The Colorado effort to reduce Blancos to only three departments caused a Blanco uprising of 1897, which ended with the creation of 16 departments, of which the Blancos now had control over six. Blancos were given ⅓ of seats in Congress. This division of power lasted until the President Jose Batlle y Ordonez instituted his political reforms which caused the last uprising by Blancos in 1904 that ended with the Battle of Masoller and the death of Blanco leader Aparicio Saravia.
