Editing Caracalla (section)

=== Barbaric invasion of the 3rd century ===
In 212 A.D., along the Germanic-Rhaetian limes, the confederation of the Alemanni appeared for the first time, a group of peoples, grouped along the borders of the provinces of Upper Germany and Rezia. Later, the Alemanni broke through the limes and forced the emperor to rush along this strategic sector to stem their possible invasion the following year. He had the communication routes of the Noricum repaired, where he created a new route from the Danube towards Linz, and in Rezia and Pannonia, as evidenced by the found milestones.

Also in Caracalla other successes on the barbarian populations along the middle-lower course of the Danube such as Quadi, Free Dacians, Goths and Carpi in 214 AD should be attributed. and first part of 215 A.D.
