The Moldavian Autonomous Soviet Socialist Republic, shortened to Moldavian ASSR, was an autonomous republic of the Ukrainian SSR between 12 October 1924 and 2 August 1940, encompassing the modern territory of Transnistria as well as much of the present-day Podilsk Raion of Ukraine. It was an artificial political creation inspired by the Bolshevik nationalities policy in the context of the loss of larger Bessarabia to Romania in April 1918. In such a manner, the Bolshevik leadership tried to radicalize pro-Soviet feelings in Bessarabia with the goal of setting up favorable conditions for the creation of a geopolitical "place d'armes" (bridgehead), in an attempt to execute a breakthrough in the direction of the Balkans by projecting influence upon Romanian Bessarabia, which would eventually be occupied and annexed in 1940 after the signing of the Molotov–Ribbentrop Pact.
