How did the Hundred Years’ War contribute to the decline of Anglo-Norman in England?

The Hundred Years’ War played a significant role in the decline of Anglo-Norman in England by fostering a sense of alienation toward France. As the long-standing military conflict intensified, it fueled a growing national consciousness in England, which in turn encouraged an increasing use of the English language in public and official spheres.12

Before this shift, Anglo-Norman had served as the prestigious vernacular of the court, law, church, and government following the Norman Conquest. However, the protracted struggle against the French made the continued dominance of a French dialect less tenable. By the late 14th century, English began to be used in Parliament alongside French, and it increasingly appeared in public documents and records. While Anglo-Norman persisted as a specialized language in certain legal and parliamentary formulas, the war effectively accelerated the transition toward English as the primary medium for literature and administration.12
