Septimania

Septimania is a historical region in modern-day Southern France. It referred to the western part of the Roman province of Gallia Narbonensis that passed to the control of the Visigoths in 462, when Septimania was ceded to their king, Theodoric II. The region was also variously known as Gallia, Arbuna or Narbonensis. Septimania territory roughly corresponds with the modern French former administrative region of Languedoc-Roussillon that merged into the new administrative region of Occitanie. Septimania was conquered by the Muslims in the 8th century, when it was known as Arbuna and was made part of Al-Andalus. It passed briefly to the Emirate of Córdoba, which had been expanding from the south during the eighth century, before its subsequent conquest by the Franks, who by the end of the ninth century termed it Gothia or the Gothic March .
