Fan Casting William Longespée, Earl of Salisbury in Robin Hood and the House of Plantagenet (TV-Series)

Illegitimate son of the late King Henry II of England and his mistress Ida de Tosny, half-brother of King Richard, Prince John, Joan and Eleanor of Castile. The illegitimate son of Henry II and the crown’s most dependable enforcer. Unlike his volatile half-brother Geoffrey, William is a pragmatic soldier-statesman who owes his fortune and title entirely to Richard’s favor. He serves as the iron hand of the regency, holding the strategic Earldom of Salisbury as a bulwark against the internal chaos of 1191. His oath to the "Lionheart" remains his north star. He is a survivor who understands that a bastard's power depends on a stable throne, making him the rare Plantagenet who values a sworn oath as much as a sharp blade.
