Since the defeat of 1893, and even more since the division between "bernardistas" and followers of Hipólito Yrigoyen, no one seriously considered the Unión Cívica Radical as a party with the possibility of accessing power. But, suddenly, the UCR reappeared showing a political and territorial organization far superior to that of the ruling party, and a great revolutionary decision, in the radical revolution of 1905, in which several units of the Army were involved. Exploded on February 4 of that year, it was relatively successful in Buenos Aires, Rosario, Córdoba, Bahía Blanca and Mendoza, but was quickly put down.
