Although it is unclear how this civiliztion began it still was the most powerful Western Civilization in its time, these amzing people were absolutley wonderful workers. For example Huitzilopochtli, the Aztec God of War, lead the people to find a capital city with an eagle carrying a snake perched on cactus. After years of searching in vain the Aztecs finally found a new capital city, Tenochtitlan , which thrived until the Aztecs demise in the 1500's.
The Aztecs were amazing fighters, the Aztec Army was increasingly storng and unbeatable, until the Spanish Conquestadors arrived, but that's another story to be told, thanks to their army's exetreme power they were able to build many empires and conquer many others.
Any way you face it , The Aztecs had an amazing run, especially with their rich culture, and their amazing mythology, including many nature gods. But another great thing Aztecs are known for is the Mayan Calendar, which is viewed up above in the header, but the calendar is also mildly feared since it says the world will end in 2012, and most likely won't happen. But aside from the end-of-the-world thing it is also amazing that such an ancient civilisation can create such an amazing, and accurate, calendar!
Plus, the Aztecs were amazing astronomers, they were actually able ot predict soltisces and connected it to their own spirit passings and could predict eclipses to times of praise or even death. These people were exetremly ahead of their time, including the fact they lived so long and how long they flourished for so many years of their time.
