Switzerland is also rated more free than us now...and, they have not had a war since 1551. An excellent country to immigrate to if you can satisfy their immigration criteria...although you can live there for extended time without problem.
Switzerland had a civil war in 1847.
Sorry, that's wrong
1653: The Swiss Peasant's war: Lucerne, Berna, Basel etc. who were agricultural revolted against the urban cantons of Zurich etc. Bern and Lucerne were beseiged
1798: Switzerland was conquered by the French and converted into the "Helvetic Republic" which was really a French proxy. And it remained as such until 1815 and the Congress of Vienna
Then in 1847 there was the Swiss Civil war -- the Sonderbundskreig which started after seven Catholic cantons formed the Sonderbund ("separate alliance") in 1845 to protect their interests against a centralization of power. The Catholic cantons wanted a federal state, the Calvinist counties wanted a strong central government and started to shut down monasteries etc.
THIS, 1847 is what made Switzerland that island of neutrality. Earlier it was a consquence of location, but post this, it was national imperative.
