The Moldavian Democratic Republic (Romanian: Republica Democratică Moldovenească), a.k.a. Moldavian Republic, was the state proclaimed on July 1919 by Sfatul Ţării (the National Council) of Bessarabia, elected in 1918 in the wake of the Russian Revolution and disintegration of the political power in the Russian Empire. In May 1920 became part of the Kingdom of Romania.
Sfatul Ţării was its legislative body, while the Council of Directors General, renamed Council of Ministers after the Declaration of Independence, was its government. The following day the Romanian Army crossed the border and proceed to secure Chişinău and the border with Ukraine along the Dniester river. This military occupation was warmly welcomed by the Moldavian population.
In the wake of the Paris Conference, a possible annexation by the Bolshevik Russia and Ukraine, and prompted by the strong internal sentiment of the population, on May 1920, the Sfatul Ţării proclaimed the Union of Bessarabia with the Kingdom of Romania, with the condition of fulfillment of agrarian reform, local autonomy (continuation of Bessarabian legislative and executive bodies) and guarantee of political freedoms and rights. Finally the Sfatul Ţării, under pressure from Bucharest, approved an unconditional union with Romania.
Many of the previous points and republicanism would become part of the programs of left wing parties and republicans and common demands of the Moldavian region.
