Cornelio Judas Tadeo de Saavedra y Rodríguez was a military officer and statesman from the Viceroyalty of the Río de la Plata. He was instrumental in the May Revolution, the first step of Argentina's independence from Spain, and was appointed president of the Primera Junta.
Saavedra was the first commanding officer of the Regiment of Patricians created after the ill-fated British invasions of the Río de la Plata. The increased militarization of the city and the relaxation of the system of castas allowed him, as other criollo peoples, to become a prominent figure in local politics. His intervention was decisive to thwart the Mutiny of Álzaga and allow viceroy Santiago de Liniers to stay in power.
