William Marshall was born the younger son of a minor English noble and as a result, was legally landless. His life was also chaotic; when he was only five years old his father gave him to the king as surety for a debt. While this solved some of his father's problems it was dangerous for William. Enraged that the debt was not paid in money the king sentenced the five-year old William to death by hanging. Luckily, cooler heads prevailed and William escaped the noose. He grew up to become a wealthy knight and in time, rose to the rank of Earl.
William was the consummate knight, both battle tested and a tournament champion. The model of the chivalrous knight, William was was anything but soft toward his enemies. He served five British kings, beginning with Henry II and his queen, Eleanor of Aquitaine. William's influence extended to his helping negotiate the terms of the Magna Carta. His life was never a calm one as the politics of the time required shifting alliances and a cool head.
Thomas Asbridge was able to tell William's colorful story thanks to the earthing of a 13th century biography of the knight. In 1861, a French scholar bought the volume, the only known copy, at auction and it has been kept in various private collections. This book is rich in historical detail and includes genealogical charts and maps, which add to the story.
