Book excerpt: Bismarck’s role in the unification and consolidation of Germany is central to any understanding of Germany's development as a nation and its consequent role as aggressor in two world wars. This study provides students with a concise, up-to-date and analytical account of Bismarck's role in modern German history. Williamson guides readers through the complex events leading to the defeats of Austria and France in 1866 and 1870 and the subsequent creation of a united Germany in January 1871. He then explores the domestic and foreign problems Bismarck faced up to 1890 in consolidating unification.
