Question

Why did empires fall? ​

Answer 1

Global history has taken a boost from the current conflicts, protests and riots against corporate globalisation, and the threat of worldwide terrorism against the West. These events fit into a global pattern of the rise and fall of societies, that can be traced back to ancient times.

Answer 2

When historians say that an empire fell, they mean that the central state no longer exercised its broad power. This happened either because the state itself ceased to exist or because the state's power was reduced as parts of the empire became independent of its control.
