in Albania was slow and mainly intensified during the seventeenth and eighteenth centuries due in part to greater Ottoman societal and military integration, geo-political factors and collapse of church structures. It was one of the most significant developments in Albanian history as Albanians in Albania went from being a largely Christian (Catholic and Orthodox) population to one that is mainly Muslim (Sunni, Bektashi and some other sects), while retaining significant ethnic Albanian Christian minorities in certain regions. The resulting situation where Sunni Islam was the largest faith in the Albanian ethnolinguistic area but other faiths were also present in a regional patchwork played a major influence in shaping the political development of Albania in the late Ottoman period. Apart from religious changes, conversion to Islam also brought about other social and cultural transformations that have shaped and influenced Albanians and Albanian culture.
Albanians began converting to Islam when they became part of the Ottoman Empire in the late 14th century. Albania differs from other regions in the Balkans such as Bulgaria and Bosnia in that until the 1500s, Islam remained confined to members of the co-opted aristocracy and sparse military outpost settlements of Yuruks. Thus, actual conversion to Islam at first occurred mainly amongst the Christian elite, who retained some previous political and economic privileges, and the emerging class of timar or estate holders of the sipahis in the new Ottoman system.
