How did Charlemagne’s educational reforms encourage Old High German literature?

Charlemagne’s educational reforms did not directly aim to promote Old High German literature; rather, their primary objective was to improve Latin literacy among the clergy and administrators to ensure the effective functioning of the church and state.123

However, these reforms indirectly encouraged the development of Old High German literature in several ways:

• Language Awareness: By standardizing and reviving "pure" Classical Latin, the reforms made it increasingly obvious that the vernacular spoken by the populace was a distinct language, creating a clearer distinction between Latin and the Germanic dialects.4
• Religious Instruction: To fulfill the goal of reeducating the populace in Christian doctrine, it became necessary to translate and adapt religious texts into the vernacular. This led to the production of scattered religious texts in various Old High German dialects, such as Otfrid of Weissenberg’s Evangelienbuch, a rhymed Gospel book.56
• Infrastructure: The educational infrastructure established during the Carolingian Renaissance—including the proliferation of schools and scriptoria—provided the necessary environment and tools for recording texts in the vernacular.123
