Paul I of Russia
Paul remained overshadowed by his mother for most of his life. His reign lasted four years, ending with his assassination by conspirators. He adopted the laws of succession to the Russian throne—rules that lasted until the end of the Romanov dynasty and of the Russian Empire. He also intervened in the French Revolutionary Wars and, toward the end of his reign, added Kartli and Kakheti in Eastern Georgia into the empire which was confirmed by his son and successor Alexander I.
Michael Corleone
John Paul I dies soon after being elected pope, poisoned by Gilday. Michael learns that Altobello (in league with the conspirators) has hired an assassin named Mosca to kill him. Mosca murders Tommasino, and Michael vows before his old friend's casket to sin no more. Vincent reports that Lucchesi, working with Altobello, is behind the assassination attempts on Michael.
