Warlord

A warlord is a person with power who has both military and civil control over a subnational area due to armed forces loyal to the warlord and not to a central authority. The term can also mean one who espouses the ideal that war is necessary, and has the means and authority to engage in war. Today, the word has a strong connotation that the person exercises far more power than his official title or rank legitimately permits. Under feudalism, by contrast, the local military leader may enjoy great autonomy and a personal army, and still derive legitimacy from formal fealty to a central authority.
