What is a likely reason for the decrease in stability for societies that rely on external control?

Societies that rely on external control often experience a decrease in stability due to a lack of internal cohesion and resilience. When governance is imposed from outside, it can lead to feelings of alienation and resentment among the population, undermining trust in institutions. Additionally, dependence on external forces can stifle local initiative and adaptability, making communities more vulnerable to disruption. This combination can result in social fragmentation and increased unrest.
