He did receive the support of his mother, though, to assume the throne on Richard’s death. Richard had announced his nephew, [[Arthur of Brittany]], as his heir, but Eleanor gave John the support of the immensely rich and powerful Aquitaine. Arthur and the French king Philip II were defeated at Mirebeau (1202). Arthur was captured and, according to legend, murdered by John in Rouen the following year. John’s treatment of Arthur and his fellow captives alienated many of his French subjects. | He did receive the support of his mother, though, to assume the throne on Richard’s death.
