German Unification
Prussia unified Germany not through parliamentary debate but through three calculated wars, engineered by Otto von Bismarck, that made Prussian military and economic strength the magnet for the other German states.
Germany in 1850 was a patchwork of states loosely tied together in the German Confederation, with Austria and Prussia competing for leadership. Austria looked grander, heir to the Holy Roman Empire, but it was multiethnic and militarily creaky, stretched thin holding together Hungarians, Czechs, and Italians. Prussia was smaller but industrializing fast, with the Zollverein trade union already binding other German states to its economy. Otto von Bismarck, appointed minister-president in 1862, bet that blood and iron, not speeches and majority votes, would decide Germany's future.
He built the empire through three wars, each isolating an opponent before striking. In 1864 Prussia and Austria together beat Denmark over Schleswig-Holstein. In 1866 Bismarck turned on Austria itself: Prussia's railways rushed troops to the front faster than Austria could respond, its needle guns let infantry reload lying down while Austrian soldiers stood to reload muzzle-loaders, and a professional general staff coordinated the whole campaign. Austria fell in seven weeks, and was excluded from Germany for good. In 1870 Bismarck provoked France by editing the Ems Telegram to sound insulting to both the Prussian king and the French ambassador, then leaked it. France declared war, lost fast, and the southern German states joined Prussia in patriotic reaction. In January 1871 the German Empire was proclaimed at Versailles.
The new empire's constitution gave it a Reichstag elected by universal male suffrage, but real power sat with the Prussian king, now Kaiser, and his chancellor, answerable only to the throne. This lopsided balance of 1815 fell apart: a massive, industrial, militarized state now sat in the center of Europe, and every power had to recalculate around it.
