Gradačac, Bosnia and Herzegovina

Gradačac is a town and municipality in the northeastern part of Bosnia and Herzegovina. Administratively, Gradačac is part of the Tuzla Canton.

The community of Gradačac was first mentioned in 1302, while the town's first written mention dates from 1465. The town became part of the Ottoman Empire in 1512.

In 1701 the settlement was given the status of a city, and it became the headquarters of a military captaincy in 1710. The captains of the Gradaščević family led the development of the city, and the most famous of them, Husein-kapetan Gradaščević or Zmaj od Bosne, led an uprising that raised to arms most of the Bosnian captains in 1831.

The town has a fort with 18-meter high walls built between 1765 and 1821, and a 22-meter high watchtower, built in 1824 by Husein-kapetan Gradaščević on foundations made originally by the Romans. Husejnija Mosque was built in 1826.
