Like most Slavic groups, the Serbs have a tradition of patrilineal descent reckoning, and this is reflected in many aspects of the culture, for example, inheritance of the slava or family patron saint. The kindred of a Serb can include individuals spanning ten generations; the Ѕerbian language has carefully defined these people with respect to their various roles and relationships in a rich vocabulary of kinship terminology.
North of the Sava and Danube rivers, there is a vast plain sandwiched between branches of the Carpathian and Alpine mountain ranges. In prehistory, it was a great inland sea; today, it is an area of fertile land, peppered history and vibrant folkloric heritage. This is the Pannonian Zone.
