Modelled on the Old French chanson de geste, it was composed in two distinct parts: William of Tudela wrote the first towards 1213, and an anonymous continuator finished the account.
[2] It is one of three major contemporary narratives of the Albigensian Crusade, the Historia Albigensis of Pierre des Vaux-de-Cernay and the Chronica of William of Puylaurens being the others.
This second part covers events from 1213 onwards and takes the opposite point of view, critical of the Crusaders and strongly in favour of the southerners (though not of Catharism).
The first critical edition was published with a French translation, as Chanson de la croisade contre les albigeois, by Paul Meyer in two volumes (1875–1879).
Eugène Martin-Chabot published another multi-volume edition and French translation under the title Chanson de la croisade albigeoise (1931–1961).
