there were 4 big Sufi orders present in the Balkans, moreover Albania and Bosnia ( Croatia being for the bigger part a part of the Austrian Habsburg Empire and Catholc) :
Mevlani, Bektashi, Halveti, Naqshbandi ( to a lesser degree also the Tabani and Rifā῾īyah).
The biggest was actually Mevlani, followed by the Bektahsi and Naqshbandi in which the latter 2 had a more militant connection.
