1. Realpolitik: Bismarck adopted a pragmatic approach known as Realpolitik, focusing on practical politics and national interests rather than abstract principles. He skillfully combined diplomacy, alliances, and realpolitik to advance Prussia's interests and ultimately unify Germany.
2. Diplomatic Alliances: Bismarck formed strategic alliances with neighboring countries to isolate potential adversaries and create favorable conditions for unification. In 1864, he allied with Austria to defeat Denmark in the Second Schleswig War and gained control of the duchies of Schleswig and Holstein.
3. Austro-Prussian War: In 1866, Prussia and Austria went to war over control of the duchies of Schleswig and Holstein. Prussia, led by Bismarck and with military leadership from Helmuth von Moltke, decisively defeated Austria and its allies in the Seven Weeks' War. This victory cemented Prussia's dominance in Germany.
4. North German Confederation: Following the Austro-Prussian War, Bismarck established the North German Confederation in 1867. It consisted of 22 German states under Prussian leadership and excluded southern German states such as Bavaria, Württemberg, and Baden.
5. Franco-Prussian War: In 1870, tensions between France and Prussia escalated, leading to the Franco-Prussian War. Bismarck skillfully provoked France into declaring war, ensuring that southern German states would side with Prussia in the conflict. Prussian forces, again led by Moltke, achieved swift victories against the French.
6. Unification Proclamation: With the resounding victory in the Franco-Prussian War, the southern German states agreed to join the North German Confederation. On January 18, 1871, the German Empire was proclaimed in the Hall of Mirrors at the Palace of Versailles, and King Wilhelm I of Prussia became the German Emperor.
Throughout the process of unification, Bismarck employed skillful diplomacy, political maneuvering, and military alliances to overcome regional differences, rivalries, and external threats. His policies emphasized military strength, economic development, and a strong centralized government, which laid the foundation for the unified German Empire.
