In addition to Catholicism and Sunni Islam, there were pockets of Orthodox (some of whom had converted from Catholicism) in Kavajë, Durrës, Upper Reka and some other regions, while Bektashis became established in Kruja, Luma, Bulqiza, Tetova, and Gjakova. Especially in the tribal regions of the North, religious differences were often mitigated by common cultural and tribal characteristics, as well as knowledge of family lineages connecting Albanian Christians and Albanian Muslims. In the 17th century, although many of the rebellions of the century were at least in part motivated by Christian sentiment, it was noted that many Albanian Muslims also took part, and that, despising Ottoman rule no less than their Christian brethren, Albanian Muslims would revolt eagerly if only given the slightest assistance from the Catholic West.
