Geiseric the Lame (c. 389 – January 25, 477), also spelle as Gaiseric or Genseric, was the King of the Vandals and Alans (428–477) and was one of the key players in the troubles of the Western Roman Empire in the 5th century. During his nearly 50 years of rule, he raised a relatively insignificant Germanic tribe to the status of a major Mediterranean power — which, after he died, entered a swift decline and eventual collapse.
