Ivan IV, also known as Ivan the Terrible, was Tsar of Russia from 1547 to 1584. His reign was marked by both expansion and brutality, including the execution of his own son, Ivan. He ascended the throne at a young age, navigating a complex world of court intrigue and power struggles. He ruthlessly consolidated power, often through violence and fear. His paranoia deepened with time, leading to the infamous oprichnina, a secret police force that terrorized the nobility and spread fear throughout the land. Ivan IV’s cruelty reached its peak when, in a fit of rage, he struck his son, Ivan, with a staff, leading to his death. This act solidified Ivan’s reputation as a tyrant and a cautionary tale of power’s corrupting influence. The event continues to be a source of fascination and horror for historians and the public alike, offering a glimpse into the dark side of absolute power.
