Thierry of Alsace in the context of "William Clito"

William Clito (25 October 1102 – 28 July 1128) was a member of the House of Normandy who ruled the County of Flanders from 1127 until his death and unsuccessfully claimed the Duchy of Normandy. As the son of Robert Curthose, the eldest son of William the Conqueror, William Clito was seen as a candidate to succeed his uncle King Henry I of England. Henry viewed him as a rival, however, and William allied himself with King Louis VI of France. Louis installed him as the new count of Flanders upon the assassination of Charles the Good, but the Flemings soon revolted and William died in the struggle against another claimant to Flanders, Thierry of Alsace.
