History
The north-east has been settled since the Neolithic, and the salt springs of Tuzla gave the town its medieval name, Soli, and its Turkish one, from tuz, salt. In the Middle Ages the lands of Soli and Usora on the northern edge of the Bosnian kingdom were fought over with Hungary, while the silver mines of Srebrenica, from srebro, silver, drew Ragusan merchants and Saxon miners. The Ottomans took the area between the 1460s and the 1530s and ruled much of it from Zvornik. In 1831 Husein-kapetan Gradaščević of Gradačac led a Bosnian revolt against Ottoman reforms.
Austria-Hungary developed salt works and coal mines around Tuzla from 1878, making it an industrial town with a strong workers' movement. Under Tito, Tuzla became a centre of mining, power generation and chemicals.
The 1992–95 war struck here early and hard. Serb paramilitaries seized Bijeljina and Zvornik in the spring of 1992 and expelled or killed their Bosniak populations; the Posavina corridor around Brčko, the narrow link between the two halves of Serb-held territory, was fought over for three years. Tuzla stayed under a multi-ethnic civilian government, but a shell killed 71 people at the Kapija square on 25 May 1995. In July 1995 Bosnian Serb forces overran the UN safe area of Srebrenica and killed around 8,000 Bosniak men and boys, a crime international courts have ruled genocide. Dayton left Brčko unresolved; arbitration made it a separate district shared by both entities in 2000.
