The Agri Decumates or Decumates Agri were a region of the Roman Empire's provinces of Germania superior ("Upper Germania") and Raetia; covering the Black Forest, Swabian Jura, and Franconian Jura areas between the Rhine, Main, and Danube rivers; in present southwestern Germany, including present Frankfurt, Stuttgart, Freiburg im Breisgau, and Weißenburg in Bayern.
During the last phase of the campaigns in the spring of 15 BC two Roman armies under Drusus and Tiberius set out to subdue Raetia.
In 15 BC, Augustus' stepsons Drusus and Tiberius (later Emperor Tiberius Claudius Nero 14 to 37 AD) integrated the territory on the left side of Lake Zurich into the Roman provinces Raetia and Germania Superior.
The first home game was on May 26, 2012 against the fifth Team of FC St. Pauli in Domat/Ems and Raetia won 6 to 0.
This Pre-Roman dialect (the Swiss Rhaetian or Raetia) is one of four official languages of Switzerland by the Swiss German, Swiss Italian and Swiss French.
