Mayan cities began around 700 BC with populations around 5 to 50 thousand people. Mayans were very civilized, they had many achievements like making rubber before there was vulcanization, a complete writing system, and a 365 day calendar just to name a few.

There are several theories that lead to the Mayan's civilization to fall.There are disease, warfare, famine, and environmental change. These are the theories that lead the Mayan's civilization to fall.
Disease is the theory I think lead to the Mayan's civilization to fall. Yellow fever might have come to the Americas in the 1500s, but "plant hopper" disease was going around at the time. The "Plant Hopper" disease comes from a bug called Peregrinus maidis, and this bug hops on the crops spreading this disease.
