Bernardo de Irigoyen

Bernardo de Irigoyen (December 18, 1822 — December 27, 1906) was an Argentine lawyer, diplomat and politician.

Born in Buenos Aires, Irigoyen enrolled at the University of Buenos Aires and earned a juris doctor in 1843. He was commissioned by Governor Juan Manuel de Rosas to settle a boundary dispute with Chile (Rosas was charged with the Argentine Confederation's foreign policy during his 1835-52 reign), and from 1844 to 1850, Irigoyen served as Justice Minister in Mendoza Province, where he enacted the first provincial judicial system, as well as reformist military law and land law statutes.

He again negotiated with Chile over the disputed Straits of Magellan (1851), and following Rosas' overthrow, helped draft the 1852 San Nicolás Agreement. He participated in the constitutional assembly that paved the way for the 1860 reunification with secessionist Buenos Aires Province, and was nominated to the Argentine Supreme Court; he refused, however, and resumed his private practice.

Irigoyen returned to public life in 1870 as a provincial legislator, and in 1875, was appointed Minister of Foreign Affairs by President Nicolás Avellaneda. He negotiated boundary treaties with Brazil and Paraguay in the wake of the Paraguayan War against the latter nation, and was named Internal Affairs Minister in 1879, during which tenure he drafted the 1880 federalization of Buenos Aires. He was returned to the Foreign Minister's post by Avellaneda's successor, President Julio Roca, and secured the boundary treaty of 1881 between Chile and Argentina.
