Nazi concentration camp in World War II .
Originally a town in northern Bohemia (now in the Czech Republic), it became a walled ghetto for Jews in 1941. After the small non-Jewish population was evacuated in 1942, Jewish captives were shipped there from Germany, Austria, Czechoslovakia, Denmark, and The Netherlands. Of the approximately 144,000 Jews sent to Theresienstadt, some 33,000 died in the dense crowding of the ghetto, and 88,000 were shipped on to extermination camps, especially Auschwitz . By the end of World War II, only 19,000 were alive. After the war, the town was resurrected under its Czech name, Terezín.
