Krupanj
Krupanj lies among the wooded hills of Rađevina, east of the Drina. Its name first appears in Ragusan records in 1417, when it was a mining town visited by merchant caravans. Silver-bearing lead ore from nearby Postenje and Jagodnja was carried across the river to be smelted at Srebrenica. Ragusan merchants settled in Krupanj and maintained a Catholic church there. Mining and the market continued under Ottoman rule. During the First Serbian Uprising, Đorđe Ćurčija and his band took Krupanj in 1804, while local leader Krsta Ignjatović helped defend the district during the years of fighting. In 1837 the town opened its first school, as the Serbian principality established its institutions in the region.
