In the 1850s (after the Crimean War), Focșani grew in importance as the center of activities in favor of the union between Wallachia and Moldavia (the Danubian Principalities), leading to the double election of Alexandru Ioan Cuza in Iași and Bucharest. Following this, it housed a Central Commission regulating the common legislation of the two countries, as well as the High Court of Justice. Both institutions were disestablished in 1864, when the Romanian Principality was founded as a unified state. Focșani's role in the forming of the modern Romanian state is immortalized in the Union Square Obelisk.
