About José de la Riva Agüero
José Mariano de la Cruz de la Riva Agüero y Sánchez Boquete was a Peruvian soldier and politician who was the first president of Peru and the second president of North Peru, a constituent country of the Peru–Bolivian Confederation. A leading figure of the Peruvian War of Independence, he was president of Peru in 1823, being the first head of state to serve as President of the Republic and to wear the two-color presidential sash as a symbol of the power he exercised. Although this power was de facto, that is, born from a coup d'état and not by popular will expressed in elections, since it was imposed by the Peruvian Army through the so-called Balconcillo mutiny, which ordered Congress to dismiss the Supreme Governing Junta headed by José de La Mar. He governed for four months before being replaced by the Marquis of Torre Tagle. He was a supporter of liberalism. Although the first representatives of the de la Riva Agüero family were established in Peru since the 17th century, his father just settled down himself in the last quarter of the 18th century. He went first to Chile, then returned to Peru in 1833 and was elected deputy for Lima to the National Convention of 1833, which reincorporated him into the Army with the title of Grand Marshal.
