Alexandru Ioan Cuza was the first domnitor (ruler) of the Romanian Principalities through his double election as prince of Moldavia on 5 January 1859 and prince of Wallachia on 24 January 1859, which resulted in the unification of the two states. He was a prominent figure of the Revolution of 1848 in Moldavia. Following his double election, he initiated a series of reforms that contributed to the modernization of Romanian society and of state structures.

The Moldavian Revolution of 1848 is the name used for the unsuccessful Romanian liberal and Romantic nationalist movement inspired by the Revolutions of 1848 in the principality of Moldavia. Initially seeking accommodation within the political framework defined by the Regulamentul Organic, it eventually rejected it as imposed by foreign powers and called for more thorough political reforms. Led by a group of young intellectuals, the movement was mostly limited to petitioning and constitutional projects, unlike the successful uprising taking place later that year in neighbouring Wallachia, and it was quickly suppressed. This was despite the fact that the Moldavian revolutionaries were more moderate and willing to compromise in their demands for reforms than their Wallachian counterparts, as Moldavian political and social life continued to be dominated by a landed, conservative aristocracy, with the middle class still embryonic.
