During the Hundred Years' War an English identity began to develop in place of the previous division between the Norman lords and their Anglo-Saxon subjects. This was a consequence of sustained hostility to the increasingly nationalist French, whose kings and other leaders (notably the charismatic Joan of Arc) used a developing sense of French identity to help draw people to their cause. The Anglo-Normans became separate from their cousins who held lands mainly in France and mocked the former for their archaic and bastardised spoken French. English also became the language of the law courts during this period.
