Switzerland is a country with four main languages. 75 years ago, Romansh was recognized as the fourth national language by ballot. Since then, it has been declared a dead language many times over. If you visit the Engadin Valley in Grisons, it will show that the language is alive and kicking. It is alive thanks to the children of migrant workers living there.
According to Swiss history writing, the foundations for modern Switzerland date to 1291. The date being conveniently close to the dissolution of the Order of the Knights Templar many see a connection between the two in later developments. Did the Knights Templar bring their legendary treasure to Switzerland and made it as rich as it is?
