The Battle of Mortemer took place in 1060 in Normandy, France, where the forces of Duke William of Normandy faced off against the rebellious Norman barons. This conflict was pivotal in consolidating William's power, which would later facilitate his conquest of England in 1066. The battle exemplified the feudal struggles of the time and highlighted the shifting allegiances that characterized the Norman nobility.

The events surrounding the Battle of Mortemer and the subsequent Norman Conquest inspired many medieval poets and chroniclers, including Wace, who wrote 'Roman de Brut,' capturing the essence of the era's conflicts and heroism. The themes of loyalty and valor in these narratives influenced later literary traditions, including the chivalric romances of the 12th century.
