Political map of North America & the Caribbean 8 November 1519 (March to Tenochtitlan): Persuading the people of Cempoala (Veracruz) and Tlaxcala to align with him, Cortés (Hernán Cortés) expanded his army and marched inland toward the Aztec capital of Tenochtitlan. Passing through the city of Cholula (Cholula (Mesoamerican site))—which the Spaniards sacked when they suspected an ambush (Cholula massacre)—Cortés reached Tenochtitlan in November, to be reluctantly greeted as a guest by Emperor Moctezuma II.
