and administrative centers. Excavations of Lusatian hill forts document the substantial development of trade and agriculture at that period. The richness and the diversity of tombs increased considerably. The inhabitants of the area manufactured arms, shields, jewelry, dishes, and statues.
The arrival of tribes from Thrace disrupted the people of the Calenderberg culture, who lived in the hamlets located on the plain (Sereď), and also in the hill forts located on the summits (Smolenice, Molpí). The local power of the "Princes" of the Hallstatt culture disappeared in Slovakia during the last period of the Iron Age after strife between the Scytho-Thracian people and the Celtic tribes, who advanced from the south towards the north, following the Slovak rivers.
From around 500 BC, the territory of modern-day Slovakia was settled by Celts, who built powerful oppida on the sites of modern-day Bratislava and Havránok. Biatecs, silver coins with the names of Celtic Kings, represent the first known use of writing in Slovakia. From 2 AD, the expanding Roman Empire established and maintained a series of outposts around and just north of the Danube, the largest of which were known as Carnuntum (whose remains are on the main road halfway between Vienna and Bratislava) and Brigetio (present-day Szöny at the Slovak-Hungarian border).
Near the northernmost line of the Roman hinterlands, the Limes Romanus, there existed the winter camp of Laugaricio (modern-day Trenčín) where the Auxiliary of Legion II fought and prevailed in a decisive battle over the Germanic Quadi tribe in 179 AD during the Marcomannic Wars. The Kingdom of Vannius, a kingdom founded by the Germanic Suebian tribes of Quadi and Marcomanni, as well as several small Germanic and Celtic tribes, including the Osi and Cotini, existed in Western and Central Slovakia from 8–6 BC to 179 AD.
