The whole population of the northern part of today’s Switzerland was on the move in 58 BC. The Rauraci, Helvetii and some other Celtic tribes moved to France, the territory inhabited by other Celtic tribes. They were beaten by the army of Julius Caesar in 58 in the battle of Bibracte, close to Autun, and forced back to their Swiss territories. The Swiss Roman museums in Vallon and Avenches organize an exhibition dedicated to immigration and integration in the Roman Empire. The exposition deals with all relevant aspects, such as religion, work, language and culture. Why and to what extent is the present situation different is not the main question of this show, but the Roman Empire had unifying factors, which are lacking today.
