In the early years of Nazi rule, there were efforts to secure the elimination of Jews by expulsion; later, a more explicit commitment was made to extermination. On August 25, 1933, the Nazis signed the Haavara Agreement with Zionists to allow German Jews to emigrate to Palestine in exchange for a portion of their economic assets. The agreement offered a way to leave an increasingly hostile environment in Nazi Germany; by 1939, 60,000 German Jews (about 10% of the Jewish population) had emigrated there. Thereafter, Nazi policy eventually changed to one of total extermination. Nazi doctrine culminated in the Holocaust, or so-called "Final Solution", which was made official at the January 1942 Wannsee Conference.
