José Félix Esquivel y Aldao was an Argentine Dominican friar and soldier who became a general and then the undisputed Federalist caudillo of Mendoza Province. His ability as a warrior and his brutality became legendary. The largely fictionalized biography that Domingo Faustino Sarmiento wrote fed his legend. An effective ruler, he did much for his province, but was also one of the cruelest federalist leaders.

Francisco Narciso de Laprida was an Argentine lawyer and politician. He was a representative for San Juan at the Congress of Tucumán, and its president on July 9, 1816, when the Declaration of Independence of Argentina was declared.
