Neustria

Neustria (/ˈnuːstriə, ˈnjuː-/) or Neustrasia (meaning "new [western] land" in contrast to Austrasia) was the western part of the kingdom of the Franks that was created in 511 upon the division of the Merovingian kingdom of Clovis I to his four sons following his death.

Neustria was made up of the regions between Aquitaine and the English Channel, approximately the north of present-day France, with Paris and Soissons as its main cities. It later referred to the region between the Seine and the Loire rivers known as the regnum Neustriae, a constituent subkingdom of the Carolingian Empire and then West Francia. The Carolingian kings also created a March of Neustria which was a frontier duchy against the Bretons and Vikings that lasted until the Capetian monarchy in the late 10th century, when the term was eclipsed as a European political or geographical term.

Neustria was also employed as a term for northwestern Italy during the period of Lombard domination. It was contrasted with the northeast, which was called Austrasia, the same term as given to eastern Francia. For this meaning of the term, see Neustria (Italy).
