For taking Austrian side in Austro-Turkish wars (late 17th, early 18th century), Serbs were forced to leave their fatherland and inhabit Austrian territories across river Sava and Danube. Serbian Patriarch as an institution eventually settled in Sremski Karlovci and that’s how this picturesque small town became Serbian cultural center and “emigration capital” during Turkish occupation. Within same historical context, Austrians built the most powerful fortress on the river Danube, A.K.A. “Gibraltar on the Danube”. Wright across the river, town of Novi Sad started to flourish and it would eventually take over the role of the most important city in Vojvodina Province.
