Romanian Old Kingdom
The Romanian Old Kingdom (Romanian: Vechiul Regat or just Regat; Hungarian: Regát; German: Regat or Altreich) is a colloquial term referring to the territory covered by the first independent Romanian nation state, which was composed of the Romanian Principalities: Wallachia and Moldavia. The union of the two principalities was achieved when, under the auspices of the Treaty of Paris (1856), the ad hoc Divans of both countries, which were then under Ottoman Empire suzerainty, voted for Alexander Ioan Cuza as their prince.
