Bernardino de la Trinidad González Rivadavia (May 20, 1780 – September 2, 1845) was the first President of Argentina, then called the United Provinces of Rio de la Plata, from February 8, 1826 to June 27, 1827.
He was educated at the Royal College of San Carlos, but left without finishing his studies.
During the British Invasions he served as Third Lieutenant of the Galicia Volunteers.
He participated in the open Cabildo on May 22, 1810 voting for the deposition of the viceroy.
He had a strong influence on the First Triumvirate and shortly after he served as Minister of Government and Foreign Affairs of the Province of Buenos Aires.
Although there was a General Congress intended to draft a constitution, the beginning of the War with Brazil led to the immediate establishment of the office of President of Argentina; with Rivadavia being the first to be named to the post.
Argentina's Constitution of 1826 was promulgated later, but was rejected by the provinces.
Strongly contested by his political party, Rivadavia resigned and was succeeded by Vicente López y Planes.
Rivadavia retired to Spain, where he died in 1845.
His remains were repatriated to Argentina in 1857, receiving honors as Captain General.
Today his remains rest in a mausoleum located in Plaza Miserere, adjacent to Rivadavia Avenue, named after him.
