Geoffrey II, called Martel, was Count of Anjou from 1040 to 1060 and Count of Vendôme from 1032 to 1056. He was the son of Fulk the Black. He was bellicose and fought against William VII, Duke of Aquitaine, Theobald I, Count of Blois, and William, Duke of Normandy. During his twenty-year reign he especially had to face the ambitions of the Bishop of Le Mans, Gervais de Château-du-Loir, but he was able to maintain his authority over the County of Maine. Even before the death of his father in 1040, he had extended his power up to the Saintonge, where he founded the Abbey aux Dames. Geoffrey Martel and his wife Agnes also founded the Abbaye de la Trinité at Vendôme. The first mention of Geoffrey in the Gesta Normannorum Ducum reads: "Geoffrey, count of the Angevins, nicknamed Martel, a treacherous man in every respect, frequently inflicted assaults and intolerable pressure on his neighbors." "In alliance with King Henry I of France, Count Geoffrey laid siege to Tours in the winter of 1042–3. After the battle of Nouy on 21 August 1044 Count Theobald I of Blois-Chartres was taken prisoner by , to whom he surrendered Tours with Chinon and Langeais, excluding, however, the monastery of Marmoutier." Henry and Geoffrey became estranged after this, and were not reconciled again until c. 1052, when their names appear together in a charter of August of that year. This is in conjunction with the rebellion of William of Talou against the duke of Normandy, and Count Geoffrey's taking possession of the city of Mans. Allied once again with King Henry, Count Geoffrey assaulted Normandy and seized the towns of Domfront and Alençon, evidently with the help of treachery within. Duke William laid siege to Domfront, which resisted his efforts to retake it throughout the winter of 1052. At this point Talou withdrew from the siege and started his rebellion. Duke William rapidly retook Alençon and then Domfront, driving Count Geoffrey back across the Norman border into Maine. While Count Geoffrey was off balance, Duke William laid siege to Talou's castle at Arques. King Henry failed to relieve Arques, and Talou's rebellion had failed and he was exiled by late 1053. In late January, early February 1054, Count Geoffrey and King Henry together invaded Normandy and marched down the Seine toward Rouen. The King had divided his army and sent the other wing through eastern Normandy under the command of his brother Eudes, supported by Count Reginald of Clermont, Count Ralph of Montdidier, and Guy I, Count of Ponthieu. This army was defeated in a battle near Mortemer. Upon learning of this reverse, King Henry insisted upon retreating from Normandy, and Count Geoffrey accompanied him. For the next several years, the war was centered in the County of Maine, with Duke William on the offensive. But King Henry in 1057, "burning to avenge the insult inflicted on him by the duke, summoned Geoffrey, count of Anjou, to prepare a large army for another expedition into Normandy." This combined effort placed Duke William temporarily on the defensive. He retreated before the invaders as they moved deeper into Normandy. After penetrating to the Bessin, the Franco-Angevin army began to ford the River Dives near the estuary which is tidal. After the king and Count Geoffrey had crossed over, the remainder of their army got stuck on the opposite bank by the incoming tide. Duke William launched a sudden attack and defeated them. King Henry and Count Geoffrey withdrew again from Normandy and never returned. Count Geoffrey continued to offer resistance in Maine against the Norman expansion until his death on 14 November 1060.
Family
An unusual entry in the cartulary of Ronceray describes a dispute over a vineyard seized by Geoffrey Martel and granted to his "wives, or rather concubines", Agnes, Grécie, Adele, and Adelaide. Whether these women were his wives or concubines, each relationship can be described. Geoffrey II's first wife was Agnes of Burgundy, the widow of William V, Duke of Aquitaine; she and Geoffrey married in 1032, but had divorced by 1050. His second wife was Grécie of Langeais. Geoffrey II dismissed her to marry Adèle, the daughter of a "Count Odo", perhaps Odo II, Count of Blois. He also divorced Adèle, and took Grécie back as his wife. His last wife was a German woman named Adelaide. Despite these marital escapades, Geoffrey died childless. He became a monk in Saint-Nicolas d'Angers in 1060.
Succession
He was the last member of his paternal House to rule Anjou. He was succeeded by his distaff nephew Geoffrey IIIof the House of Gâtinais.
