Reviewing in English for consistency with my stream.
This is a short but unfortunately rather dry history, and the German level is a little high for the average non-native student. It is small enough to be read in a couple of evenings, and details some important events and pseudo-events, such as the Tell legend and the Sempacherbrief. It has less to say about the philosophical and ideological foundations of the Swiss Eidgenossenschaft.
The confessional rivalries of the wars of the Reformation are addressed, as is the difficult relationship with Switzerland's fascist neighbours and Holocaust survivors during and after the German Nazi period. I was surprised to find just how late conflicts persisted between rival Swiss states and cities - into the 19th Century, in fact.
Also interesting to note is that Swiss mercenaries, well respected at the time for the good reason that Swiss mountain people are as tough as granite, fought on both sides in wars such as that for the Spanish succession. As a result, the Swiss bled manhood fighting each other for the benefit of foreign powers who saw their interests furthered at next to no human cost, in conflicts at best tangential to Swiss concerns. Something had to be done, and this is a factor in Swiss neutrality, although this history does not really draw attention to it.
A section is devoted to post-War times and the European Union, although again it is not really highlighted to what extent direct democracy conflicts fundamentally with a political union.
All in all this is a solid little history, but a bit hard to read and with some lacunae, from my perspective.
