The legionary camps on the Danube in Pannonia were the backbone of the defense of Rome and the Apennine Peninsula. The camp territories became part of the Roman Empire at the beginning of the first century, when Tiberias expanded the empire's borders to the Danube. The Danube as a river had a border role, but it was also a great navigable waterway for both military and trade purposes. From the first century on, they become important point of defens of the Roman borders, but also the center of social life. Karuntum, Vindobona, Brigetio and Aquinum become the starting points of Romanization in the Danube region in the province of Pannonia. Initially, wooden camps were created, which over time became permanent stones, but apart from the camps, civilian cities, auxiliary camps, training camps, amphitheatres were also created, all of which indicate the importance of the space adjacent to the camps. Along with the camps, rich civilian cities also emerge, which will become centers of life in Pannonia.
