Queen Juana and King Phillip II
Like the Spanish conquistadors that had served the Spanish king in the conquest of Mexico, the Tlaxcalans requested privileges from the king in recognition of their services as allies of Hernán Cortés. Throughout the following centuries, the Tlaxcalans continued to fight to maintain their status, reminding the crown of their loyalty and merits in assisting the Spaniards.
