It is a historical place name in Europe, located in northern Germany, and generally refers to the Prussian kingdom between17th century and19th century. It is the most powerful state in Germany. /kloc-in the 9th century, Germany was unified through three dynastic wars, France was defeated in the Franco-Prussian War of 187 1, and William I was crowned Emperor of the German Empire at Versailles. It is a powerful military empire, which rose and unified Germany in just 200 years and established the Second Reich of Germany. So Prussia is sometimes synonymous with modern German spirit and culture, and also the source of German brickism and militarism.
Now Prussia no longer exists in the administrative area:
Germany was defeated in World War I and was forced to sign the Treaty of Versailles, ceding alsace-lorraine to France, Auburn-Marmedi to Belgium, North Schleswig to Denmark and West Prussia-Posen to Poland. But Jersey is under the jurisdiction of the League of Nations, and East Prussia and Germany are separated from each other.
During World War II, West Prussia was located between East Prussia and Germany (that is, the Polish Corridor), separating East Prussia from Germany. After World War II, East Prussia was divided between Poland and the Soviet Union.
