He murdered his nephew, inspired the legend of Robin Hood and caused the creation of Magna Carta.
Contemporary chroniclers were mostly critical of John's performance as king, and his reign has since been the subject of significant debate and periodic revision by historians from the 16th century onwards. Historian Jim Bradbury has summarised the contemporary historical opinion of John's positive qualities, observing that John is today usually considered a "hard-working administrator, an able man, an able general" Nonetheless, modern historians agree that he also had many faults as king, including what historian Ralph Turner describes as "distasteful, even dangerous personality traits", such as pettiness, spitefulness and cruelty. These negative qualities provided extensive material for fiction writers in the Victorian era, and John remains a recurring character within Western popular culture, primarily as a villain in films and stories depicting the Robin Hood legends.
Attila The Hun
Attila was Khan of the Huns. He is remembered as the epitome of cruelty and rapacity. During his reign he was one of the most feared enemies of the Western and Eastern Roman Empires. He crossed the Danube twice and plundered the Balkans, but was unable to take Constantinople. He also attempted to conquer Roman Gaul (modern France), crossing the Rhine in 451 and marching as far as Aurelianum (Orléans) before being defeated at the Battle of the Catalaunian Plains.
Bloody Mary Tudor
Mary I (18 February 1516 – 17 November 1558) was Queen of England and Ireland from July 1553 until her death. Her executions of Protestants caused her opponents to give her the sobriquet "Bloody Mary".
