Curzon Line

커즌 선

A proposed demarcation line between Poland and Soviet Russia put forward by British Foreign Secretary Lord Curzon after World War I. Drawn by the Allied Supreme Council in December 1919 on ethnographic principles, it ran from Grodno through Brest-Litovsk along the Bug River to the Carpathians, leaving Lwów/Lviv on the Soviet side. Disregarded in the 1921 Treaty of Riga (which placed Poland's border far to the east), it was revived by Stalin at the Tehran and Yalta conferences and, with 5–8 km digressions in Poland's favour, became the permanent Polish-Soviet border by treaty in August 1945.
