In 1940, Soviet Union occupied Bessarabia, northern Bukovina, and Hertza region (the latter a part of the Dorohoi County of rump Moldavia). Since the fall of the Soviet Union in 1991, these territories have been part of the newly independent Moldova and Ukraine.  in Moldova  in Ukraine  In 1951, the Romanian Workers' Party changed the administrative division of Romania to the Soviet model (regions and raions), but reverted to the county system in 1968, although county borders were quite different from the interwar period. A small adjustment was performed in 1981: former counties of Ilfov and Ialomița were reorganized into the present-day counties of Giurgiu, Călărași, Ialomița and Ilfov. A new law on the administrative division from September 6, 1950, abolished the 58 remaining counties (as well as the 424 "plăși" and the 6,276 urban and rural communes), replacing them with 28 regions composed of 177 raions, 148 cities and 4,052 communes. In 1952 the number of regions was reduced to 18: Arad, Bacău, Baia Mare, Bârlad, București, Cluj, Constanța, Craiova, Galați, Hunedoara, Iași, Oradea, Pitești, Ploiești, Stalin, Suceava, Timișoara, and for the first time and autonomous administrative unit based on ethnic criteria, Magyar Autonomous Region ("Regiunea Autonomă Maghiară"). In 1956 the regions of Arad and Bârlad were also dismantled. In 1960, the Hungarian autonomous unit was renamed to "Regiunea Mureș-Autonomă Maghiară" (Mureș-Hungarian Autonomous Region) along with changes in its territory. The final number of regions was 16. In February 1968, the old administrative division of "județ" was reinstated. On January 14, 1968 the law proposal included 35 counties. The final result was substantially different from the situation existent before 1950. This included 39 counties, municipality of Bucharest, 236 cities, out of which 47 were municipalities, and 2706 communes comprising 13149 villages. There were several reasons for restoring the "județe".
