Why did the Mayan civilization suddenly disappear?

Maya civilization was born around the tenth century BC, and flourished in Central America such as Guatemala and southern Mexico today, reaching its climax in the ninth century. Mayan civilization is strange to many people. At that time, when the productivity conditions of Central American Indians were underdeveloped, the Mayans created a highly developed spiritual civilization and material civilization. They are highly prosperous in astronomy, mathematics and art, and even in astronomy, they measure more galaxies than modern European astronomers. They also created exquisite hieroglyphics that people still can't explain. However, it is such a civilization with complex system and developed culture that mysteriously disappeared.

People have given many different opinions about his disappearance. Among them, there are two factors that cannot be ignored, namely, the collision of civilizations and the influence of climate. The Mayans are located in the south of Mexico, which has always been the rear of the invasion of barbaric tribes in northern and central Mexico. In the tenth century, the Toltecs in northern Mexico established a powerful city-state alliance and attacked the south many times. The wandering Chichimek also plundered the city-states in southern Maya. Although these injuries may have little impact and limited scope, for the Mayans, their military strength is not very strong, and they are still an important factor limiting the development of their civilization. Another important reason is the climate change in Central America around 10 century. The El Nino phenomenon in this period caused a large-scale drought in the originally humid areas of Central America, which was undoubtedly an important reason for the decline of Mayan culture.

It can also be seen from the prevalence of living sacrifice in the late Mayan culture that the significance of this sacrifice is to pray for a bumper harvest from the sun god. Frequent sacrifices to the living show that the problem of crop failure in this period seriously intensified social contradictions and led to internal turmoil in Mayan civilization. It was under the influence of this famine that the cultural creativity of the Mayans decreased day by day and the Mayan civilization was submerged. Subsequently, the disastrous destruction brought by western colonists to this area made Mayan culture a lost civilization. Of course, the reason for the decline of Mayan civilization may also come from within itself. In the early stage of underdeveloped productivity, the Mayans used extensive farming methods, which seriously damaged the vegetation. In addition, the wood needed for the construction of large-scale buildings later aggravated the ecological problems, caused the shortage of resources, caused a series of internal chaos and hindered the development of civilization. There are many reasons for the decline of Mayan civilization, and the above is just a simple summary of their decline.
