Explanation:
The Bosnian War started on 6th April 1992, was an armed conflict that happened in Bosnia and Herzegovina, and lasted till 14th December 1995.
During the war, Serbs with the help of the former Yugoslavian military expelled many Bosniaks (Bosnian Muslims) and Croats out of Bosnia and Herzegovina.
