In May 1875, the principistas began the Tricolor Revolution, which was defeated later in the year by an unexpected coalition of Blanco leader Aparicio Saravia and the Army under the command of Lorenzo Latorre. Between 1875 and 1890, the military became the center of political power. The country was going through an unstable situation, so representatives of the two major pressure groups, the Asociación Rural del Uruguay —which brought together the hacendados— and the Alto Comercio Montevideano —which brought together businessmen dedicated to foreign trade—, offered Latorre to take power.
