Spanish colonial rule over the Río de la Plata region had been weakening since the May Revolution of 1810. Ongoing conflicts, including the exclusion of the Federal League provinces at war with the United Provinces, created political urgency for the colonial territories to formally assert sovereignty and consolidate their independence movement.
On July 9, 1816, the Congress of Tucumán declared the independence of the United Provinces of South America, the entity that would become the Argentine Republic. Delegates from various provinces, including some from Upper Peru, convened in the city of Tucumán to formalize the break from Spanish imperial authority.
The declaration established the legal foundation for Argentine statehood under the name United Provinces of South America. Provinces of Upper Peru represented at the Congress later became part of present-day Bolivia, reflecting the fluid territorial boundaries of the post-colonial era in the region.
