insurgence

Insurgence, or insurgency, refers to organized opposition to a government or occupying power that seeks political change through prolonged, often irregular means. The term derives from the Latin insurgere, "to rise up," and entered English via French insurrection or insurgence. In scholarly and policy discourse, an insurgency is typically characterized by clandestine organization, political mobilization, and the use of guerrilla warfare, sabotage, and propaganda to erode the state's legitimacy and control.

Insurgencies contrast with conventional wars by relying on asymmetrical tactics, avoiding large, set-piece battles, and aiming to win support from the local population. They often combine military pressure with political objectives, such as autonomy, independence, or regime change, and they may operate within or across borders for sanctuary and support networks. The state's counterinsurgency response emphasizes securing civilian support, intelligence, and development, balancing security with political reform to undermine the insurgents' legitimacy.

Throughout modern history, various insurgencies have shaped regional and global politics. Notable examples include the Viet Cong and North Vietnamese forces in Vietnam, the Algerian struggle for independence, the Irish Republican Army during the Troubles, the Moro insurgency in the Philippines, and contemporary movements in Iraq and Afghanistan. The term insurgence is sometimes used interchangeably with insurgency, though insurgence is less common in scholarly literature; both describe movements challenging established authority through sustained, nonlinear warfare.
