La Plata was founded as the new capital of the Buenos Aires province in 1882 because the city of Buenos Aires was federalized and designated as the national capital in 1880.12

Prior to this, the city of Buenos Aires had served as the seat of both the provincial and national governments. Following the suppression of a rebellion in Buenos Aires, the long-standing dispute regarding the city's status was resolved by separating it from the province to serve as the federal territory for the nation. Consequently, provincial governor Dardo Rocha selected the site for La Plata to establish a new, dedicated administrative seat for the province.12
