Noricum was incorporated into the Roman Empire in 16 B.C.

Noricum in ancient geography was a Celtic kingdom stretching over the area of today's Austria and Slovenia, and later a province of the Roman Empire. It was bounded on the north by the Danube, on the west by Raetia and Vindelicia, on the east by Pannonia, on the south by Pannonia, Italia and Dalmatia. It roughly corresponds to the greater part of modern Styria and Carinthia, and part of Austria west of Vienna, Bavaria and Salzburg.
