Why were the Spanish able to defeat the Native Americans so easily?

The natives knew war, but their tactics were sophomoric and based on their religious beliefs. They would not fight to kill but to capture. After capturing the army they would sacrifice them to their gods. These tactics were ignorant and allowed the Spanish to easily crush them.

Explanation:

The Spanish were able to defeat the Native Americans so easily, as they were able to leverage multiple advantages, including:

1) Creating alliances with other native tribes that were at war with the one the Spanish was trying to topple.

2) Making use of superior weaponry and defenses, including but not limited to the usage of muskets, cannons, iron armor, etc.

3) Bringing European diseases that were more harmful to the Native Populations then to themselves.

etc.
