23. Charles the Bad’s Badness Goes International
To the south, Charles the Bad’s poor reputation was no better in Spain than it was in his native France. He allied with Peter the Cruel of Castile against Peter IV of Aragon in 1362, only to turn around and betray Castile the following year, by allying with Peter IV against Peter the Cruel.
Crossing somebody whose epithet was “the Cruel” was risky, and in 1378, Castilian armies invaded Navarre, forcing Charles to flee post haste. Out of allies, having betrayed them all, Charles was forced to agree to a humiliating treaty that defanged his kingdom and reduced him and his realm to Castilian clients.
