Florencio Varela was born in Buenos Aires, Argentina, on February 23, 1808. In 1827, Varela earned a degree from the University of Buenos Aires and joined the cause of the Unitario party. Two years later, under the Federalist dictatorship of Governor Juan Manuel de Rosas, he was exiled to Montevideo in Uruguay. There, he started a family and met several other exile writers and intellectuals who opposed the rule of Rosas.
In 1845, Valera founded the newspaper Comercio del Plata, through which he became one of the fiercest critics of Rosas and encouraged the development of gaucho poetry. On March 20, 1848, he was assassinated by Andrés Cabrera, by request of Rosas.
