Blondel de Nesle – either Jean I of Nesle (c. 1155 – 1202) or his son Jean II of Nesle (died 1241) – was a French trouvère. The name 'Blondel de Nesle' is attached to twenty-four or twenty-five courtly songs. He was identified in 1942, by Holger Dyggve, as Jean II of Nesle (near Amiens), who was nicknamed 'Blondel' for his long blond hair. He married at the time of his father's death in 1202, and that same year, went on the Fourth Crusade; he later fought in the Albigensian Crusade. However, in 1994, Yvan Lepage suggested that the poet may have been Jean I, father of Jean II, who was Lord of Nesle from 1180 to 1202; this Jean took part in the Third Crusade, which may explain the subsequent legend linking him with King Richard I of England.
