After the German invasion of Poland in World War II and the division of Poland between Germany and the Soviet Union, many yeshivas that had previously been part of Poland found themselves under Soviet communist rule, which did not tolerate religious institutions. The yeshivas therefore escaped to Vilnius in Lithuania on the advice of Rabbi Chaim Ozer Grodzinski. In Lithuania, the yeshivas were able to function fully for over a year and many of the students survived the Holocaust because of their taking refuge there, either because they managed to escape from there or because they were ultimately deported to other areas of Russia that the Nazis did not reach. Many students, however, did not manage to escape and were killed by the Nazis or their Lithuanian collaborators.
