Answer:
True.
Step-by-step explanation:
Hernán Cortés (right spelling) led an expedition of Spanish troops from Cuba that landed in present-day Veracruz. He explored the region, looking for gold and any opportunities. He got in contact with the Aztecs and managed to enter the Aztec capital, Tenochtitlán. Shrewd and treacherous, he forged an alliance with tribes subjugated by the Aztecs and laid siege to Tenochtitlán. By 1521, he controlled the territories of the old empire.
