 From May 1827 to September 1831, with the exception of brief interventions by Freire, the presidency was occupied by General Francisco Antonio Pinto, Freire's former vice president.The conservative side was under the military leadership of General José Joaquín Prieto and the political guidance of Diego Portales, while the liberal side was under the command of Ramón Freire and Francisco de la Lastra.President Pinto promptly resigned on July 14, handing acting presidential duties not to the vice president but rather to that man's brother, the President of the Senate Francisco Ramón Vicuña.
