ancient history of switzerland
In 15 BC, the Romans conquered the Alps and the region became part of the Roman Empire. The Helvetii region, at this time inhabited by an ancient Celtic civilization, became part of Gallia Belgica and was later included in the province of Germania Superior. The Eastern part was integrated into the Roman Province of Raetia.
In the early Middle Ages, the Swiss Plateau and valleys of the Alps were settled by the Alemanni, before being incorporated in the Frankish Empire and divided between Alemannia and Upper Burgandy.
By AD 1200 the Swiss Plateau was divided between the dominions of the houses of Savoy, Zahringer, Habsburg and Kybulg.
