Montezuma welcomed in Quetzalcoatl’s men with open arms, but Hernan Cortes seized power of the empire by using Montezuma as a figurehead against his will, while Cortes made all the real decisions. Cortes acted as a secret leader until 1520, when events caused tension to escalate, and Cortes demanded Montezuma command his people obey the Spaniards. The Indians didn’t like this at all, and showered their leader in stones, he then went on to die days later in June of 1520.
