Earlier this year, I read the following books in the order shown and despite the order being historically backwards, the three together (and, indeed, individually) gave an eerie picture of the world today. The circumstances of the times may be different, but what is happening today is very similar.
The books were:
Travellers in the Third Reich, Julia Boyd, which looks at the rise of Facism in Germany from 1929-1934 through the eyes of visitors to Germany, politicians, businessmen, tourists, students, sports men and women;
The War that Ended Peace, Margaret Macmillan, which looks at Europe from 1900 to 1914, year by year and the relations between the major European countries;
The Age of Decadence, Britain 1880 - 1914, Simon Heffer, which looks at the social changes and stresses in Britian over those years.
Apart from the first, all are long reads (MacMillan is 605 pages of main text and Heffer 826), but all are interesting and eye opening. MacMillan, for example, argues that Europe drifted into war because the major countries believed war couldn't happen after nearly 45 years of peace following the 1870-1871 war between France and Prussia - yes in that time there had been tensions and close calls which came close to a war between two or more European powers, but something always turned up in the end to prevent it. After something like 75 years without major war, has the world drifted into a similar mindset?
Heffer puts forward the view that Britain from its peak of economic and naval power and as the major global power, withdraws from the rest of Europe, regarding itself as unaffected by what may happen there, but in doing so increasingly is living in a world of nostalgia for a Victorian high peak which is passed, with Germany and the USA overtaking her both economically and globally in particular, and with her not realising that she is not and cannot be isolated from what happens in Europe.
Boyd in large measure leaves the reader to react,. She documents what people wrote or said about Germany as politics moved increasingly towards violence against minority groups and towards the extreme right, not in a great rush but in a slow, drip by drip process, with vilification of Jews and some foreigners such as Roma becoming for many in Germany and visiting Germany, and the resulting rise of Nazism as being just something that was happening.
This may all sound boring, but it isn't.
EDIT: MacMillan and Heffer are on oppsite sides of the political spectrum, MacMillan being liberal and Heffer conservative.
