In 1536, Buenos Aires was founded by Pedro de Mendoza.
Buenos Aires is the capital city of Argentina and one of the largest cities in South America. Pedro de Mendoza, a Spanish conquistador, founded the city in 1536, but it was abandoned a few years later due to conflicts with the indigenous people and lack of resources. In 1580, Buenos Aires was refounded by Juan de Garay, and it became an important commercial and cultural center in the region. Buenos Aires played a key role in Argentina's struggle for independence from Spain in the early 19th century and has since been a hub of politics, commerce, and culture in the country.
