Oaths of Strasbourg

At Strasbourg Louis the German and Charles the Bald sealed their alliance against their elder brother Lothair with oaths sworn in the vernacular, so that each other’s armies could understand them. Recorded by the historian Nithard, the Romance oath is regarded as the oldest surviving text in an early form of French, and the German one as an early monument of Old High German.

After Louis the Pious died in 840, his eldest son Lothair claimed authority over the whole empire. His younger brothers Louis the German and Charles the Bald defeated him at Fontenoy on 25 June 841, and on 14 February 842 they met with their armies at Strasbourg. According to Nithard, the two kings first addressed the assembled troops, one in German and the other in Romance, explaining why they had joined forces against Lothair. Then Louis, as the elder, swore first, in the lingua romana, so that Charles’s men could understand him, and Charles repeated the oath in the lingua teudisca for Louis’s men. Finally each army swore in its own language that if its king broke his word, it would give him no help against his brother.

Nithard, a grandson of Charlemagne through his daughter Bertha and a partisan of Charles, copied the oaths into his Latin history of the quarrels of the sons of Louis the Pious, written in the early 840s; the text survives in a manuscript of about the year 1000 in the Bibliothèque nationale de France. Some scholars think the Romance oath was translated from a lost Latin draft, and its dialect is disputed — it has been placed in regions from Picardy and Lorraine to Poitou and Lyon. The philologist Philippe Walter sees in the Romance oath the written debut of the vernacular. A year and a half later the three brothers agreed on the partition of the empire at Verdun.
