1. A condition of revolt against a recognized government that does not reach the proportions of an organized revolutionary government.
2. An organized rebellion aimed at overthrowing a constituted government through the use of subversion and armed conflict.

An insurgency, or insurrection, is an armed uprising, or revolt against an established civil or political authority.

People who are involved with an insurgency are called "insurgents", and they usually engage in regular or guerrilla combat against the armed forces of the established government, or conduct sabotage and harassment in the country with the purpose of undermining the government's leadership position.

An insurgency is not considered to be the same as a resistance both in its political overtones and in the nature of the conflict. An insurgency refers to an internal struggle against a standing, established government; however, a resistance indicates a struggle against invading or occupying foreign forces and their collaborators.
