As early as 400 BC the foothills of the Alps were already heavily populated and the Styrian population was already settled: first as farmers, then later, in the Bronze Age, came mining, trading and crafts.
The first characteristics of a new cultural community emerged later during the transition to the Hallstatt period. Even then, the Styrians showed themselves to be an independent people. They founded their own Hallstatt group within the Eastern Hallstatt area.
The Celts arrived and celtified the area entirely in 300 BC.
The pre-historic settlement of Styria took place over a wide area: the Dachstein, Totes Gebirge (The Dead Mountains), the Ennstal Alps, Warscheneck, the Hochschwab, the Zeller Staritzen, Veitsch, Schneealpe, Tonion, Kräuterin, Grebenzen, Hochlantsch, Tanneben bei Peggau and Schöckl. In all of these area there are large and small caves. As many special finds prove, some of these served as shelters for pre-historic man.
