When did Romania sign it's Constitution?
Constitution of Romania
Regulamentul Organic, voted by the respective Assemblies of Moldavia and Wallachia under Imperial Russian occupation in 1831-1832, was the first organic law resembling a constitution ever awarded to the Danubian Principalities.[1] It remained in place until 1858, when the Crimean War removed the two countries from Russian influence and confirmed the rule by several European powers first established by the Treaty of Paris;[2] the Paris Convention of 1858 remained the governing document following the election of Alexandru Ioan Cuza as Domnitor (ruling prince) over the united countries (1859), but was replaced by Cuza's own organic law, entitled Statutul dezvoltător al Convenţiei de la Paris ("Statute expanding the Paris Convention"), in 1864. Although the newly minted state was nominally still a vassal of the Ottoman Empire, it only acknowledged the suzerainty of the Sublime Porte in a formal way.
