Geoffrey was the elder son of Fulk V of Anjou and Ermengarde of Maine. Geoffrey received his nickname from the yellow sprig of broom blossom he wore in his hat. The chronicler John of Marmoutier described Geoffrey as handsome, red haired, jovial, and a great warrior. King Henry I of England, having heard reports on Geoffrey's talents and prowess, sent legates to Anjou to negotiate a marriage between Geoffrey and his daughter, Matilda. Consent was obtained from both parties, and on 10 June 1128 the fifteen-year-old Geoffrey was knighted in Rouen by King Henry, in preparation for the wedding.
Marriage
Geoffrey and Matilda's marriage took place in 1128. The marriage was meant to seal a lasting peace between England, Normandy and Anjou. She was eleven years older than Geoffrey, and very proud of her status as dowager Empress, and which she kept for the remainder of her life. Their marriage was a stormy but happy one with frequent long separations; she bore him three sons and survived him by over 15 years.
Count of Anjou
The year after the marriage Geoffrey's father left for Jerusalem, leaving Geoffrey behind as count of Anjou. When his father in law, King Henry I of England died in 1135, Geoffrey supported Matilda in entering Normandy to claim her rightful inheritance. The border districts submitted to her, but England chose her first cousin Stephen of Blois for its king, and Normandy soon followed suit. The following year, Geoffrey gave Ambrieres, Gorron, and Chatilon-sur-Colmont to Juhel de Mayenne, on condition that he help obtain the inheritance of Geoffrey's wife. In 1139 Matilda landed in England with 140 knights, where she was besieged at Arundel Castle by King Stephen. In the 'Anarchy' which ensued, Stephen was captured at Lincoln in February 1141, and imprisoned at Bristol. A legatine council of the English church held at Winchester in April 1141 declared Stephen deposed and proclaimed Matilda "Lady of the English". During 1142 and 1143, Geoffrey secured all of Normandy west and south of the Seine, and, on 14 January 1144, he crossed the Seine and entered Rouen. He assumed the title of Duke of Normandy in the summer of 1144. In 1144, he founded an Augustine priory at Château-l'Hermitage in Anjou. Geoffrey held the duchy until 1149, when he and Matilda conjointly ceded it to their son, Henry, which cession was formally ratified by King Louis VII of France the following year. Geoffrey also put down three baronial rebellions in Anjou, in 1129, 1135 and 1145–1151. He was often at odds with his younger brother, Elias, whom he had imprisoned until Elias died in 1151. The threat of rebellion slowed his progress in Normandy, and is one reason he could never intervene in England. Geoffrey died later the same year, aged 38, and Henry took his father’s place as head of the Plantagenet ducal house. In 1153, the Treaty of Wallingford stipulated that Stephen should remain King of England for life and that Henry, the son of Geoffrey and Matilda should succeed him, beginning the Plantagenet era in English history.
Death
Geoffrey died suddenly on 7 September 1151. According to John of Marmoutier, Geoffrey was returning from a royal council when he was stricken with fever. He arrived at Château-du-Loir, collapsed on a couch, made bequests of gifts and charities, and died. His wife and sons outlived him. He was buried at St Julien's Cathedral in Le Mans France, and his son Henry succeeded him as Duke of Normandy.
Legacy
Children
Geoffrey and Matilda's children were:
Henry II, King of England, succeeded his father as head of Angevin Dynasty, had 8 children with Eleanor of Aquitaine, who became rulers of the Angevin Dynasty after their father.
An enameleffigy commissioned by his widow to decorate the tomb of Geoffrey of Anjou is one of the earliest examples of European heraldry. Jean de Marmentier, a late-12th-century chronicler, reported that in 1128 Henry I of England knighted his son-in-law Geoffrey and granted him a badge of gold lions. A gold lion may already have been Henry's own badge, and different lion motifs would later be used by many of his descendants. The enamel shows Geoffrey with a blue shield depicting gold lions, apparently the same motif later used by a grandson of Geoffrey, William Longespee. In addition to being one of the first authentic representations of a coat of arms, according to British historian Jim Bradbury it "suggests possible evidence for the early use of what became the English royal arms".
