3 Population estimates:[1]

Prussia (German: Preußen, Polish: Prusy, Lithuanian: Prūsija) was the name for a place in Northern Europe. It was part of Germany for a while, and included land in Poland, too. The name "Prussian" has had a lot of different meanings in the past and now:

In 1934 the Nazis stopped using the name Prussia for that area, and in 1947 the Allies abolished the state of Prussia, and divided its territory among themselves and the new States of Germany. Today the name is only for historical, geographical, or cultural use.

The name Prussia is from the Borussi or Prussi people who lived in the Baltic region and spoke the Old Prussian language. Ducal Prussia was a fiefdom of the Kingdom of Poland until 1660, and Royal Prussia was part of Poland until 1772. In the late eighteenth and early nineteenth centuries, most German-speaking Prussians started thinking they were part of the German nation. They thought the Prussian way of life was very important:

  • Perfect organization
  • Sacrifice (giving other people something you need)
  • Obeying the law

From the late 18th century, this bigger Prussia had a lot of power in North Germany; it was the strongest in politics and economics, and it had the most people. In 1871 Otto von Bismarck created the German Empire, and Prussia was the center of the empire.


Prussia was a small part of today’s northern Poland. After a small number of Prussi people lived there, Germans came to live there too. In 1934, Germany’s borders were with France, Belgium, the Netherlands, and Lithuania. Some parts of Prussia can be found in eastern Poland. Before 1918, a lot of western Poland was also in Prussia. Between 1795 and 1807, Prussia also controlled Warsaw and most of central Poland.

Before 1934, these regions were also in Prussia:

However, some regions were never part of Prussia, such as Oldenburg, Mecklenburg, and the Hanse city-states.

North-east Germany was Protestant, so Prussians were mostly Protestant. But there were a lot of Catholic people in the Rhineland, East Prussia, Posen, Silesia, West Prussia, and Ermland. The states of south Germany (especially Austria and Bavaria) were Catholic, so they did not want Prussia to have the power. Prussia was mostly German, but in the late 18th century the new Polish areas had a lot of Polish people too. In 1918, these Polish areas returned to Poland.
