In period from 1991 till 1998 in Podunavlje there was self-proclaimed Eastern Slavonia, Baranya and Western Syrmia that was reintegrated into Croatia after signing of Erdut Agreement. Region was declared by local Serbs who promoted survival of Yugoslavia, because of which they had support of Yugoslav People's Army. Local Serb population was further alarmed with comparisons of new Croatian state with World War II Independent State of Croatia and its Jasenovac concentration camp. War has left a heavy mark on both the economy and the interpersonal relationships in region. There were especially strained relations between two largest groups, Croats and Serbs.
