 There were many (predominantly Russian) migrants from other parts of the Soviet Union, who often settled in the abandoned family homes of Chechens and Ingushes.The republic lost its Prigorodny District which transferred to North Ossetian ASSR but gained predominantly Russian Naursky District and Shelkovskoy District that is considered the homeland for Terek Cossacks.The Russification policies towards Chechens continued after 1956, with Russian language proficiency required in many aspects of life to provide Chechens better opportunities for advancement in the Soviet system.
