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 tribes at the Noreia.
