Geoffrey II, Count of Anjou in the context of Gesta Normannorum Ducum

The Count of Anjou was the ruler of the County of Anjou, first granted by King Charles the Bald of West Francia in the 9th century to Robert the Strong. Ingelger and his son, Fulk the Red, were viscounts until Fulk assumed the title of count.

Ingelger's male line ended with Geoffrey II. Subsequent counts of Anjou were descended from Geoffrey's sister Ermengarde and Count Geoffrey II of Gâtinais. Their agnatic descendants, who included the Angevin kings of England, continued to hold the title and territory until King Philip II Augustus seized the region and annexed it to the French crown lands.

The House of Ingelger (French: Ingelgériens), also known as The Ingelgerians, was a lineage of the Frankish nobility, and the first dynasty in Anjou, where they established the autonomy and power of the county of Anjou between 930 and 1060. It was founded by Ingelger (died 886), Viscount of Angers, whose son Fulk the Red made himself count of Anjou. By inheritance, the family came into the possession of the county of Vendôme.

The family died out in the male line in 1060 with Geoffrey II of Anjou. He was succeeded in Anjou by his sororal nephew, Geoffrey the Bearded, son of the Count of Gâtinais.

Theobald III of Blois (French: Thibaut; 1012–1089) was count of Blois, Meaux and Troyes. He was captured in 1044 by Geoffrey II, Count of Anjou, and exchanged the County of Touraine for his freedom. Theobald used his nephew's involvement with the Norman invasion of England to gain authority over the County of Champagne. He died in 1089.
