Gervasio Antonio de Posadas joins Argentina's second triumvirate

Background. The Second Triumvirate governed the United Provinces of the Río de la Plata following the Revolution of 8 October 1812, which deposed the First Triumvirate. The new body began its functions on 8 October 1812 after the Cabildo appointed its members. It lasted two years, ending when the Assembly of Year XIII decided to replace the Triumvirate with a one-person Supreme Director.

Posadas's Role. Gervasio Antonio de Posadas, an Argentine lawyer and statesman, joined the Second Triumvirate in 1813. He replaced Antonio Álvarez Jonte on 19 August 1813. Posadas served in this capacity until the Assembly concentrated executive power in a single person in January 1814, marking the end of the Triumvirate's functions.

Transition to Supreme Director. The Assembly of Year XIII decided to replace the Triumvirate with a one-person Supreme Director. Consequently, the Triumvirate ceased its functions on 22 January 1814. Gervasio Antonio de Posadas assumed control as the first Supreme Director of the United Provinces of the Río de la Plata, taking office on 31 January 1814.
