When did Argentina become a republic?

Argentina became a republic through a gradual process that began with the May Revolution of 1810, which marked the start of the independence movement from Spanish rule. However, it was not until the declaration of independence on July 9, 1816, that Argentina formally asserted its autonomy. The definitive establishment of Argentina as a republic was solidified with the enactment of its first constitution in 1853, following years of internal conflict and regional power struggles. This constitution laid the foundation for the modern Argentine Republic, with a federal system of governance that has endured, albeit with amendments over time.
