Vechiul Regat
In 1913, as a result of the Second Balkan War, Romania acquired Southern Dobruja from Bulgaria, integrating this historical region within Romania's borders until 1940. In 1923 Romania adopted a new Constitution, and in 1927 it uniformized the traditional administrative systems of Transylvania, Bukovina and Bessarabia with that of the Romanian Old Kingdom. County borders were kept largely intact, with only a couple minor adjustments, as a total of 71 județe existed between 1927 and 1938.
