An independent city or independent town is a city or town that does not form part of another general-purpose local government entity (such as a county).
In a modern context, recognized great powers came about first 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. A great power is a nation or state that, through its great economic, political and military strength, is able to exert power and influence over not only its own region of the world, but beyond to others.
The historical term "Great Nation", distinguished aggregate of people inhabiting a particular country or territory, and "Great Empire", considerable group of states or countries under a single supreme authority, are colloquial; use is seen in ordinary historical conversations (historical jargon).
