17. Cesare died horribly, after losing his temper one too many times
People were so scared of Cesare that whole cities sometimes surrendered without a shot being fired. But just as he set his sights on Tuscany, where he could become an independent prince, Alexander VI died. The next pope was a Borgia nemesis who made Cesare surrender all his conquered cities and threw him in prison. He escaped but was rearrested and taken to Spain. There he escaped again, and joined his brother-in-law (the King of Navarre)’s army. Besieging the castle of Viana, Cesare was furious to see several enemy knights escaping. He foolishly gave chase alone, and was butchered.
