Fulk IV

Fulk IV (born 1043, Château Landon, Fr.—died April 14, 1109, Angers) was the count of Anjou (1068–1109).

Geoffrey II Martel, son of Fulk III, pursued the policy of expansion begun by his father but left no sons as heirs. The countship went to his eldest nephew, Geoffrey III the Bearded. But the latter’s brother, Fulk, discontented over having inherited only a few small appanages, took advantage of the general discontent aroused by Geoffrey III’s inept rule, seized Saumur and Angers (1067), and cast Geoffrey first into prison at Sablé and later in the confines of Chinon castle (1068). Fulk’s reign then had to endure a series of conflicts against the several barons, Philip I of France, and the duke of Normandy. He lost some lands and was ridiculed when his wife, Bertrada of Montfort, took refuge with King Philip, but he secured, through battle and marriage, the countship of Maine for his son, Fulk V. An educated man, Fulk authored a unique chronicle of his family, derived largely from oral tradition and preserved only in fragments.
