 In 1944–53, there were several anti-Soviet resistance groups in Moldova; however the NKVD and later MGB managed to eventually arrest, execute or deport their members.In the postwar period, the Soviet government organized the immigration of working age Russian speakers (mostly Russians, Belarusians, and Ukrainians), into the new Soviet republic, especially into urbanized areas, partly to compensate for the demographic loss caused by the war and the emigration of 1940 and 1944.In the 1970s and 1980s, the Moldavian SSR received substantial allocations from the budget of the USSR to develop industrial and scientific facilities and housing.
