How did Latin and French limit the use of Dutch in early medieval writing?

In the early Middle Ages, the use of Dutch in written form was significantly limited because Latin and, subsequently, French served as the primary languages of the educated and the elite.1

During this period, Latin functioned as the dominant language for administration, theology, philosophy, and literature across Europe. Because these languages held such high status, the vernacular Dutch was largely relegated to unrecorded oral traditions, such as folk songs and legends. Consequently, very little written material in the vernacular survives from the Low Countries prior to 1200, with the exception of limited records like the 10th-century "Wachtendonck Psalm Fragments". It was not until the Middle Dutch period, beginning around 1200, that a substantial corpus of literary and nonliterary documents in the vernacular began to emerge.213
