MASSR meaning in General ?

The Moldavian Autonomous Soviet Socialist Republic (Romanian: Republica Autonomă Sovietică Socialistă Moldovenească, Moldovan Cyrillic: Република Аутономэ Советикэ Cочиалистэ Молдовеняскэ; Ukrainian: Молдавська Автономна Радянська Соціалістична Республіка), shortened to Moldavian ASSR, was an autonomous republic of the Ukrainian SSR between 12 October 1924 and 2 August 1940, encompassing as well the modern territory of Transnistria (today de jure in Moldova, but de facto an independent state; see political status of Transnistria). 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 a goal to return it in the presence of favorable conditions and creation of geopolitical "place d'armes" (bridgehead) to execute a breakthrough in the Balkan direction by projecting influence upon Romanian Bessarabia, which would eventually be occupied and annexed in 1940 after the signing of the Molotov-Ribbentrop Pact.
