The Duchy of Pomerania was a duchy in Pomerania on the southern coast of the Baltic Sea, ruled by dukes of the House of Pomerania (Griffins). The country existed in the Middle Ages between years 1121–1160, 1264–1295, 1478–1531, and 1625–1637.
The House of Griffin or Griffin dynasty was a dynasty ruling the Duchy of Pomerania from the 12th century until 1637. The name "Griffins" was used by the dynasty after the 15th century and had been taken from the ducal coat of arms. Duke Wartislaw I was the first historical ruler of the Duchy of Pomerania and the founder of the Griffin dynasty. The most prominent Griffin was Eric of Pomerania, who became king of the Kalmar Union in 1397, thus ruling Denmark, Sweden and Norway. The last Griffin duke of Pomerania was Bogislaw XIV, who died during the Thirty Years' War, which led to the division of Pomerania between Brandenburg-Prussia and Sweden. Duchess Anna von Croy, daughter of Duke Bogislaw XIII and the last Griffin, died in 1660.
Eric II or Erich II was a member of the House of Pomerania and was the ruling Duke of Pomerania-Wolgast from 1457 to 1474. He was the son of Wartislaw IX of Pomerania-Wolgast and Sophia, daughter of Eric IV of Saxe-Lauenburg.
Treaty of Prenzlau or Peace of Prenzlau may refer to several treaties during a series of wars between the Margraviate of Brandenburg and the Duchy of Pomerania fought for control of Pomerania-Stettin, and possession of the Uckermark in the 15th century. The First Peace of Prenzlau ended a war fought between 1445 and 1448, while the Second Peace of Prenzlau ended a war fought between 1466 and 1468. In older documents, Prenzlau may be spelled Prenzlow, which was the common spelling during the time period the treaties were drawn and was only changed during the 19th century. Prenzlau is situated in the center of Uckermark.

The Duchy of Pomerania-Stolp, also known as the Duchy of Stolp, and the Duchy of Słupsk, was a feudal duchy in Farther Pomerania. Its capital was Słupsk. It was ruled by the Griffin dynasty. It existed in the High Middle Ages era from 1368 to 1478.
The Duchy of Pomerania was partitioned several times to satisfy the claims of the male members of the ruling House of Pomerania dynasty. The partitions were named after the ducal residences: Pomerania-Barth, -Demmin, -Rügenwalde, -Stettin, -Stolp, and -Wolgast. None of the partitions had a hereditary character, the members of the House of Pomerania inherited the duchy in common. The duchy thus continued to exist as a whole despite its division. The only exception was made during a war with the Margraviate of Brandenburg, when in 1338 Barnim III of Pomerania-Stettin was granted his partition as a fief directly from the Holy Roman Emperor, while Pomerania-Wolgast remained under formal Brandenburgian overlordship. However, already in 1348, German king and later emperor Charles IV again granted the Duchy of Pomerania as a whole and the Principality of Rügen as a fief to the dukes of both Pomerania-Stettin and Pomerania-Wolgast, nullifying Brandenburg's claims by granting Imperial immediacy.
The Treaty of Soldin was signed on 21 January 1466 at Soldin by the Brandenburgian elector Frederick II and the Pomeranian dukes Eric II and Wartislaw X. It was mediated by the town of Stettin. The treaty temporarily settled a conflict about the succession of Otto III, Duke of Pomerania, who had died without issue: Emperor Frederick III, elector Frederick II as well as Eric II and Wartislaw X of Pomerania claimed to be the rightful heir of Otto's share of the Duchy of Pomerania.
Starting in the 12th century, the Margraviate, later Electorate, of Brandenburg was in conflict with the neighboring Duchy of Pomerania over frontier territories claimed by them both, and over the status of the Pomeranian duchy, which Brandenburg claimed as a fief, whereas Pomerania claimed Imperial immediacy. The conflict frequently turned into open war, and despite occasional success, none of the parties prevailed permanently until the House of Pomerania died out in 1637. Brandenburg would by then have naturally have prevailed, but this was hindered by the contemporary Swedish occupation of Pomerania, and the conflict continued between Sweden and Brandenburg-Prussia until 1815, when Prussia incorporated Swedish Pomerania into her Province of Pomerania.
The Treaty of Pyritz settled claims of the House of Pomerania and the House of Hohenzollern regarding the legal status and succession in the Duchy of Pomerania on 26 and 28 March 1493. John Cicero, Elector of Brandenburg of the Hohenzollern renounced the Electorate of Brandenburg's claims to hold the Pomeranian duchy as a fief on 26 March in Pyritz. In turn, Bogislaw X, Duke of Pomerania acknowledged Brandenburgian succession in his duchy in case of the extinction of his dynasty on 28 March in Königsberg. The treaty was the most important achievement of Bogislaw X's foreign policy. It was confirmed and amended when a final settlement between the two houses was reached in the Treaty of Grimnitz in 1529.
Duke Casimir V of Pomerania was a member of the House of Griffins and a Duke of Pomerania. He ruled in Pomerania-Stettin together with his brother Otto II from 1413 to 1428. After 1428, he ruled Pomerania-Stettin alone.
