How did a small Spanish Army conquer the Aztecs?

A small Spanish army of 900 conquered the Aztec civilisation of 200,000 in 1519-1521. The small army had only 600 and then 300 reinforcements. They did this with the help of their better weapons and resources. They also had smarter strategies, which with the Aztec mistakes and a few accidental factors allowed them to overpower the Aztecs.

The Spanish had a wide variety of weapons and resources which helped them to take over the Aztec civilisation. The Spaniards had guns and horses. This gave them an enormous advantage over the Aztecs, who were fighting on the ground, on foot with wooden weapons. The Aztecs only had wooden lances tipped with stone and cane shields, whereas the Spaniards had steel weapons and shields.
