Between the time of Emperor Agustín de Iturbide's abdication (19 March 1823) and Guadalupe Victoria's assumption of the office of President (10 October 1824), there was a brief period when the executive power of the government was held by a committee. At one time or another the members of this committee included Pedro Celestino Negrete, José Mariano Michelena, Nicolás Bravo, Miguel Domínguez, Vicente Guerrero and Guadalupe Victoria.
