Frankish language
The Frankish language, also "Old Frankish", was the language of the Franks. It is a West Germanic language and was spoken in Merovingian times, preceding the 7th century. Austrasia formed the northeastern portion of the Kingdom of the Merovingian Franks (Francia), comprising parts of the territory of present-day western Germany, eastern and northern France, Luxembourg, Belgium, and the Netherlands. The Franks first established themselves in the Netherlands and Flanders before they started to fight their way down south and east. The language had a significant impact on Old French. It evolved into Old Dutch in the north and it was replaced step by step by the langues d'oïl in the south.
