Final answer:
The Aztec initially reacted to the Spanish with curiosity and welcoming, but the relationship quickly turned into conflict.
Step-by-step explanation:
The Aztec initially reacted to the Spanish with curiosity and welcoming. When the Spanish soldiers, led by Hernán Cortés, arrived in the Aztec Empire, the Aztec emperor, Moctezuma II, believed that the Spanish may be gods or messengers of the gods. He sent them gifts and allowed them to enter their capital city, Tenochtitlán, peacefully. However, this initial trust quickly turned into conflict when the Spanish began to take control and impose their rule on the Aztecs.
