William Marshal, 1st Earl of Pembroke (1147 – 14 May 1219), also called William the Marshal.
Shot of 'Willow William' at Cilgerran Castle, who took the castle in 1204 from Gruffudd ap Rhys, son of the Lord Rhys.
He served five English kings—Henry II, his sons the "Young King" Henry, Richard I, John, and John's son Henry III.
Knighted in 1166, he spent his younger years as a knight errant and a successful tournament competitor; Stephen Langton eulogised him as the "best knight that ever lived."
In 1189, he became the de facto Earl of Pembroke through his marriage to Isabel de Clare, though the title of Earl would not be officially granted until 1199 during the second creation of the Pembroke Earldom.
In 1216, he was appointed protector for the nine-year-old Henry III, and regent of the kingdom.
Before him, his father's family held a hereditary title of Marshal to the king, which by his father's time had become recognised as a chief or master Marshalcy, involving management over other Marshals and functionaries. William became known as "the Marshal", although by his time much of the function was delegated to more specialised representatives (as happened with other functions in the King's household).
Because he was an Earl, and also known as the Marshal, the term "Earl Marshal" was commonly used and this later became an established hereditary title in the English Peerage.[
