The region of Pomerelia at the eastern end of Pomerania, including Gdańsk (Danzig), was ruled in the 12th and 13th centuries by the Samborides , who were (at least initially) more closely tied to the Kingdom of Poland than were the Griffins. After the death of the last Samboride in 1294, the region was ruled by kings of Poland for a short period, although also claimed by Brandenburg . After the Teutonic takeover in 1308 the region became part of the monastic state of the Teutonic Knights . In the Second Peace of Thorn (1466) most of the region became part of Royal Prussia within the Kingdom of Poland, as it remained until being acquired by the Kingdom of Prussia in the partitions of 1772 and 1793. A small area in the west of Pomerelia, the Lauenburg and Bütow Land (the region of Lębork and Bytów ) was granted to the rulers of Pomerania, although it remained a Polish fief until the First Partition . (A large part of Pomerelia formed the Polish Corridor between the World Wars, and so was not part of the post-war Recovered Territories.)
As West Germany was reorganised and gained independence from its occupiers, the German Democratic Republic was established in East Germany in 1949. The creation of the two states solidified the 1945 division of Germany.  On 10 March 1952, (in what would become known as the " Stalin Note ") Stalin put forth a proposal to reunify Germany with a policy of neutrality, with no conditions on economic policies and with guarantees for "the rights of man and basic freedoms, including freedom of speech, press, religious persuasion, political conviction, and assembly" and free activity of democratic parties and organizations.  This was turned down; reunification was not a priority for the leadership of West Germany, and the NATO powers declined the proposal, asserting that Germany should be able to join NATO and that such a negotiation with the Soviet Union would be seen as a capitulation. There have been several debates about whether a real chance for reunification had been missed in 1952.
