After his father's death, Lorenzo de' Medici takes control--Golden Age of Florence

Excerpts from Books and Wikipedia

Lorenzo was a patron of artists, scholars, and inventors including Botticelli, Leonardo da Vinci, and Michelangelo. [Furtado: 1001 Days] "The Medici family rises to prominence in Florence [1434]. This ushers in a period of significance of the Medicis, such as bankers, popes, queens (regents) and dukes, throughout Europe (mainly Italy, especially the Florentine Republic), over the next three centuries."
