The Aztec had numerous achievements. They were able to create finely made stone pyramids and statues. They were able to use gold, gems, and bright feathers to make beautiful jewelry. Also, they studied astronomy, and were able to make a calendar from it much like the Mayans did. In addition, they kept very detailed history records since they had a lot of pride in their history. Not only that, but their oral traditions about ancestors or gods were kept alive for many years, in fact, some are still told today.
