The Nazis used discriminatory laws such as the Nuremberg Laws and violence to force Jews to leave Germany. As Nazi Germany expanded its territory, more and more European Jews came under its control. The invasion of Poland in 1939 brought an additional 3 million Jews under Nazi control, while the invasion of the Soviet Union in the summer of 1941 added another 2.5 million more. Within less than a decade, most European countries in which Jews lived would be invaded, occupied, or annexed by Nazi Germany. Within a dozen years, two out of three European Jews would be dead, and European Jewish life changed forever.
