About Geoffrey "Mantell" Plantagenet, VI, Count of Nantes

Geoffroy d'Anjou VI

From Medlands:,%20MAINE.htm#GeoffroyVdied1151B

GEOFFROY d’Anjou (Rouen, Normandy 1 Jun 1134-Nantes 26 Jul 1158, bur Nantes). Robert of Torigny records the birth "1134 mense Maio in Pentecoste Rothomagi" of "Gaufridus secundus filius Gaufridi comitis Andegavensis", specifying that his mother "Matildis imperatrix" was "infirmata…propter difficultatem partus usque ad desperationem"[348]. The Chronicæ Sancti Albini records the birth "1134 Kal Jun" of "Gaufridus"[349]. William of Tyre names him as his parents' second son[350]. "Goffridus comes filius Fulconis regis Jerusalem" renounced rights to Angers with the consent of "filiis meis Henrico et Goffrido" by charter dated [1136/1140] which also names "uxori meæ Mathildi"[351]. His father intended him to succeed as Comte d'Anjou but his brother Henri did not permit this. Geoffroy revolted against his brother in 1152 and 1156, after which his castles of Chinon, Loudun and Mirebeau were confiscated. He was appointed Comte de Nantes by his brother in 1157 after the expulsion of Comte Hoël[352]. Matthew of Paris specifies that Geoffroy was the brother of King Henry II when he records his death in 1158, after which Nantes was transferred to his brother[353]. Robert of Torigny records the death "1158 mense Julio" of "Gaufrido comite Nannetensi fratre Henrici regis Julio"[354].



Geoffrey VI (June 3, 1134, Rouen - July 27, 1158, Nantes), Count of Anjou, of Maine and Nantes from 1156 to 1158, was the son of Geoffrey V, Count of Anjou and Empress Matilda.

It was said that in his will, Geoffrey V had stipulated that his second son Geoffrey would become Count of Anjou and of Maine if his elder son Henry managed to become King of England. In the meantime, he granted Geoffrey the castles at Chinon, Loudun, Mirebeau and one other castle. The body of the count would remain unburied until Henry agreed to the terms of the will. The story was reported in contemporary sources only in a minor chronicle in Tours; W. L. Warren makes the case that the story was invented by Geoffrey.[1]

In 1154, Henry acceded to the English throne. Henry had a claim to some parts of Anjou and Maine through his marriage to Eleanor of Aquitaine. Between 1156 and his death in Nantes on July 27, 1158, Henry and Geoffrey ruled Anjou jointly.

If successful the five of them intended to divide the lands of Henry and Eleanor amongst themselves.
