John I of England

John I of England, also known as King John (reigned 1199–1216), was a monarch whose rule was marked by conflicts with France, powerful nobles, and the Church. He faced significant challenges maintaining his authority, leading to the signing of the Magna Carta in 1215, a historic document that limited royal power and laid foundations for modern legal rights. Despite his efforts to strengthen control, his reign ended poorly, with losses of territory and internal strife, ultimately contributing to his nickname "Bad King John." His reign significantly impacted the development of constitutional principles in England.
