United Principalities

The United Principalities of Moldavia and Wallachia, also known as the Romanian United Principalities, was the official name of Romania following the 1859 election of Alexandru Ioan Cuza as the Ruling Prince or domnitor of both territories. On 24 January (O.S.) (5 February) 1862, the Principality of Moldavia and the Principality of Wallachia formally united to create the United Principalities. Alongside Transylvania, the principalities became the core of the Romanian nation state.
