Septimania was a region in the south of what is now France that was named after the Latin word for "seven cities." The timeline of Septimania starts in the 5th century when barbarians from the north invaded the Roman Empire and took control of the region.
During the 7th century, the region became part of the Visigothic Kingdom, which was a group of people who spoke a language called Gothic and were mostly based in Spain. The name "Septimania" was given to the area because there were seven cities that made up the region, including the city of Narbonne.
In the 8th century, the region was taken over by the Franks, who were a group of people from what is now Germany. They merged the region with their own kingdom and it became known as the Carolingian Empire. This empire included many different regions of Europe, including what is now France, Germany, and Italy.
Over the following centuries, Septimania was fought over by different groups of people, including the Moors, who were Muslims from North Africa. Eventually, the region became part of the Kingdom of Aragon, which was a region in Spain.
Today, the region is known as Languedoc-Roussillon and is a popular tourist destination known for its beautiful beaches and historic cities. The legacy of Septimania can still be seen in the area's historic architecture and culture.
