Former Bosnian Serb leader Radovan Karadzic has been sentenced to 40 years in prison after the U.N. International Criminal Tribunal for the former Yugoslavia (ICTY) found him guilty of genocide at Srebrenica.Karadzic, 70, was charged on two counts of genocide and one count each of persecution, extermination, murder as a crime against humanity and murder as a war crime, deportation, inhumane acts, terror, unlawful attacks and taking hostages.The court cleared him of genocide charges related to crimes committed in seven municipalities other than Srebrenica due to insufficient evidence to prove the intent.A psychiatrist by vocation, Karadzic emerged as the Bosnian Serb political leader shortly before Yugoslavia began disintegrating in a series of wars in 1991. His military chief, general Ratko Mladic, is still on trial at ICTY on similar charges.The court ruled that Karadzic was responsible for a campaign of terror with the aim of ethnically cleansing a part of Bosnia and Herzegovina in the 1992-95 war by pitting Orthodox Serbs against Muslim Bosniaks and Catholic Croats.The campaign included the relentless shelling and sniping of Sarajevo, attacks on other towns and - in what is usually described as the worst atrocity in Europe since the Holocaust - the 1995 genocide at Srebrenica, where forces under Karadzic's command executed around 8,000 Bosniak boys and men.ICTY chief prosecutor Serge Brammertz has described Karadzic's trial as the most important in the tribunal's 23-year history.Key dates in the life of former Serb leader Radovan Karadzic:June 19, 1945: Born in Savnik, Yugoslavia, in what is now the Republic of Montenegro.July 12, 1990: A founding member of the Serbian Democratic Party in Bosnia-Herzegovina.March 27, 1992: Becomes president of Serbia's National Security Council.April 6, 1992: Bosnia is recognized as an independent state by the United Nations.May 12, 1992: Elected president of the three-person presidency of the Serbian republic in Bosnia.Dec. 17, 1992 - July 19, 1996: Serves as sole president of Serb Republic in Bosnia.
