The republic had a checkered history of coups and counter-coups against various factions. The Medici faction gained governance of the city in 1434, upon Cosimo de ' Medici 's counter-coup against the faction that had sent him into exile the previous year. The Medici kept control of Florence until 1494. Giovanni de ' Medici (later Pope Leo X) re-conquered the republic in 1512.
