Francisco Narciso de Laprida

Francisco Narciso de Laprida (October 28, 1786 in San Juan – September 22, 1829) 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.

As a member of the Unitarian Party, the execution of Manuel Dorrego by Juan Lavalle was a hard blow, after which Laprida returned to San Juan. He later had to flee again towards Mendoza Province, to escape Manuel Oribe and Facundo Quiroga's forces. On September 22, 1829, the men of José Félix Aldao, shortly after defeating the unitarian commander Juan Agustín Moyano, reached Laprida's coach and slit his throat; his body was never found.

He is also the great-great-great uncle of Argentine writer Jorge Luis Borges.
