Oder-Neisse Line
Polish-German border along the Oder and Neisse rivers proposed by the Allied Powers at the end of
World War II. After inconclusive talks at the
Yalta Conference to redraw the Polish-German border so as to grant more territory to Poland, the Soviet Union unilaterally occupied all territory east of its preferred Oder-Neisse line. The U.S. and Britain, dubious about Soviet domination of an enlarged Poland, protested the action but eventually agreed to the provisional border, which was not recognized by West Germany until it signed treaties with the Soviet Union and Poland in 1970.
