Warlordism in Afghanistan—another state where the central government is unable to extend political, military or bureaucratic control over large swaths of territories outside the capital—functions cooperatively within the framework of the state, at times. The warlords, with their established militias, are able to maintain a monopoly of violence within certain territories. They form coalitions with competing warlords and local tribal leaders to present the central government with a challenge, and often the state will bargain to gain access to resources or "rent", loyalty from the warlord and peace in the region.
