Srb
Srb lies in the upper Una valley among the mountains of Lika. In the Middle Ages it was the centre of a small district within the Croatian lands, ruled at different times by the Šubić and Nelipić families. A royal charter of 1345 names its fortress, which stood on a hill above the Sredice stream.
The Ottoman conquest in 1520 drove much of the older population away, and pastoral Vlachs settled in the district. By the seventeenth century a garrison occupied the fort at a crossroads between Lapac, Bihać and Udbina, while a Muslim settlement grew below it. The Treaty of Sistova in 1791 brought Srb into the Croatian Military Frontier; Muslim inhabitants moved across the Una and Orthodox settlers came to the deserted area.
