Quick Summary

Manuel Dorrego was a key figure in early 19th-century Argentine politics, serving as the governor of Buenos Aires. He was a federalist, aligning with landowners and political spokesman Juan Manuel de Rosas. Dorrego made peace with Brazil, leading to the independence of Uruguay, a territory previously considered vital to Argentina's national integrity. His governorship was cut short when troops overthrew him in December 1828, and he was subsequently executed. This event fueled further political conflict, with Rosas eventually rising to power as governor with dictatorial authority.12
