Eleanor joined her husband Louis VII on the 2nd Crusade. Her son Richard the Lionhearted led the 3rd Crusade, along with Philip II (who’s also in the play). Eleanor’s great-grandson, St. Louis, launched the 7th and 8th Crusades. In NEXUS the Crusades are personalized by teaching them in connection with characters in the play.
Feudalism, which is usually taught as an abstract concept, is made concrete and personalized in the Lion volume by linking it to the central conflict of the play, which is inherently feudalistic and underscores the role of medieval noble women in feudal society, a role that Eleanor of Aquitaine continually undermined.
The 1st known coat of arms belonged to Eleanor’s father-in-law, Geoffrey Plantagenet (who is mentioned several times in the play). Richard the Lionhearted’s blazonry—three ramping golden lions on a field of red—became the royal coat of arms of England. Eleanor’s 1st husband, Louis VII, introduced the fleur-de-lys to France.
Eleanor’s son John signed the Magna Carta (and, of course, he’s the evil prince in Robin Hood).
