[1] The study of the Crusade song, which may be considered a genre of its own, was pioneered by Kurt Lewent.
Since Lewent, scholars have added several classifications and definitions of Crusade songs.
The Third and Fourth Crusades generated many songs in Occitan, French, and German.
Occitan troubadours dealt especially with the Albigensian campaigns in the early thirteenth century, but their decline thereafter left the later Crusades—Fifth, Sixth, Seventh, and Eighth—to be covered primarily by the German Minnesänger and French trouvères.
