East Prussia was a historical region located on the southeastern shore of the Baltic Sea, primarily within present-day Poland and Russia. It was part of the Kingdom of Prussia and later the German Empire, known for its diverse culture and significant agricultural production. The capital city was Königsberg, which played a vital role in trade and education. After World War II, East Prussia was divided between Poland and the Soviet Union, leading to significant demographic changes. The region's German population was largely expelled, and it underwent extensive resettlement. Today, remnants of its history can still be seen in the architecture and cultural influences in the area.
