However, Ottoman rule ultimately vastly decreased the number of Catholics in Albania and elsewhere in the Balkans, with waves of conversions to Islam and to a lesser extent Orthodoxy occurring especially in the 17th century after a series of failed rebellions and punitive measures which involved drastic raises in the taxes of the Catholic population. The tribal population of Mirdita saw very few conversions because the ease they had defending their terrain meant the Ottomans interfered less in their affairs, and the Republic of Venice prevented Islamisation in Venetian Albania. Today, Catholic Albanians are mostly found in the areas of Malesia e Madhe, Kiri, Puka, Tropoja (where they are a minority), Mirdita, parts of northwestern Mat, Kurbin, Lezhe, Zadrima, Shkodër and Ulqin (where they live alongside very large numbers of Sunni Muslims), minorities in Kruja and some major cities, as well as scattered pockets throughout Gheg-inhabited areas. While there remained a small Albanian Catholic community in Vlore during Ottoman times, larger numbers of Catholics started were reported in the South after the fall of Communism, often in traditionally Orthodox areas.
