Invasions by the Sea Peoples and internal strife, including social upheaval and conflicts, weakened political structures.

These combined factors led to the gradual decline and eventual collapse of Mycenaean society around the 12th century BCE.

The collapse of the Roman Empire was influenced by several long-term economic factors, including overreliance on slave labor, which stifled innovation and productivity. Additionally, rampant inflation devalued currency and disrupted trade, while heavy taxation strained the populace and weakened economic stability. Furthermore, the empire's vast size made it difficult to manage resources effectively, leading to regional disparities and economic decline. These factors combined to erode the economic foundation of the empire, contributing to its eventual collapse.
There is no single cause for the fall of the Maya civilization, but factors such as environmental degradation, drought, overpopulation, warfare, and social conflicts have been identified as contributing to their decline.
