The Fengu people (in the Xhosa language "Mfengu" and plural "amafengu") refers to a variety of ethnic groups that fled from the Mfecane to enter into various Xhosa speaking areas, but now often considered to have assimilated by the Xhosa people whose language they now speak. The term derives from the verb "ukumfenguza" which means to wander about seeking service. Historically they achieved considerable renown for their military ability in the frontier wars.
