Noricum is the Latin name for a Celtic kingdom, or federation of tribes, that included most of modern Austria and part of Slovenia. In the first century AD, it became a province of the Roman Empire. Its borders were the Danube to the north, Raetia and Vindelicia to the west, Pannonia to the east and southeast, and Italia (Venetia et Histria) to the south. The kingdom was founded around 400 BC, and had its capital at the royal residence at Virunum on the Magdalensberg.
Its area corresponded to the greater part of modern Styria and Carinthia, Upper/Lower Austria west of Vienna, Salzburg, a part of Bavaria, and a part of Slovenia. The original population appears to have consisted of Illyrians, who after the great migration of the Gauls, became subordinate to various Celto-Ligurians tribes, chief amongst them being the Norici (so called after their capital Noreia), who were possibly identical with the Taurisci of Roman sources.
The country is mountainous and the soil relatively poor except in the southeastern parts, but it proved rich in iron and supplied material for the manufacturing of arms in Pannonia, Moesia, and northern Italy. The famous Noric steel was largely used in the making of Roman weapons (e.g. Horace, Odes, i.16.9-10: Noricus ensis, "a Noric sword"). Gold and salt were found in considerable quantities. The plant called saliunca (the wild or Celtic nard, a relative of the lavender) grew in abundance and was used as a perfume according to Pliny the Elder.
