The oldest settlement on the ground of the modern city of Graz dates back to the Copper Age. However, no historical continuity exists of a settlement before the Middle Ages. The city was originally called "Bayrischgraz" or "Bavarian Graz" (i.e. German Graz) by the German founders to distinguish it from the elder "Windischgraz" or "Slovenian Graz". Bavarian Graz however soon eclipsed its Slovenian counterpart and henceforth Graz always referred to the German one.
