Understanding Europe, by Christopher Dawson

This is an outstanding analysis of Europe and Western civilization.  The book is divided in two parts.

In the first part, Dawson describes what Europe is: a society of peoples whose culture was shaped both by Christianity and the Greco-Roman heritage.  Through comparisons, he explains what differentiates it from Asia, describes the special case of Russia, and discusses the regional differences among the different peoples.  These were produced by the splintering of Christianity during the Reformation and the different styles of government in the different regions, contrasting the parliamentary governments that sprung up in Western Europe with the large military empires that developed in Central and Eastern Europe.  He also devotes two chapters to Europe's overseas colonies: the dual nature of European colonialism and how each nation's colonial effort differed in character from one another.

The second part of the book is about the decline of Western culture and the revolt, starting in the eighteenth century, against the ideas and norms that used to unify Europe.  He describes the rise of the large totalitarian and authoritarian states, how the ideas behind this style of government originated in Hegelian philosophy, and how the two world wars came about.

For a relatively short (230 page) book, he covers a lot of ground, and it's definitely a book that you have to read more than once in order to properly digest the material.  It's best to have a reasonably good general knowledge of the history of the various European countries in order to appreciate this book properly.
