 In 1513, Pope Julius II died and was succeeded by Pope Leo X, the second son of Lorenzo dei Medici.From 1513 to 1516 Pope Leo was on good terms with Pope Julius's surviving relatives, so encouraged Michelangelo to continue work on Julius's tomb, but the families became enemies again in 1516 when Pope Leo tried to seize the Duchy of Urbino from Julius's nephew Francesco Maria I della Rovere.Pope Leo then had Michelangelo stop working on the tomb, and commissioned him to reconstruct the façade of the Basilica of San Lorenzo in Florence and to adorn it with sculptures.
