Warlords are individuals who exercise military, economic, and political control over a region, often one without a strong central or national government, typically through informal control over local armed forces. Warlords have existed throughout much of history, albeit in a variety of different capacities within the political, economic, and social structure of states or ungoverned territories. The term is often applied in the context of China around the end of the Qing dynasty, especially during the Warlord Era. The term may also be used for a supreme military leader.
