6. Ivan the Terrible
Ivan IV, commonly known as Ivan the Terrible, was the first Tsar of Russia, reigning from 1547 to 1584. His rule is marked by a **reign of terror** that established the foundations of the Russian monarchy through brutal tactics. Ivan was initially celebrated for his reforms and centralization of power, but his later years were marred by paranoia and violence.
He created the Oprichnina, a state policy that allowed him to execute perceived enemies and dissenters. His infamous wrath culminated in the murder of his own son in a fit of rage. Ivan’s legacy is a complex blend of innovation and brutality.
