Around 800 BC, the region was inhabited mostly by the people of the local Celtic Hallstatt culture. Around 450 BC, they merged with the people of the other core Celtic areas in the south-western regions of Germany and eastern France. The country is mountainous and rich in iron and salt. It 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. Gold and salt were found in considerable quantities. The plant called saliunca grew in abundance and was used as a perfume according to Pliny the Elder. The Celtic inhabitants developed a culture rich in art, cattle breeding, salt mining and agriculture. When part of the area became a Roman province, the Romans introduced water management and the already vivid trade relations between the people north and south of the alps boosted - Noric steel was famous for its quality and hardness. Archaeological research, particularly in the cemeteries of Hallstatt, has shown that a vigorous Celtic civilization was in the area centuries before recorded history, but the Celtic Hallstatt civilization was a cultural manifestation prior to the other Celtic invasions, The Hallstatt graves contained weapons and ornaments from the Bronze Age, through the period of transition, up to the "Hallstatt culture", i.e., the fully developed older period of the Iron Age.
Language
The Noric language is attested in only fragmentary inscriptions, one from Ptuj and two from Grafenstein, neither of which provide enough information for any conclusions about the nature of the language.
Steel for Roman weaponry
The kingdom of Noricum was a major provider of weaponry for the Roman armies from the mid-Republic onwards. Roman swords were made of the best-quality steel then available from this region, the chalybs Noricus. The strength of steel is determined by its composition and heat treatment. The wrought iron produced in the Greco-Roman world was too soft for tools and weapons. Ore from Noricum, by contrast, could yield a superior product. The ore needed to be rich in manganese, and contain little or no phosphorus, which weakens steel. The ore mined in Carinthia fulfilled both criteria particularly well. The Celts of Noricum discovered their ore made superior steel around 500 BC and built a major steel industry. At Magdalensberg, a major production and trading centre, specialised blacksmiths crafted metal products and weapons. The finished arms were exported to Aquileia, a Roman colony founded in 180 BC. From 200 BC the Noricum tribes gradually united into a kingdom, known as the regnum Noricum, with its capital at a place called Noreia. Noricum became a key ally of the Roman Republic, providing high-quality weapons and tools in exchange for military protection. This was demonstrated in 113 BC, when Teutones invaded Noricum. In response, the Roman consul Gnaeus Papirius Carbo led an army over the Alps to attack the Germanic tribes at the Noreia.
Roman rule
Noricum was incorporated into the Roman Empire in 16 BC. For a long time previously, the Noricans had enjoyed independence under princes of their own and carried on commerce with the Romans. In 48 BC they took the side of Julius Caesar in the civil war against Pompey. In 16 BC, having joined with the Pannonians in invading Histria, they were defeated by Publius Silius Nerva, proconsul of Illyricum. Thereafter, Noricum was called a province, although it was not organized as such and remained a kingdom with the title of regnum Noricum, yet under the control of an imperial procurator. Under the reign of Emperor Claudius the Noricum Kingdom was ultimately incorporated into the Roman Empire apparently without offering resistance. It was not until the reign of Antoninus Pius that the Second Legion, Pia was stationed in Noricum, and the commander of the legion became the governor of the province. Under Diocletian, Noricum was divided into Noricum ripense, and Noricum mediterraneum. The dividing line ran along the central part of the eastern Alps. Each division was under a praeses, and both belonged to the diocese of Illyricum in the Praetorian prefecture of Italy. It was in this time that a Christian serving as a military officer in the province suffered martyrdom for the sake of his faith, later canonised as Saint Florian. The Roman colonies and chief towns were Virunum, Teurnia, Flavia Solva, Celeia in today's Slovenia, Juvavum, Ovilava, Lauriacum. Knowledge of Roman Noricum has been decisively expanded by the work of Richard Knabl, an Austrian epigrapher of the 19th century. The transition from Roman to barbarian rule in Noricum is well documented in Eugippius' Life of Saint Severinus, providing material for analogies for this process in other regions where primary sources from the period are lacking.
In modern politics
In 1919, Heinrich Lammasch, the last prime minister of Imperial Austria, proposed to give the young republic the name of Norische Republik or Noric Republic, because the ancient borders were similar to those of the new state, which – at the time – did not wish to be considered the heir of the Habsburg monarchy, but an independent, neutral and peaceful state.
