Why was Cortes and his men were able to conquer the Aztec capital Tenochitilan prtly because?

Answer 1

The Aztecs were brutal. They ruled over many different people who were willing to join a revolt but none of which had the ability to lead a revolt. When Cortez and his puny army attacked, they were joined by an indigenous army many times larger than that of the Aztecs. Since the capital stood on an island, it was easily defended. In spite of the size of the opposing army, the Aztecs held out for quite a while. Gradually the siege came closer and closer and the masses overwhelmed their masters. The great mob turned the city to rubble. Cortez cried. That was not what he had wanted. He wanted the great architecture to remain. He had seen the great cities of Europe. There had never been a city like Tenochitilan.
