The Kingdom of Prussia (German: Königreich Preußen) was a German kingdom that constituted the state of Prussia between 1701 and 1918 and included parts of present-day Germany, Poland, Russia, Lithuania, Denmark, Belgium and the Czech Republic. It was the driving force behind the unification of Germany in 1871 and was the leading state of the German Empire until its dissolution in 1918. Although it took its name from the region called Prussia, it was based in the Margraviate of Brandenburg, where its capital was Berlin.

The kings of Prussia were from the House of Hohenzollern. Prussia was a great power from the time it became a kingdom, through its predecessor, Brandenburg-Prussia, which became a military power under Frederick William, known as "The Great Elector". Prussia continued its rise to power under the guidance of Frederick II, more commonly known as Frederick the Great, the third son of Frederick William I. Frederick the Great was instrumental in starting the Seven Years' War, holding his own against Austria, Russia, France and Sweden and establishing Prussia’s role in the German states, as well as establishing the country as a European great power. After the might of Prussia was revealed it was considered as a major power among the German states. Throughout the next hundred years Prussia went on to win many battles. It was because of its power that Prussia continuously tried to unify all the German states under its rule.

After the Napoleonic Wars led to the creation of the German Confederation, the issue of more closely unifying the many German states caused revolution throughout the German states, with each wanting their own constitution. Attempts at creation of a federation remained unsuccessful and the German Confederation collapsed in 1866 when war ensued between its two most powerful member states, Prussia and Austria. The North German Confederation which lasted from 1867–1871, created a closer union between the Prussian-aligned states while Austria and most of Southern Germany remained independent. The North German Confederation was seen as more of an alliance of military strength in the aftermath of the Austro-Prussian War but many of its laws were later used in the German Empire. The German Empire lasted from 1871–1918 with the successful unification of all the German states under Prussian hegemony. This was due to the defeat of Napoleon III in the Franco-Prussian War of 1870–71. The war united all the German states against a common enemy, and with the victory came an overwhelming wave of nationalism which changed the opinions of some of those who had been against unification. In 1871, Germany unified into a single country, minus Austria and Switzerland, with Prussia the dominant power.
