Historians cite three major reasons for the decline of the Mayan civilization:

1. Environmental Factors: One significant reason for the decline of the Mayan civilization was environmental degradation. The Mayans practiced extensive agriculture, which involved deforestation and the creation of an intricate irrigation network. Over time, this intensive land use led to soil erosion, decreased agricultural productivity, and ultimately food shortages. Additionally, prolonged droughts and climate change further worsened the ecological conditions in the region, making it increasingly difficult for the Mayans to sustain their population.

2. Political Instability: Another crucial factor contributing to the decline of the Mayan civilization was political instability. The Mayans had a complex political structure divided into multiple city-states, each governed by a ruler known as a "halach uinic." As rivalries and conflicts emerged between these city-states, wars became frequent. The constant warfare and internal power struggles weakened the overall Mayan civilization, draining resources, disrupting trade networks, and leading to social unrest.

3. Economic Decline: Economic collapse played a significant role in the downfall of the Mayan civilization. The Mayans heavily relied on trade, both inland and across long-distance routes, to obtain essential goods and resources. However, as political instability and environmental pressures soared, trade networks disintegrated, obstructing the flow of vital resources. The declining economic opportunities further catalyzed social unrest, reduced the ability to sustain the population, and ultimately contributed to the civilization's decline.

It is worth noting that these factors are not exclusive, and multiple interconnected causes likely contributed to the decline of the Mayan civilization.
