Lorenzo di Piero de' Medici was an Italian statesman, banker, de facto ruler of the Florentine Republic and the most powerful and enthusiastic patron of Renaissance culture in Italy. Also known as Lorenzo the Magnificent by contemporary Florentines, he was a magnate, diplomat, politician and patron of scholars, artists, and poets. As a patron, he is best known for his sponsorship of artists such as Botticelli and Michelangelo. He held the balance of power within the Italic League, an alliance of states that stabilized political conditions on the Italian peninsula for decades, and his life coincided with the mature phase of the Italian Renaissance and the Golden Age of Florence. On the foreign policy front, Lorenzo manifested a clear plan to stem the territorial ambitions of Pope Sixtus IV, in the name of the balance of the Italian League of 1454. For these reasons, Lorenzo was the subject of the Pazzi conspiracy (1478), in which his brother Giuliano was assassinated. The Peace of Lodi of 1454 that he helped maintain among the various Italian states collapsed with his death. He is buried in the Medici Chapel in Florence.
