Ethnic and Muslim Bosnians where contained and treated very poorly, as prisoners. It was like the Holocaust for Jews in Poland.
Many people, mostly regular people died in the violence that the Serbs caused as they tried to take over and cleanse the country. In total, 100,000 people were killed in the Serbs violence.
People who were not Serbian had to move out of the North and East regions as fast as possible, because the Serbs took over those regions through violence.
1941 - Bosnia-Herzegovina annexed by pro-Hitler Croatian puppet state. Thousands of Serbs, Jews and Gypsies are sent to the death camps.
1945 - Bosnia-Herzegovina liberated following campaign by partisans under Tito.
1945-1991- Bosnia is part of Socialist Federal Republic of Yugoslavia.
1991 - Following collapse of communism, nationalists win first multi-party elections and form coalition government despite having conflicting goals: Muslim nationalists want centralised independent Bosnia, Serb nationalists want to stay in Belgrade-dominated rump Yugoslavia, Croats want to join independent Croatian state.
1992 - Croat and Muslim nationalists form tactical alliance and outvote Serbs at independence referendum. Serb nationalists are incensed as constitution stipulates that all major decisions must be reached through consensus.
War breaks out and Serbs quickly assume control of over half the republic. Ethnic cleansing is rampant in the newly proclaimed Serb Republic but also widespread in Muslim and Croat-controlled areas.
The Bosnian Serbs, under Radovan Karadzic, lay siege to Sarajevo. The city is controlled by Muslims but they are unable to break out through lines set up to defend surrounding Serb villages. There is bitter fighting as well as many atrocities.
1993 - As tensions rise, conflict breaks out between Muslims and Croats, culminating in the destruction of much of Mostar, including its Old Bridge. The bridge had graced the city since it was built by the Ottomans in the 16th century and was a symbol of Bosnia's cultural diversity.
UN safe havens for Bosnian Muslim civilians are created, to include Sarajevo, Gorazde and Srebrenica.The conflict is extremely complex. Muslims and Serbs form an alliance against Croats in Herzegovina, rival Muslim forces fight each other in north-west Bosnia, Croats and Serbs fight against Muslims in central Bosnia.
