Answer:
Natural disasters
Drought
No government
Step-by-step explanation:
These have all been suggested by experts as possible reasons for the decline of the Mayan civilization. It is possible that the Mayan cities were abandoned following a natural disaster that took place around the 10th century. However, it is unclear what this could have been. Another possibility is that of drought. This would have hit the Mayans particularly hard, as they depended on rainwater for all their needs. Finally, its is possible that alliances between cities broke down, and that priests and rulers lost their power. This would have left the cities with no government.
