How the mayans disappeared
There are many theories of how the mayans died some theories are dieing in wars famine from disease global warming and starvation but I belive warfare did not kill the mayans many mayan cities were still standing when europeans arrived if war killed them attackers would have killed the populace and burned the cities not make the populace move right outside the city after killing most of the mayans in the city.
The mayans are 1 of 3 ancient civilazations to have a complete writing system along with china and mesopatamia this help the mayans communicate better and inproved knowledge because more things could be written and read and less teachers were needed.
Although it is impossible to know what happened to the mayans may theory is that the mayans starved from over farminging with slash and burn a disease that kills maize and climate change all combining together to starve the mayans.
