How has the concept of sovereignty changed over time?

Sovereignty refers to the ability of the state to act independently on world stage granting authority to rule itself. Over time, due to the growth of civil society and the expansion of international organizations has led to a condition of pooled sovereignty for many states. As a result, states have transferred certain powers from national governments to international institutions, such as the EU, which in turn exert a higher degree of influence on sovereign states. Hence, it can be argued that the concept of state sovereignty has evolved into one of pooled sovereignty, in which certain powers are shared between the state and civil society.
