Deportation of the Balkars
The Soviet government forcibly transferred the entire Balkar population of the North Caucasus to Central Asia on March 8, 1944, during World War II. The expulsion was ordered by NKVD chief Lavrentiy Beria after approval by General Secretary Joseph Stalin. All the 37,713 Balkars of the Caucasus were deported from their homeland in one day.
