A yellow sprig of broom blossom, known in French as the genêt, likely provided the origin for the epithet Plantagenet that would eventually define a three-hundred-year royal dynasty in England. Geoffrey, Count of Anjou, adopted this emblem during his knighting ceremony in 1128, long before the moniker was applied to his descendants who claimed the English throne.
Political Alliances and Marriage
Born in 1113 as the elder son of Fulk V of Anjou and Ermengarde of Maine, Geoffrey emerged as a central figure in 12th-century European power dynamics. On 10 June 1128, King Henry I of England knighted the fifteen-year-old in anticipation of his marriage to the monarch's daughter, Matilda. This union sought to stabilize the volatile relationships between England, Normandy, and the County of Anjou, though the marriage was marked by frequent separations and significant political tension.

Following his father's departure for Jerusalem in 1129, Geoffrey assumed the title of Count of Anjou. When King Henry I died in 1135, Geoffrey focused his efforts on securing Matilda’s claims to the English throne and the Duchy of Normandy against her cousin, Stephen of Blois. Between 1142 and 1143, he systematically captured territories west and south of the Seine. In 1144, he crossed the river to enter Rouen and formally assumed the title of Duke of Normandy, holding the duchy until he ceded it to his son, Henry, in 1149.
Governance and Legacy
Geoffrey’s tenure as an aristocrat involved constant military suppression of baronial rebellions within Anjou, occurring in 1129, 1135, and during a prolonged period between 1145 and 1151. His rule was also marked by personal friction with his brother, Elias. Despite these local challenges, his marriage laid the foundation for the future reign of his son, Henry II. Geoffrey died suddenly from a fever at Château-du-Loir on 7 September 1151, and his remains were interred at Le Mans Cathedral.
Early Heraldry
An enamel funerary plaque commissioned by Matilda serves as one of the earliest documented instances of European heraldry. The artifact depicts Geoffrey carrying a blue shield adorned with gold lions. This specific imagery is considered by historians to be an early precursor to the development of the English royal arms, linking the Angevin house to the visual language of later monarchs.
