Why did Montezuma welcome Cortés? He wanted to learn Spanish.1He thought he was an Aztec god.2He wanted to trade with him.3He wanted his weapons.4

Montezuma, the Aztec emperor, welcomed Hernán Cortés, the Spanish conquistador, primarily because he believed Cortés was the reincarnation of the Aztec god Quetzalcoatl. According to Aztec prophecy, Quetzalcoatl was expected to return from the east, and since Cortés arrived from the east, Montezuma thought he was the god returning.

Here are the steps to answer your question:

1. Montezuma did not welcome Cortés because he wanted to learn Spanish. There's no historical evidence to suggest this.

2. Montezuma thought Cortés was an Aztec god, specifically Quetzalcoatl. This is the primary reason why he welcomed Cortés. The Aztecs had a prophecy that Quetzalcoatl would return from the east. Since Cortés arrived from the east, Montezuma believed he was the god returning.

3. The idea of trade might have been a factor, but it was not the main reason. The Aztecs did engage in trade with the Spanish, but it was not the primary reason for Montezuma's welcoming of Cortés.

4. Montezuma did not welcome Cortés because he wanted his weapons. The Aztecs were initially unaware of the destructive power of the Spanish weapons.
