July 21 War crimes suspect Radovan Karadzic, who was arrested in Serbia on Monday, started out as defender of the Serbs in the 1992-95 Bosnian war but ended up a fugitive wanted on genocide charges.
Here is a short chronology of what happened in Bosnia:
Feb 29-March 1 - Bosnia's Muslims and Croats vote for independence in referendum boycotted by Serbs.
April 6 - European Union recognises Bosnia's independence. War breaks out and Serbs, under the leadership of Radovan Karadzic, lay siege to capital Sarajevo. They occupy 70 percent of the country, killing and persecuting Muslims and Croats to carve out a Serb Republic.
May - U.N. sanctions imposed on Serbia for backing rebel Serbs in Croatia and Bosnia.
Jan. - Bosnia peace efforts fail, war breaks out between Muslims and Croats, previously allied against Serbs.
April - Srebrenica, Zepa and Gorazde in eastern Bosnia are declared three of six U.N. "safe areas". The United Nations Protection Force UNPROFOR deploys troops and Bosnian Serb Army (VRS) attacks stop. But the town remains isolated and only a few humanitarian convoys reach it in the following two years. 1994:
March - U.S.-brokered agreement ends Muslim-Croat war and creates a Muslim-Croat federation.
March - Bosnian Serb President Radovan Karadzic orders that Srebrenica and Zepa be entirely cut off and aid convoys be stopped from reaching the towns.
July 9 - Karadzic issues a new order to conquer Srebrenica.
July 11 - Bosnian Serbs troops, under the command of General Ratko Mladic, capture the eastern enclave and U.N. "safe area" of Srebrenica, killing about 8,000 Muslim males in the following week. The U.N. war crimes tribunal in The Hague indicts Karadzic and Mladic for genocide for the siege of Sarajevo.
August - NATO starts air strikes against Bosnian Serb troops.
Nov. 21 - Following NATO air strikes against Bosnian Serbs, Bosnian Muslim President Alija Izetbegovic, Croatian President Franjo Tudjman and Serbian President Slobodan Milosevic agree to a U.S.-brokered peace deal in Dayton, Ohio.
Dec. 14 - The three leaders sign the Dayton peace accords in Paris, paving the way for the arrival of a 66,000-strong NATO peacekeeping Implementation Force (IFOR) in Bosnia. The international community establishes a permanent presence in the country through the office of an international peace overseer.
July - West forces Karadzic to quit as Bosnian Serb president.
September - Nationalist parties win first post-war election, confirming Bosnia's ethnic division.
-- Having lost power, Karadzic goes underground.
Feb. 12 - Former Yugoslav President Slobodan Milosevic goes on trial charged with 66 counts of genocide and war crimes in Bosnia, Croatia and Kosovo.
Dec. - Ex-NATO commander tells the court Milosevic knew Bosnian Serbs planned to massacre Muslims in Bosnia in 1995. 2004:
June 11 - In a belated abandonment of its endless denials and under strong international pressure, the Bosnian Serb government make a landmark admission -- that Serbs indeed massacred thousands of Muslims at in Srebrenica, on Karadzic's orders.
March 11 - Milosevic is found dead in his cell in The Hague.
July 21 - Bosnian Serb wartime president Radovan Karadzic, one of the world's most wanted men for planning and ordering genocide, is arrested.
