Francia, the Frankish Kingdom (481–843), was the largest post-Roman polity in Western Europe, established by Clovis I and later extended under the Merovingian and Carolingian dynasties. It included a variety of subkingdoms such as Austrasia and Neustria, and eventually divided into West Francia (the precursor to France) and East Francia (the ancestor of Germany).
Historians such as George Park Fisher emphasize its political fragmentation, while Edward A. Freeman highlights the importance of the Duchy of France. Lucien Edward Henry focuses on the monarchy's role in uniting the nation. This heritage, based on Clovis’s unification and Charlemagne’s empire, influenced the lasting identities of France and Germany, as seen in the Capetian and Ottonian lineages.
