Albania differs from other regions in the Balkans in that the peak of Islamization in Albania occurred much later: 16th century Ottoman census data showed that sanjaks where Albanians lived remained overwhelmingly Christian with Muslims making up no more than 5% in most areas (Ohrid 1.9%, Shkodra 4.5%, Elbasan 5.5%, Vlora 1.8%, Dukagjin 0%) while during this period Muslims had already risen to large proportions in Bosnia (Bosnia 46%, Herzegovina 43%, urban Sarajevo 100%), Northern Greece (Trikala 17.5%), Macedonia (Skopje and Bitola both at 75%) and Eastern Bulgaria (Silistra 72%, Chirmen 88%, Nikopol 22%). Later on, in the 19th century, when the process of Islamization had halted in most of the Balkans and some Balkan Christian peoples like Greeks and Serbs had already claimed independence, Islamization continued to make significant progress in Albania, especially in the South.
