Mecklenburg-Vorpommern is a state in the northeast of the Federal Republic of Germany with more than 1.6 million inhabitants. The capital is Schwerin. As early as 1945, a state of the same name was formed in the Soviet occupation zone from the state of Mecklenburg, which had been united in 1934, the previously Prussian Vorpommern and the Amt Neuhaus, which had previously belonged to the Prussian province of Hanover. From 1947, the state was officially known only as Mecklenburg County, and it was dissolved again as early as 1952. It was not until German reunification in 1990 that the state of Mecklenburg-Vorpommern was re-established.

After the Thirty Years' War (Peace of Westphalia in 1648), Western Pomerania initially became Swedish, and Western Pomerania fell to Brandenburg, which was able to acquire further parts of Western Pomerania in 1720. It was not until 1815 that the entire region belonged to the Kingdom of Prussia as the Province of Pomerania. The province existed until the end of World War II, its capital was Szczecin (today Polish: Stettin).
