 At the Teheran Conference of 1943 and the Yalta Conference of 1945, Soviet leader Joseph Stalin and British Prime Minister Winston Churchill decided to split their influence in Yugoslavia in half.The Chetniks were almost exclusively made up of Serbs and consisted of "local defence units, marauding bands of Serb villagers, anti-partisan auxiliaries, forcibly mobilised peasants, and armed refugees".The vast majority of Orthodox priests supported the Chetniks with some, notably Momčilo Đujić and Savo Božić, becoming commanders.
