In Argentina, 'UCR' is the acronym of a political party that was founded in the late nineteenth century to oppose the abuses and corruption of the ruling autonomist party. At first it was called Civic Union of Youth, which to avoid age discrimination was changed to Civic Union, and years later was divided into two currents by political differences called National Civic Union and Anti-Arachnide Civic Union. The latter is what today has the name of Radical Civic Union, which brought internationally some confusions in countries where by influence of the English is confused to radical ("of the root, faithful to its principles") with violent and intransigent groups to the changes, which in Spanish are called "radicalized" to differentiate them.
