In 1497, Pope Alexander had a crisis of his own making that was threatening to undermine his ability to govern the Catholic Church. A romantic rivalry between two of his sons (he had at least six children) had become a source of intrigue around Rome. In fact, this scandal was so lurid, it was appalling even to those accustomed to flagrant immorality from the papacy.
The two sons in question were Cesare and Juan, and they were both in love with their sister, Lucrezia. The plot thickened, as the Pope refused to let either of his sons marry his daughter, as he was sleeping with her himself. As the famous biographer and historian William Manchester wrote, “Even for those times, this was scandalous.”
