Historiographical synthesis & structured realm registry
The County of Flanders was one of the most powerful political entities in the medieval Low Countries, located on the North Sea coast of modern-day Belgium and north-eastern France. Unlike the neighbouring states of Brabant and Hainaut, it was within the territory of the Kingdom of France. The counts of Flanders held the northernmost part of the kingdom, and were among the original twelve peers of France. For centuries, the economic activity of the Flemish cities, such as Ghent, Bruges, Ypres and Lille, made Flanders one of the most affluent regions in Europe, and also gave them strong international connections to trading partners.

History
Julius Caesar conquered the areas South of the Rhine in Gaul around 54 BC and the population was partially romanised from the 1st to the 3rd century. When the Roman Empire started to decline in the fifth century, most of the Roman population retreated below a line formed by the Roman road that connected Cologne with Boulogne-sur-Mer through Bavay. In the south, the Gallo-Romanic population was able to maintain itself, while the north became a no-mans land that also suffered from regular floods from the North Sea. This void was filled by Germanic speaking Franks.
The first wave of immigration in the present day Flemish territory was accompanied by limited Christianisation. In the wake of the immigrants, missionaries tried to convert the heathen population, but had little success.
