Austrasia was a historical region in the early Middle Ages, primarily located in what is now northeastern France, Luxembourg, and parts of Belgium and Germany. It emerged as a significant part of the Frankish Kingdom during the Merovingian dynasty, serving as a center of power and culture. The region was known for its strong agricultural economy and played a crucial role in the political landscape of the time. Austrasia often competed with Neustria, another Frankish kingdom, leading to various power struggles and conflicts that shaped the future of the Frankish Empire.
