During the reign of the Emperor Augustus (27 BC - 14 AD) Roman power expanded to the East Central Europe and moved the Empire border all way to the Danube. On the occupied territory between the eastern Alps and the Danube, inhabited mostly by Celtic and Pannonian tribes a new province - Pannonia - was declared. The flow of Danube become then a northern and eastern border of the province, as well as of this part of the Empire, for next four centuries.

At the same time the Germanic tribes of Suebi started to penetrate the territories north of the Danube. On the territory of today southern Moravia (the Czech Republic) and Lower Austria settled Marcomanni and the south-west Slovakia was occupied by Quadi. The relationship of Romans and Germanic tribes started to develop in the 1^st century AD very positively. Germanic kings such as Vannius of a Quadi tribe and also his successors Vangio, Sido and Italicus became the vassals of Rome, on the other hand they were able to profit from a very good geographic situation of their seats. They profit from the gifts of friendship and supporting the peace, but mostly from the exchange on the border and trade on the long-distance Amber route connecting the north Adriatic and Baltic seas. Several of its branches crossed the Marcomanni  and Quadi territory. Prominent population growth and the strengthening of the power of Germanic tribes on the Danube led to an attempt to liberate from the vassal dependence to Rome already in the end of the 1^st century AD.
