Верхняя Германия
The Emperor Domitian of the Flavian dynasty faced attacks from the Chatti in Germania superior, with its capital at Mainz, a large group which had not been in the alliance of Arminius or Maroboduus. The Romans claimed victory by 84 CE, and Domitian also improved the frontier defenses of Roman "Germania", consolidating control of the "Agri Decumates", and converting "Germania Inferior" and "Germania Superior" into normal Roman provinces. In 89 CE the Chatti were allies of Lucius Antonius Saturninus in his failed revolt. Domitian, and his eventual successor Trajan, also faced increasing concerns about an alliance on the Danube of the Suevian Marcomanni and Quadi, with the neighbouring Sarmatian Iazyges; it was in this area that dramatic events unfolded over the next few generations. Trajan himself expanded the empire in this region, taking over Dacia. Between 162 and 163, the Chatti once again attacked the Roman provinces of Raetia (with its capital at Augsburg) and Germania Superior.
