Maya Civilization Declines

Around 900, the people eft the cities and went to the hillsides and as of now, historians don't know why

Theories include:
-Too many people, not enough food, lack of food and land because of warfare

-Kings were too demanding, some citizens may have rebelled

-Weather, 150 years of dry weather, too hard to grow crops

-Most agree that probably not one reason ended the Classic Age
