The poetry and music of the trouvères in Northern France is the focus of Chapter 5. We explore the lives and music of Chrétien de Troyes, Adam de la Halle, Gautier de Coinci, Rutebeuf, and the female trouvère Gertrude of Dagsburg. We chart the ways in which the trouvères modelled themselves on the Occitan troubadours, translating their concept of courtly love, along with their song forms and genres, into an Old French linguistic context. We also consider some of the key differences between the two spheres, especially the increasingly urban - rather than courtly - environment in which the thirteenth-century trouvères worked, and their greater involvement in literary and musical production beyond songs, such as romances (romans) and other narrative poetry, and the French motet. The emergence of distinctive poetic-musical structures, known as the formes fixes, was another key feature of thirteenth-century French song, as was the phenomenon of refrains, or snippets of song, that were borrowed and quoted across a wide range of musical and literary genres.

The entry of the United States doomed the Central Powers in the long run but not during 1917, as the collapse of Russia deprived the Allies of their largest army at a time when the Americans could not yet make good the loss. Unable to afford a repeat of the bloody battles of 1916, the Germans resolved to stand on the defensive in the west while the U-boats (and the Bolsheviks) did their work. Meanwhile, the failure of Nivelle’s spring offensive nearly broke the French army, leaving it paralyzed by mutiny for much of the rest of the year, while British and Imperial troops attacked at Arras and Vimy Ridge in the spring, then at Passchendaele in the summer and autumn, gaining little ground at great cost. A November attack at Cambrai, ultimately indecisive, showed how tanks could be used effectively. On other fronts, Russia’s attempt to use Czech deserters against Austria-Hungary was more successful than Germany’s efforts to use Polish deserters against Russia, but not decisively so. The Allies added Greece to their ranks by overthrowing its pro-German king, but nearly lost Italy after the Central Powers achieved a decisive victory at Caporetto, and lost Romania when Russia sued for peace.
