Edit: Here are some great videos on Mayan History off youtube, from Kings and Generals. The three-part mini series does a great job laying out the history in a quick snapshot! Rise of Mayan Civilization: Mayan Star War: Tikal versus Calakmul: Fall of Maya Civilization:
Editted the previoius post to include all three excellent videos from Kings and Generals. Great stuff, they have a lot of other great videos on other civilizations and empires through history.
For the classic Mayan collapse (~900AD) it was several factors, but here are some of the big ones I am aware of: Ecological collapse and soil erosion caused by constant overuse of good farmlands Drought, causing widespread famine and compounding the environmental issues Constant warfare between competing city states and the elites Possible rebellion, caused by all of the above factors, and further eroding the central power of the kings and elite rulers
It is interesting and curious that civilization seems to have had a tougher time getting going / rebuilding in the Americas. Aztecs Incas Last two left standing.
I don't know as much about the Aztec or Incas unfortunately. Unlike either of these two groups, the Maya were never a "united empire" of the like of the other two. While this meant they didn't have a large jungle-spanning empire at the arrival of the Spanish (as they existed in small, competing tribal groups spread out over a large jungle area), this also meant they were much more difficult for the Spanish conquisadors to conquer, as they had no single ruler or center of gravity that could be easily captured, destroyed, or held for ransom. Fortunately Kings and Generals has a few more videos! Aztecs: Incas:
Photos and artwork from the city of El Mirador, home to some of the largest pyramids in the New World Spoiler: El Mirador
Aztec Xiuhmolpilli: symbolic mark for the completion of the 52 year cycle. This one was labelled as "Naissance de Ce Actal Topiltzin Quezacoatl." Don't know if it is Aztec or not.
Definitely looks more Aztec to me than Mayan. But then... might be something else as well. I am still no expert despite looking at thousands of pictures of mesoamerican stuff.
Found a short video on the importance of WATER to ancient civilizations. Highlighted civilizations are the Mayans and another jungle civilization, the Khmer of the 12th century.
Fall of Tenochtitlan Epic Aztec diorama, terrain, and beautifully painted miniatures. Lots more pics here. Rack of skulls!
