1857 Wallachian parliamentary election

Elections for the ad hoc Divan were held in Wallachia in September 1857. They restored a liberalizing trend that had been repressed following the 1848 revolution, also giving expression to the national awakening that was taking part among the Romanians. The toppling of the conservative Regulamentul Organic regime in both Danubian Principalities made them possible: following the 1856 Treaty of Paris, Wallachia and Moldavia functioned as a protectorates of the European powers; both were also clients of the Ottoman Empire. Excluding the spontaneous rallies of 1848, this was the first public consultation to be held in eleven years. It ran in conjunction with the Moldavian Divan elections, and, like them, had unusually lax criteria for participation, allowing peasants and guilds to vote by indirect suffrage.

The result in both countries was a sweep for parties which demanded the union with Moldavia. In Wallachia, the progressive National Party, chaired by Constantin A. Crețulescu, was on this topic indistinguishable from the conservative unionist factions, respectively led by brothers Gheorghe Bibescu and Barbu Dimitrie Știrbei. A fourth party, supporting Alexandru II Ghica and Dimitrie Ghica, cooperated with Crețulescu's Committee, although disagreeing over some core policies. These groups held an absolute majority in the Divan, with only some seats going to non-unionists. Together, they formulated demands for union and increased autonomy, postponing debates about universal suffrage; middle-class progressives and the boyar elite also dissuaded peasant deputies from demanding land reform.

The Divan resolutions were taken into account by the European powers, and some were written into the Paris Convention of 1858, which became the new organic law for the "United Principalities". This document outlawed class privilege, but also reinforced old suffrage laws, eliminating the peasant vote. It also prevented the two states from fully merging, keeping the key institutions separate—but a loophole in the text allowed a personal union. In the repeat elections of January 1859, Wallachia voted a conservative "elective assembly", dominated by Bibescu supporters. Pressured by the National Party, which threatened violence, this new parliament gave its vote to a Moldavian, Alexandru Ioan Cuza, who became Hospodar, then Domnitor, of both countries.
