Luč (Hungarian: Lőcs, German: Lutsch, Serbian: Луч)is a settlement in the region of Baranja, Croatia. Administratively, it is located in the Petlovac municipality within the Osijek-Baranja County. Population is 435 people.
Until the end of World War II, the majority of the inhabitants was Danube Swabian, also called locally as Stifolder, because their ancestors arrived in the 17th and 18th centuries from Fulda (district).[2] Most of the former German settlers were expelled to Allied-occupied Germany and Allied-occupied Austria in 1945-1948, consequent to the Potsdam Agreement.[3]
