Warlord is a term that refers to a person with power who has de facto military control of a subnational area, due to armed forces loyal to the warlord and not to a central authority; the word has a strong connotation that the person exercises far more power than his official title or rank (if any) legitimately permits him. Under feudalism, in contrast, the local military leader may enjoy great autonomy and a personal army, but still derives legitimacy from formal fealty to a central authority.
"Warlordism" was coined to describe chaos at the birth of the Chinese Republic (1911 - 1949) known as the Warlord Era, but can be used to describe similar periods in other countries or epochs such as in Japan during the Sengoku period, or in China during the Three Kingdoms, or in Somalia or other failed states today (2006).
The word Warlord arose as translation from the German word "Kriegsherr" with the same meaning. Today the Germans often use the English word, which has overtaken "Kriegsherr" in their language.
The Imperial commanders-in-chief during the reign of Emperor Maximilian I did hold the title Kriegsherr of which the direct translation was "warlord", but they were not warlords in the definitive sense of the word.
During most of the 16th century, before the Tokugawa era, Japan was tormented by repeated wars among rival warlords (see Sengoku Era). Each warlord had several castles, neighbouring land with peasants and a private army of samurai.
Warlords exercised widespread rule in China several times in Chinese history, notably in the period from the Xinhai Revolution when numerous provinces rebelled and declared their independence from the Qing Dynasty in 1911, and especially after Yuan Shikai's death, until the Northern Expedition in 1927 in a period known as the Warlord Era. They were dictators who only cared about the amount of territory and power they had, rather than the welfare of their people. The lack of a central government meant that during this time political corruption was rife. This is also the time when the term "warlord" first appeared. Despite the superficial unification of China in 1927 under the rule of the Kuomintang under Chiang Kai-shek, warlordism remained a problem unsolved until the victory of the Communist Party of China in 1949. The Chinese warlords are depicted in the computer game "Hearts of Iron" and its sequel "Hearts of Iron 2", which are both banned in mainland China for the depiction of warlords as independent entities separate from Nationalist China.
Another era in Chinese history well-known for the dominance of warlords is the era of the Three Kingdoms
