Some historical background on the Swiss military from The Swiss Army System by Remy Feesch
"Some facts of Swiss history may explain how the military spirit has developed and has always been kept up in that little Republic, and that the actual state of preparedness is partly the result of that military spirit of the Swiss population.
The foundation of Switzerland dates from the 1st of August 1291, when those farmers and huntsmen round the Lake of Lucerne assembled on the 'Rütli' and after deliberation took a solemn oath to defend one another and to destroy those tyrants which Austria had sent to subdue the country.
Already in those days general conscription formed a basis and was a principle of the swiss military system. It was a matter of course to the Swiss people that every able bodied man or boy should defend his country.
For the next few hundred years we find the Swiss continuously fighting for independence against almost every power in Europe. The Swiss Regiments became quite famous and when there was nothing to fight for at home, they sold their sword abroad. We find Swiss Regiments fighting with the armies of Philipp II, Francis I, and Charles V. During the terrible struggle of the French Revolution in 1792 the famous 'Red Swiss,' a Regiment of body guards of Louis XVI, were entirely annihilated in the garden of the Tuilleries by the bloodthirsty mob of Paris."
