Long ago, two groups fought a war. 
Long ago, France and Prussia fought a war. 


In 1870, a big war began between France and Prussia. 

A disagreement about a prince led to the fight. Bismarck used a telegram to make France angry. This caused France to declare war in July 1870. The German side had many advantages. They had more soldiers and better training. They also used new tools like trains and big guns.
The German armies won many battles. They even captured the French Emperor, Napoleon III. The war continued as German troops surrounded Paris. The city fell in early 1871. This victory helped create the German Empire. 
The Franco-Prussian War was a major conflict in Europe. It lasted from July 19, 1870, to January 28, 1871. 


The war began because of a disagreement over a throne. A prince from the Hohenzollern family was offered the Spanish throne. France feared this would give Prussia too much power near its borders. 
Fighting happened in several stages across the land. The German forces were very well prepared for the fight. They had more soldiers and better training than the French. 

Even after the Emperor was caught, the war continued. A new Government of National Defense was formed in Paris. 

The war changed the map of Europe forever. In May 1871, leaders signed the Treaty of Frankfurt. 
The Franco-Prussian War was a major military conflict in Europe. It lasted from July 19, 1870, to January 28, 1871. 

The war began due to a diplomatic crisis regarding the Spanish throne. A prince from the Hohenzollern-Sigmaringen family was offered the position. France feared this would leave them surrounded by Prussian influence. Although the prince eventually withdrew his acceptance, tensions remained very high. 
Bismarck had specific goals for this conflict. Many historians believe he wanted to provoke France into declaring war. He hoped a shared enemy would unite the independent southern German states. These states included Baden, Württemberg, Bavaria, and Hesse-Darmstadt. By fighting alongside Prussia, these states would likely join a unified German nation. France mobilized its army on July 15, 1870. The North German Confederation responded with its own mobilization that same night. France officially declared war on July 19, 1870. The southern German states immediately joined the Prussian side.
The war unfolded in distinct military phases. The German coalition possessed significant advantages in organization and technology. They used railways to move troops with great speed. They also utilized advanced artillery, which are large-caliber guns used in combat. German forces were superior in numbers and professional training. 

Following the defeat at Sedan, the war entered a second phase. A new Government of National Defense was established in Paris. This new government continued to fight for five more months. German troops engaged new French armies in northern France. Eventually, the German military began a siege of Paris. A siege is a military operation where an army surrounds a city to cut off supplies. The siege lasted for over four months. Paris finally fell on January 28, 1871. This marked the effective end of the war. 
The conclusion of the war led to massive political changes. As German victory became certain, the German states proclaimed the creation of the German Empire. King Wilhelm I became the first German Emperor. This unified most German-speaking people under one nation-state for the first time. In May 1871, the Treaty of Frankfurt was signed. 

The war had long-lasting effects on French society and politics. The defeat ended imperial rule in France. This led to the establishment of the French Third Republic. The war also caused deep resentment within France. This anger contributed to the Paris Commune, a revolutionary uprising in Paris. The Commune held power for two months before it was suppressed. On the international stage, Bismarck used his influence to shape European affairs for twenty years. His approach was known as Realpolitik, which focuses on practical power and national interest. The war fundamentally shifted the balance of power in Europe for decades to come.
