Geoffrey Plantagenet, also known as Geoffrey V, was a renowned warrior and nobleman who played a significant role in the establishment of the Plantagenet dynasty in England.
Born on August 24, 1113, in Anjou, France, he inherited the titles of Count of Anjou, Touraine, and Maine in 1129.
Later in 1144, he also became the Duke of Normandy through conquest. In this article, we will explore the life and achievements of Geoffrey Plantagenet.
Early Life of Geoffrey Plantagenet
Geoffrey was the eldest son of Fulk V of Anjou and Ermengarde of Maine. He received his nickname “Plantagenet” from the broom blossom sprig he wore in his hat.
According to the chronicler John of Marmoutier, Geoffrey Plantagenet was a handsome, red-haired, and jovial warrior who possessed remarkable talent and prowess.
Marriage to Empress Matilda
King Henry I of England, having heard of Geoffrey’s military prowess and accomplishments, sent emissaries to Anjou to negotiate a marriage between Geoffrey Plantagenet and his daughter, Empress Matilda.
In June 1128, they married to seal a lasting peace between England, Normandy, and Anjou.
Though Matilda was eleven years older than Geoffrey, they had a stormy but happy marriage and had three sons: Henry, Geoffrey, and William.
Count of Anjou
The year after Geoffrey’s marriage, his father left for Jerusalem, leaving him behind as the count of Anjou.
When Henry I of England died in 1135, Geoffrey supported Matilda in claiming her inheritance in Normandy.
Although the border districts submitted to her, England chose Stephen of Blois, her first cousin, as king, and Normandy followed suit.
In 1139, Matilda landed in England with 140 knights and was besieged at Arundel Castle by King Stephen.
During the ensuing Anarchy, Stephen was captured in 1141, and a legatine council of the English church declared him deposed and proclaimed Matilda “Lady of the English.”
In 1142 and 1143, Geoffrey secured all of Normandy west and south of the Seine and assumed the title of Duke of Normandy in the summer of 1144.
Geoffrey’s Legacy

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’s death in 1151.
Though the threat of rebellion slowed his progress in Normandy, he held the duchy until 1149, when he and Matilda ceded it to their son Henry. Geoffrey died suddenly on September 7, 1151, aged 38, while returning from a royal council.
He was buried at St. Julien’s Cathedral in Le Mans, France, and his son Henry succeeded him as Duke of Normandy.
Geoffrey’s contribution to the establishment of the Plantagenet dynasty cannot be overstated. His marriage to Matilda laid the foundation for his sons’ reign, beginning the Plantagenet era in English history.
Additionally, he was one of the earliest examples of European heraldry, as evidenced by an enamel effigy commissioned by his widow to decorate his tomb.
It depicted a blue shield with gold lions, the same motif later used by his grandson, William Longespee.
Conclusion
Geoffrey Plantagenet was a remarkable figure in medieval European history. He played a vital role in establishing the Plantagenet dynasty in England, and his contributions to the realm of heraldry are still relevant today.
Although he died young, his legacy lived on through his sons, who became kings of England, and his descendants, who continued to rule England for centuries.
Geoffrey’s life and achievements continue to inspire people even today, and his story is an integral part of English history.
