To the north of Italy, the Fascist regime in the 1930s had designs on the largely Italian-populated region of Ticino and the Romansch-populated region of Graubünden in Switzerland (the Romansch are a people with a Latin-based language). In November 1938, Mussolini declared to the Grand Fascist Council: "We shall bring our border to the Gotthard Pass". The Fascist regime accused the Swiss government of oppressing the Romansch people in Graubünden. Mussolini argued that Romansch was an Italian dialect and thus Graubünden should be incorporated into Italy. Ticino was also claimed because the region had belonged to the Duchy of Milan from the mid-fourteenth century until 1515, as well as being inhabited by Italian speakers of Italian ethnicity. Claim was also raised on the basis that areas now part of Graubünden in the Mesolcina valley and Hinterrhein were held by the Milanese Trivulzio family, who ruled from the Mesocco Castle in the late 15th century. Also during the summer of 1940, Galeazzo Ciano met with Hitler and Ribbentrop and proposed to them the dissection of Switzerland along the central chain of the Western Alps, which would have left Italy also with the canton of Valais in addition to the claims raised earlier.
