Establishment of Primera Junta

Date: May 25, 1810 • Location: Buenos Aires, Argentina

The Primera Junta, the first independent government in Argentina, was established in an open cabildo in Buenos Aires, marking the end of the May Revolution.

The Primera Junta, or Junta Provisional Gubernativa de las Provincias del Río de la Plata, is the most common name given to the first government of what would eventually become Argentina. It was formed on 25 May 1810, as a result of the events of the May Revolution. The Junta initially only had representatives from Buenos Aires. When it was expanded, as expected, with the addition of representatives from the other cities of the Viceroyalty of the Río de la Plata, it became popularly known instead as the Junta Grande or Junta Provisional Gubernativa de Buenos Aires. The Junta operated at El Fuerte, which had been used since 1776 as a residence by the viceroys.
