-----------
William IX (
French: Guillaume de Poitiers ;
Occitan: Guilhèm de Peitieus) (22 October 1071 – 10 February 1126), called
the Troubador, was the
Duke of Aquitaine and
Gascony and
Count of Poitou (as
William VII) between 1086 and his death. He was also one of the leaders of the
Crusade of 1101. Though his political and military achievements have certain historical importance, he's best known as the earliest
troubadour[1] — a vernacular lyric poet in the
Occitan language — whose work survived.
William was the son of
William VIII of Aquitaine by his third wife,
Hildegarde of Burgundy. His birth was a cause of great celebration at the Aquitanian court, but the Church at first considered him illegitimate because of his father's earlier divorces and his parents'
consanguinity. This obliged his father to make a pilgrimage to
Rome soon after his birth to seek
Papal approval of his third marriage and the young William's legitimacy.
