Geoffrey IV
Geoffrey IV., Duke of Anjou, known as Plantagenet from his adoption of the genista or broom as his badge, was born in 1113. He married Maud, daughter of Henry I. of England and widow of the Emperor Henry V. He maintained a long and fruitless struggle with Stephen for the possession of Normandy, but his son Henry founded the Plantagenet dynasty in England. Geoffrey died in 1150 on his return from the crusade in which he had joined Louis VII.
