At the end of World War II the Federal Republic of Yugoslavia was formed which included Bosnia, Serbia, Montenegro, Croatia, Slovenia, and Macedonia. It was made up of several different ethnic groups. Towards the end of the Cold War the different groups and republics were seeking independence. In 1987 Slobodan Milosevic was in power and created a military that was 90% Siberian. By 1991 ethnic tensions were high in Yugoslavia. The republics of Slovenia and Croatia declared independence, which caused Yugoslavia to collapse. The Yugoslav army invaded Croatia and began executing the Croat men. Then Bosnia declared independence and the Serbs targeted Bosniak civilians. By 1995 the military began shelling the city of Srebrenica and 8,000 Bosniaks were killed.
