Ivan III of Russia

Ivan III Vasilevich, also knows as Ivan the Great (1440-1505) was the leader of Russia during the Italian Renaissance.

Biography
During the Liberation of Rome, the Assassin Ezio Auditore da Firenze sent a team of Apprentices from the Roman Assassins Guild to Moscow to investigate the dissapearance of a fellow Assassin, Pietro Antonio Solari.

Investigations led the Assassins to another fellow Assassin, Ridolfo Fioravant, who had gone into hiding. He explained to the Roman Apprentices that Ivan was close to uncovering the truth behind their Order.

The Assassins then decided to distract the ruler by presenting him a different conspiracy to investigate. They started spreading false proof of a reemergence of the Strigolniki Sect. Through the fabricated documents, paranoia starts to spread in Moscow and Ivan sent his top agents to investigate the non-existing sect. The Assassins killed the men and carved the Strigolniki symbol in the floorboards beneath them, causing Ivan to stop investigating the Assassin Brotherhood and direct all his attention to the Strigolniki Sect.
