Supreme Director of the United Provinces of the Río de la Plata
The Supreme Director (Spanish: Director Supremo de las Provincias Unidas del Río de la Plata) served as the chief executive officer of the United Provinces of the Río de la Plata. This political office was established in 1814 by the Asamblea del Año XIII (Assembly of Year XIII), a constitutive body tasked with organizing the new government during the struggle for independence.
The creation of this role was a strategic response to the political instability of the era. By consolidating executive power, the assembly aimed to effectively confront royalist forces, who had gained momentum due to internal conflicts and dissension within the patriotic factions.

Governance and Checks on Power
To ensure stability and prevent the abuse of authority, the office of the Supreme Director was not absolute. The government structure incorporated specific checks and balances:
- Term Limits: The Supreme Director was appointed to serve a term of two years.
- State Council: The executive functioned in combination with a state council consisting of nine members.
- Legislative Oversight: The Director was required to answer to a congress, which held the primary power to enact legislation.
The Fall of Centralism and the Transition to Federalism
The era of centralism—a system where power is concentrated in a single national authority—came to an abrupt end following the unitarian defeat at the Battle of Cepeda. This military loss led to the resignation of José Rondeau.
In the immediate aftermath, Juan Pedro Aguirre briefly assumed the office. He endorsed the Buenos Aires Cabildo to appoint a governor for the province of Buenos Aires. On February 16, 1820, the national congress dissolved itself, effectively terminating the centralist government.
This collapse paved the way for a federal reorganization of the country, which was formally established by the Treaty of Pilar on February 23, 1820. According to traditional liberal historiography, such as the works of Bartolomé Mitre, this period of dissolution led to the Anarquía del año 20 (Anarchy of the 1820s). Consequently, no central authority existed among the Argentine provinces until 1826.
