Communist Yugoslavian leader Tito (Joseph Broz) calls for Yugoslavians to revolt against Nazi rule. 3 Responses to “Today in World War II History—July 4, 1941” Yeoman Jul. 4, 2021 Communist parties everywhere generally opposed the war. . .right up until the Soviet Union was invaded, when they switched their position virtually overnight. Interesting to think this was the last peacetime July 4th in the US up until 1946. Sarah Sundin Jul. 4, 2021 Yep. And that marked the start of the first real resistance groups in Nazi-occupied Europe too – for the same reason. Moscow had encouraged the communist groups to cooperate with the German occupiers. Barbarossa changed everything. Crystal Jul. 4, 2021 Happy fourth of July. I didn’t know this. How interesting.
