Lu Bu (- February 199 CE); courtesy name Fengxian; was a notorious military general and warlord who lived during the time of the Three Kingdoms. He was infamous for serving and betraying various minor warlords; defecting from one to another with increasing regularity. He managed to take over Yan Province from warlord Cao Cao in 194 CE; but lost it in less than two years. Offered refuge in Xu Province by Liu Bei; Lu Bu in turn betrayed his new benefactor; seizing control of the province from his host.

He formed but quickly broke an alliance with Yuan Shu; after the latter declared himself 'Emperor'; an act of treason against the true Han emperor; and joined forces with Cao Cao and others in attacking the pretenders. He sided with Yuan Shu again in 199 CE though; and was eventually punished for his numerous betrayals by the combined forces of Cao Cao and Liu Bei; resulting in his final defeat in 199 CE; where he was captured and executed by Cao Cao.

Lu Bu is historically and fictionally described as an incredibly fearsome warrior marred by his temperamental behaviour; switching allegiances without warning and guiltlessly betraying his erstwhile allies. His life and achievements are dramatised in the famous historical novel; 'The Romance of the Three Kingdoms'; which portrays him as warrior unmatched in his skill and ruthlessness; lacking any morals.
