Chiavenna
Chiavenna was an Alpine town and county on the approaches to the Splügen and Septimer passes. The Visconti of Milan acquired the town in 1335.
The Three Leagues conquered Chiavenna in the early sixteenth century and ruled it as a subject territory. A Protestant parish appeared in 1542, and Italian religious refugees settled there. In 1797 the French incorporated Chiavenna into the Cisalpine Republic.
