The Austro-Prussian War, also known as the Seven Weeks' War, was fought in 1866 between the Austrian Empire and the Kingdom of Prussia, with both sides aided by various allies within the German Confederation. The war was sparked by a dispute over the administration of Schleswig-Holstein, which both Prussia and Austria had conquered from Denmark and agreed to jointly occupy. Prussia, led by Chancellor Otto von Bismarck, had been challenging Austria's supremacy in the German Confederation and sought to establish a Kleindeutschland that would exclude Austria. Bismarck formed an alliance with Italy, diverting Austrian forces to the south, while Prussia's modernized army gave them a significant military advantage. The war resulted in a Prussian victory, shifting the balance of power among the German states and leading to the exclusion of Austria from Germany and the unification of the northern German states in the North German Confederation.

What You'll Learn

Otto von Bismarck's expansionist policies
Bismarck's expansionist policies were also influenced by his pragmatic approach to diplomacy and power politics. He understood the importance of alliances and manoeuvred to gain advantages for Prussia, such as in the case of the dispute over the administration of Schleswig-Holstein, which Prussia had conquered from Denmark along with Austria. When Prussia protested an Austrian decision regarding the joint occupation of the region, Bismarck formed an alliance with Italy, committing it to the war if Prussia entered one against Austria within three months. This alliance with Italy, along with Prussia's military strength, resulted in a Prussian victory over Austria in the Seven Weeks' War of 1866, which ended in the exclusion of Austria from Germany and the formation of the North German Confederation under Prussian dominance.
Bismarck's policies were also marked by his opposition to the Catholic Church and the socialist movement. In the 1870s, he allied with the anti-Catholic Liberals and initiated the Kulturkampf ("culture struggle") to disenfranchise and diminish the Polish majority within Prussian-occupied Poland. However, this failed, and he later formed a political alliance with the powerful German Centre Party, which had been formed by Catholics. Bismarck's policies towards the Poles and Catholics, as well as the centralisation of power in his office, drew criticism.
Bismarck's expansionist policies had far-reaching consequences, setting the stage for World War I and ultimately, World War II. His policies unified German states and established Germany as a preeminent power in Europe, but they also stoked nationalist pride and laid the groundwork for future conflicts on the continent. Bismarck's legacy is a reminder of the impact of his expansionist policies and their contribution to shaping the course of European history.

Rivalry over administration of Schleswig-Holstein
The Austro-Prussian War, also known as the Seven Weeks' War, was fought in 1866 between the Austrian Empire and the Kingdom of Prussia, with both sides aided by various allies. Prussia had also formed an alliance with the Kingdom of Italy, linking the conflict to the Third Independence War of Italian unification. The war was part of the wider rivalry between Austria and Prussia and resulted in Prussian dominance over the German states.
The immediate cause of the war was the rivalry over the administration of the duchies of Schleswig and Holstein, which Prussia and Austria had conquered from Denmark and agreed to jointly occupy at the end of the Second Schleswig War in 1864. The crisis began on 26 January 1866, when Prussia protested the decision of the Austrian Governor of Holstein to allow the estates of the duchies to summon a united assembly, claiming that the Austrian decision violated the principle of joint sovereignty. Austria responded on 7 February, arguing that its decision did not infringe upon Prussia's rights in the duchies.
Prussia, led by Chancellor Otto von Bismarck, had ambitions to unite Germany as a "Kleindeutschland" under Prussian rule, excluding Austria. Bismarck played a key role in provoking the conflict over the administration of Schleswig-Holstein. He formed an alliance with Austria during the Second Schleswig War against Denmark, which can be seen as a strategic move to further his expansionist goals. Bismarck considered the annexation of the Duchies crucial for his political survival and sought to portray it as a matter of life and death for Prussia.
The dispute over Schleswig-Holstein escalated when Prussia, confident in its military advantages and having secured French neutrality and Italian support, proposed the abolition of the German Confederation, which was dominated by Austria. Prussia's challenge to Austria's supremacy in the German states was a significant factor in the lead-up to the war. The Prussian troops forced the Austrians out of Schleswig-Holstein, and the war concluded with the Treaty of Prague, which assigned Schleswig-Holstein to Prussia.

Austria's supremacy challenged
Austria's supremacy had been challenged by Prussia since at least 1850, when a war was nearly sparked over Berlin's leadership of the Erfurt Union. Prussia's ambition to unite Germany as a Kleindeutschland under its rule, excluding Austria, further fuelled the rivalry between the two powers.
In the context of the Austro-Prussian War, Prussia, led by Chancellor Otto von Bismarck, challenged Austria's dominance within the German Confederation. Bismarck's vision for Germany was as a dominant and imperial power, reflecting his sense of the superiority of the German race. He sought to divert Austria's forces by forming an alliance with Italy, committing it to the war if Prussia entered one against Austria within three months.
Prussia also took advantage of the fact that other European powers were bound by relations that prevented them from intervening in the conflict. Bismarck had also allegedly secured French neutrality during a meeting with Emperor Napoleon III. This meant that Austria would be fighting without any non-German allies.
The dispute over the administration of the provinces of Schleswig and Holstein, which both Prussia and Austria had conquered from Denmark, became a critical flashpoint. Prussia protested the decision of the Austrian Governor of Holstein to allow the estates of the duchies to convene a united assembly, arguing that it violated the principle of joint sovereignty. Austria countered that its decision did not infringe upon Prussia's rights in the duchies.
The crisis escalated with Prussia's partial mobilization of five divisions along its frontier with Austria, leading to a full-scale war between the two powers. Prussia's modernized army discipline, coupled with the diversion of Austrian forces to the south due to the Italian alliance, resulted in a Prussian victory. The war culminated in the Treaty of Prague, which dissolved the German Confederation and cemented Prussia's dominance over the German states.

Alliance with Italy
The Kingdom of Prussia and the Kingdom of Italy formed an alliance on 8 April 1866, committing Italy to the war if Prussia entered into one against Austria within three months. This alliance was a diplomatic masterstroke by the Prussian Minister President, Otto von Bismarck, who sought to unify Germany under Prussian rule. By allying with Italy, Bismarck was able to divert some of the Austrian forces to the south, giving Prussia a strategic advantage.
The alliance with Italy was significant for Prussia as it ensured that Austria would be fighting on two fronts, with Italian forces engaging Austrian troops in Venetia. This diversion of Austrian forces was crucial in weakening Austria's overall military position and ultimately contributed to Prussia's victory in the war. The timing of the Italo-Prussian alliance was also advantageous as other European powers were unable to intervene due to diplomatic constraints or domestic issues.
The unification of Italy was a key factor in the Italo-Prussian alliance. Italy sought to annex the remaining territories of Emperor Francis Joseph's Kingdom of Lombardy-Venetia, which was under Austrian rule. By allying with Prussia, Italy gained a powerful ally in its quest for unification and expansion. The Italo-Prussian alliance linked the Austro-Prussian War with the Third Independence War of Italian unification, demonstrating the interconnectedness of European politics and conflicts during this period.
The alliance between Prussia and Italy had significant consequences for both the war and the broader geopolitical landscape. Prussia's victory over Austria in the Seven Weeks' War, aided by the alliance with Italy, resulted in a shift of power among the German states. Austria was excluded from its territories in the south and lost political influence in the north, leading to the formation of the North German Confederation under Prussian dominance. The Treaty of Prague, which ended the war, also resulted in territorial gains for Italy, as Austria ceded Venetia, which was then transferred to Italian control.
In conclusion, the alliance between Prussia and Italy was a strategic move by Bismarck to further his goal of unifying Germany under Prussian rule. The alliance had significant military and diplomatic advantages for Prussia, contributing to its victory over Austria and shaping the subsequent unification of Germany. The alliance also benefited Italy in its quest for unification and expansion, demonstrating the complex interplay of interests during the Austro-Prussian War and its impact on the broader European context.

Austria's loss and Prussia's dominance
The Austro-Prussian War, also known as the Seven Weeks' War, was fought between the Austrian Empire and the Kingdom of Prussia in 1866. Prussia was allied with the Kingdom of Italy, linking the conflict to the Italian unification process. The war resulted in Prussian dominance over the German states and a shift in power away from Austrian hegemony. This outcome had significant implications for the future of Germany, contributing to the country's unification under the Prussian Hohenzollern dynasty.
Prussia's victory in the Austro-Prussian War was influenced by several factors. Firstly, Prussia had formed strategic alliances, including a crucial alliance with Italy, which diverted some of the Austrian forces to the south. Additionally, Prussia's modernized army, characterized by its superior discipline, training, and equipment, played a pivotal role in achieving victory. The Prussian army crushed the main Austrian army at the Battle of Sadowa, demonstrating its military prowess.
In contrast, Austria faced challenges in the war. While they were successful in their campaign against Italy, defeating the Italians at the Battle of Custoza and the Battle of Lissa, their focus on the Italian front may have diverted resources and attention from their primary conflict with Prussia. Additionally, Austria's diplomatic position was weakened as they lacked non-German allies, with France remaining neutral and Britain focusing on its domestic affairs. This isolation left Austria without external support against the combined forces of Prussia and Italy.
The consequences of Austria's loss were significant. The Treaty of Prague, signed on August 23, 1866, formally concluded the war. Per the treaty, Austria ceded Venetia, which was subsequently transferred to Italy. Additionally, the German Confederation, which had been under Austrian leadership, was dissolved. Prussia annexed several smaller states, including Schleswig-Holstein, Hanover, Hesse-Kassel, Nassau, and Frankfurt, into the new North German Confederation. This expansion unified all northern German states under Prussian rule and excluded Austria from its territories in the south and political influence in the north.
Prussia's dominance after the war had lasting impacts on the course of German history. The unification of Germany under Prussian leadership contributed to the country's development as a military power, which would later play out during the First and Second World Wars. Chancellor Otto von Bismarck, the Prussian statesman, envisioned a dominant and imperial Germany, and his autocratic instincts and sense of German racial superiority influenced the country's future trajectory.
