The Baltic Sea has been a vital trade route for centuries, connecting Northern Europe with the rest of the world. Major ports like Gdańsk, Stockholm, and Helsinki facilitate the exchange of goods such as timber, grain, and fish. The sea's strategic location allows for efficient shipping and transportation, benefiting countries like Sweden, Finland, and Poland. Trade in the Baltic Sea region has evolved over time, influenced by historical events and economic changes. The Hanseatic League, a medieval trading alliance, played a significant role in promoting commerce among cities around the sea. Today, the Baltic Sea remains crucial for international trade, supporting both local economies and global markets.
