Drei Bünde
"Raetia" as a geographic designation remained in use at the end of the medieval period, when political power passed to the Three Leagues ("Drei Bünde") federation. When the Free State of the Three Leagues eventually joined the Helvetic Republic in 1798, the territory was incorporated as the Canton of Raetia. Finally, with the Napoleonic Act of Mediation of 1803, establishing the Swiss Confederacy, the canton was named Grisons ("Graubünden").
