The greatest and most loyal knight ever was William Marshal. He outlived his enemies, amassed great landholdings and titles, and married a woman he loved. He managed it all while serving a family that makes Game of Thrones and Empire seem tame.
William was born around 1147 during the civil war between Stephen of Blois and Empress Matilda. Both were grandchildren of William the Conqueror and both claimed the English throne. William’s father, John Marshal, supported Matilda which was a lucky break when her son was designated as Stephen’s heir.
