Br. J.B. Darcy, CFC, What you don't know about the Borgia Pope: Alexander VI (1492-1503) (Catholic Insight). Quote: "Guiliano immediately began to plot with King Ferrante of Naples against the Pope. I have mentioned already that Ferrante refused to acknowledge that he held his kingdom as a fief of the Papacy. Whether he was as evil a man as history has depicted him is hard to say, but he was certainly an ambitious, treacherous person. Determined to extend his rule to parts of the Papal States, he was blocked at every turn by Alexander. To obtain the Pope's approval for his plans, he offered his granddaughter in marriage to Jofre, the Pope's grandnephew but was refused. Finally, he decided that, to make any progress, he had to get rid of his nemesis. For this purpose, to convince the rulers to depose the Pope, he began to write a series of letters to his relatives, the sovereigns of Europe, accusing Alexander of all sorts of evil conduct, particularly of obtaining the papacy by simony."[より良い情報源が必要]
