The Cottian Alps (; ; ) are a mountain range in the southwestern part of the Alps. They form the border between France (Hautes-Alpes and Savoie) and Italy (Piedmont). The Fréjus Road Tunnel and Fréjus Rail Tunnel between Modane and Susa are important transportation arteries between France (Lyon, Grenoble) and Italy (Turin). Etymology The name Cottian comes from Marcus Julius Cottius, a king of the tribes inhabiting that mountainous region in the 1st century BC. These tribes had previously opposed but later made peace with Julius Caesar. Cottius was succeeded by his son Gaius Julius Donnus II (reigned 3 BC-4 AD), and his grandson Marcus Julius Cottius II (reigned 5-63 AD), who was granted the title of king by the emperor Claudius. On his death, Nero annexed his kingdom as the province of Alpes Cottiae. History For a long part of the Middle Ages the Cottian Alps were divided
