"King John" by William Shakespeare is a history play written in the mid-1590s about the turbulent reign of King John of England. When France demands John surrender his throne to his nephew Arthur, a succession crisis erupts into war. Amid battles, political betrayals, and papal intervention, loyalties shift between England and France. As nobles defect, family members die, and a foreign prince invades, John faces enemies from all sides—including threats from within his own kingdom. (This is an automatically generated summary.)
