What was the capital of Argentina before Buenos Aires?

Before Buenos Aires became the capital of Argentina, the city of Córdoba served as the capital during the early colonial period. Córdoba was the political and cultural center of the region in the 16th and 17th centuries, particularly due to its strategic location and the establishment of several universities. However, in the early 19th century, Buenos Aires was designated as the capital, reflecting its growing importance and influence in the country.
