Eleanor supported a revolt by her children against their father's rule in 1173. This revolt was unsuccessful, and King Henry II was so furious that he locked her away in a prison. In 1189, after King Henry II died and her son, Richard, came to be the king, Eleanor was freed. Shortly after, Richard died so she supported her son John to take the English throne against the claim of her grandson Arthur of Brittany. In 1202 during the campaign at Mairebeau, she continued to thwart Arthur. Emerging triumphant, Eleanor retired to a monastery. She died there on April 1, 1204.
