Pakrac is a city in Croatia, in western Slavonia, in Požega-Slavonia County. The town was first mentioned in 1237. It was captured by the Ottoman Empire in 1543. It was initially a kaza center in the Sanjak of Pojega between 1543 and 1552, then in the Sanjak of Pakrac in the Rumelia Eyalet between 1552 and 1559. Later it was the center of the Sanjak of Pakrac between 1559 and 1601 when the Sanjak seat was moved to Cernik. The Ottoman rule in Pakrac lasted until the Austrians captured it in 1691. In the late 19th and early 20th centuries, Pakrac was part of the Požega County of the Kingdom of Croatia-Slavonia.

The cathedral and the bishop's palace in Pakrac are among the most important monuments of neo-Byzantine architecture in Croatian historicism. In addition, the city also accommodates the Museum of Military and War History, a museum with exhibits related to Croatian, and partly also to world military and war history, and the Pakrac City Museum, a city museum that presents local history and heritage from the city's earliest history to the present day.
