When Yugoslavia was invaded by Nazi Germany 1941, Bosnia and Herzegovina was made a part of Nazi-controlled Croatia. Resistance fighters of Bosnia fought against fascist troops from Croatia in guerrilla battles. At the end of World War II, they were reunited back into Yugoslavia but this time under communist rule. Their leader at this point was Marshall Tito. As Marshall Tito died, so did the economy. Economic dissatisfaction grew in Yugoslavia and the Berlin Wall came down, marking an end to an era of the communist rule in much of East Europe.
