Austrasia was a territory which formed the north-eastern section of the Merovingian Kingdom of the Franks during the 6th to 8th centuries. It was centred on the Meuse, Middle Rhine and the Moselle rivers, and was the original territory of the Franks, including both the so-called Salians and Rhineland Franks, which Clovis I conquered after first taking control of the bordering part of Roman Gaul, now northern France, which is sometimes described in this period as Neustria.
