Rhætia

Rhætia, an ancient Roman province embracing a large part of the Alpine tract between the basins of the Po and the Danube, now included in the Grisons and the Austrian Tyrol. Its inhabitants were brave and turbulent, and were only subdued by Drusus and Tiberius after a desperate resistance. The province was then formed, to which Vindelicia was soon added; but later Rhætia was subdivided into Rhætia Prima and Rhætia Secunda (Vindelicia). The only important town in Rhætia was Tridentinum (Trent); the colony of Augusta Vindelicorum (Augsburg) was in its northern part.—For Rhætic Beds, see TRIASSIC SYSTEM.
