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 (if any) 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.
