The total area of the Wilno Voivodeship was 29,011 square kilometers, with a population of 1.276 million. Following the German and Soviet invasion of Poland and the reshaping of Europe, Poland's borders were redrawn at the insistence of Soviet leader Joseph Stalin at the Tehran Conference, and the Wilno Voivodeship was incorporated into the Lithuanian and the Byelorussian Soviet Socialist Republics. Many of the Polish population were forcibly resettled at the end of World War II. Since 1991, the former territory of the voivodeship is split between sovereign Lithuania and sovereign Belarus.
