King Richard III was born in Northamptonshire, England in 1452. Even though Richard III was king for only two years, he is one of England's most infamous rulers thanks to the lengths to which he went to gain and protect his throne.
Perhaps the most significant evidence of this is found in the way he treated his nephews—from whom he wrestled the throne. In an effort to ensure they never would come back into power, Richard III had the two boys (both no older than 12 years old) locked in the Tower of London. They remained there until they passed away, ensuring they would not be able to take Richard III's throne.
Richard III ascended to the throne in 1483. By 1485, he would be dead—having been defeated by Henry Tudor at the Battle of Bosworth. Tudor would later become King Henry VII.
