Contrary to popular belief,the Mayans were not united as one empire is
(A) TRUE.
The Maya lived in three separate sub areas with distinct environmental and cultural differences.The Maya civilisation was never united,rather it consisted of many small states ruled by kings,each apparently centered on a city.At times, a stronger Maya state would dominate a weaker Maya state and be able to exact tribute and labour from it.
The Maya is a Mesoamerican civilisation noted for Maya script,the only known fully developed writing system of the pre Columbian America,as well as,for its art,architecture and mathematical and astronomical systems.
The Maya had no central king ruling their big empire.Instead,there were 20 different states,similar to ancient Greece city states.
