Where does Prussia come from?

Prussia originated as a region inhabited by the Baltic Prussians, a group of pagan tribes, in what is now northeastern Poland and the Kaliningrad Oblast of Russia. In the 13th century, the Teutonic Knights, a Catholic military order, conquered the area and established the State of the Teutonic Order. Over time, the region evolved into the Duchy of Prussia, which became a Protestant state in the 16th century, and later transformed into the Kingdom of Prussia in 1701, playing a significant role in European history and the unification of Germany. Prussia ultimately ceased to exist as a political entity after World War II, when its territories were divided between Poland, Russia, and other nations.
