List of modern great powers

A great power is a nation or state that, through its economic, political and military strength, is able to exert power and influence not only over its own region of the world, but beyond to others.

In a modern context, recognized great powers first arose in Europe during the post-Napoleonic era. The formalization of the division between small powers and great powers came about with the signing of the Treaty of Chaumont in 1814.

The historical terms "Great Nation", a distinguished aggregate of people inhabiting a particular country or territory, and "Great Empire", a considerable group of states or countries under a single supreme authority, are colloquial; their use is seen in ordinary historical conversations.
