we find marked Mali i Veliki Poganac (Poganetz) which was mentioned as Vlach settlement in 1610 and Lepavina (Lipavina) and Marča Monastery ( Eparchy of Marča ). The Habsburg Empire encouraged people from the Ottoman Empire to settle as free peasant soldiers, establishing the Military Frontiers (Militärgrenze) in 1522 (hence they were known as Grenzers, Krajišnici). When it comes to the Austrian colonization of the Turkish Vlachs to Slavonian Military Frontier and the Vlachs in the Croatian Military Frontier there are some minor differences. Vlachs to western Slavonia or to the Varaždin Generalate of Slavonian Krajina are coming en masse and in a very short time: from yeare 1597 to 1600. To Croatian Krajina and Karlovac Generalate Vlachs arrive in smaller groups but throughout the whole XVII. century. Therefore, the Slavonian region was the first to open the door to the Balkans Vlachs. Biggest number of Vlachs comes from Slavonian Turkish Sandžaks In the first half of the 16th century Serbs settled Ottoman part of Slavonia while in the second part of the 16th century they moved to Austrian part of Slavonia.Serbs were mentioned in the Slavonian area at the end of the 14th century where they along with the Turks plundered and burned villages (Turcos et Rascianos). The Habsburg Empire encouraged people from the Ottoman Empire to settle as free peasant soldiers, establishing the Military Frontiers (Militärgrenze) in 1522 (hence they were known as Grenzers, Krajišnici). They were mostly of Orthodox faith, Serbs and Vlachs (Romance-speaking). Catholic Vlachs were assimilated into Croats, while the Orthodox, under the jurisdiction of the Serbian Orthodox Church, assimilated into Serbs. The militarized frontier would serve as a buffer against Ottoman incursions. The Military frontiers had territory of modern Croatia, Serbia, Romania and Hungary. The colonists were granted small tracts of land, exempted from some obligations, and were to retain a share of all war booty. The Grenzers elected their own captains (vojvode) and magistrates (knezovi). All Orthodox settlers were promised freedom of worship. By 1538, the Croatian and Slavonian Military Frontier were established. Austrians offered land to Serbs and Vlachs which acted as the cordon sanitaire together with Croats against Turkish incursions from the Ottoman Empire. The Military frontiers are virtually identical to the present Serbian settlements (war-time Republic of Serbian Krajina). Colonization into Habsburg lands continued from 1526 to well into the seventeenth century. Serbian communities were dotted about until the twentieth
