There was a Romaniote Jewish community living in Ioannina before World War II, in addition to a very small number of Sephardi. According to Rae Dalven, 1,950 Jews were living in Ioannina in April 1941. Of these, 1,870 were deported by the Nazis to concentration camps on 25 March 1944, during the final months of German occupation. Almost all of the people deported were murdered on or shortly after 11 April 1944, when the train carrying them reached Auschwitz-Birkenau. Only 181 Ioannina Jews are known to have survived the war, including 112 who survived Auschwitz and 69 who fled to join the resistance leader Napoleon Zervas and the National Republican Greek League (EDES). Approximately 164 of these survivors eventually returned to Ioannina.
