In Argentina, the conflict manifested itself as a prolonged civil war between "unitarianas" (i.e. "centralists") and "federalists", which were in some aspects respectively analogous to liberals and conservatives in other countries. Between 1832 and 1852, the country existed as a confederation, without a head of state, although the federalist governor of Buenos Aires province, Juan Manuel de Rosas, was given the powers of debt payment and international relations and exerted a growing hegemony over the country. A national constitution was only enacted in 1853, reformed in 1860, and the country reorganized as a federal republic led by a liberal-conservative elite. After Uruguay achieved its independence, in 1828, a similar polarization crystallized between "blancos" and "colorados", where the agrarian conservative interests were pitted against the liberal commercial interests based in Montevideo, and which eventually resulted in the "Guerra Grande" civil war (1839–1851).
