Kalininsky District
On 20 November 1931, the city was renamed Kalinin after the nominal head of state (1919–1946) and affiliate of Josef Stalin, Mikhail Kalinin, who had been born nearby. Simultaneously, Tverskoy District was renamed Kalininsky District. On 29 January 1935 Kalinin Oblast was established, and Kalininsky District was transferred to Kalinin Oblast.
