Slavonski Brod, city in eastern Croatia, a port on the Sava River, located just north of the Croatian border with Bosnia and Herzegovina. Slavonski Brod developed as an industrial center after World War II (1939-1945) with a factory producing locomotives and railroad cars. Other enterprises involve metallurgy and wood processing. The outlying area is rich with vineyards and prehistoric sites. An ancient Roman settlement, Marsonia, once existed on about the same site, chosen for its strategic crossing point on the Sava. Slavonski Brod was a part of the Turkish Ottoman Empire from 1536 to 1691. The town suffered considerable damage and emigration during the interethnic armed conflict in the former Yugoslavia between 1991 and 1995. Population (1991) 55,683.
