Civil War

A civil war is a large-scale armed conflict within a single country, typically between the established government and opposing groups, or in failed states without recognized authority, among warlords or communal factions. It can be driven by struggles for state control, secessionist movements, or external proxy influences, and often involves intra-elite rivalries. Variants include secessionist wars, revolutionary guerrilla warfare, conflicts between military and civilian authorities, criminal gang wars, terrorist campaigns, religious or fundamentalist movements, genocidal campaigns and ethnic cleansing, state-society conflicts, territorial disputes between peoples or nations, factional clashes within parties or armed forces, inter-communal conflicts among religious, ethnic, linguistic, tribal, or clan groups, wars between nomadic and sedentary populations, and clashes between immigrants and natives.
