For given time periods, did Switzerland literally experience "X uninterrupted years of democracy and peace"?

Some examples of Swiss brotherly love over the past 500 years:

• 1845 Armed radicals [radicalized liberals] march for Lucerne, they are defeated by regular troops.

• 1847-1848 The Sonderbund War a civil war.

I'm aware I'm missing some references (will probably fix later). Also I'm occasionally pointing to Wikipedia, but only as a matter of "things have been written about this event" and not for the actual content so much, I might also fix that later.

Notable historical Swiss figures 1450-1950

• Leonard Euler (1707-1783), one of the most famous and most productive mathematicians of all time.

Leonhard Euler was by far the most productive mathematician in the history of humankind and one of the greatest scholars of all time. He was cosmopolitan in the truest sense of the word: he spent his first 20 years in Basel, and worked altogether more than 30 years in St. Petersburg and a quarter century in Berlin. As happens to only a very few scholars, Euler's work brought him fame and popularity, comparable to that of Galileo, Newton, and Einstein.

Answering this is such a huge undertaking I've decided to make the answer a community wiki if anyone wants to chip in with better references and to make a more complete answer.
