Eleanor of Aquitaine and Isabella of France were two exceptional medieval queens who exercised political power despite norms against women holding such influence. Eleanor inherited vast lands and married two kings, helping her sons Richard and John rule England as regent or providing diplomatic support. Isabella conspired with her lover to depose her cruel husband King Edward II, becoming the only queen to remove a English king from the throne and rule in his place alongside her son Edward III. Both women defied expectations and became highly influential figures in Europe through their strategic marriages and support of their sons' rules.
