Old Frisian

Old Frisian was a West Germanic language spoken between the late 13th century and the end of the 16th century. It was spoken by Frisians who comprised a loose confederacy along the North Sea coast from around modern-day Bruges in Belgium to the Weser River in modern-day northwestern Germany. The vast majority of the surviving literature is composed of legal documents and charters, though some poetry, historiographies, and religious documents are attested as well. An early standard language for the Frisians, surviving texts show remarkable uniformity across time and space.
