Christina of Sweden in the context of "Catherine of Sweden (1584-1638)"

Swedish Pomerania (Swedish: Svenska Pommern; German: Schwedisch-Pommern) was a dominion of Sweden from 1630 to 1815 on what is now the Baltic coast of Germany and Poland. Following the Polish War and the Thirty Years' War, Sweden held extensive control over the lands on the southern Baltic coast, including Pomerania and parts of Livonia and Prussia (dominium maris baltici).

Sweden, which had been present in Pomerania with a garrison at Stralsund since 1628, gained effective control of the Duchy of Pomerania with the Treaty of Stettin in 1630. At the Peace of Westphalia in 1648 and the Treaty of Stettin in 1653, Sweden received Western Pomerania (German Vorpommern), with the islands of Rügen, Usedom, and Wolin, and a strip of Farther Pomerania (Hinterpommern). The peace treaties were negotiated while the Swedish queen Christina was a minor, and the Swedish Empire was governed by members of the high aristocracy. As a consequence, Pomerania was not annexed to Sweden like the French war gains, which would have meant abolition of serfdom, as the Pomeranian peasant and shepherd regulation of 1616 was practised there in its most severe form. Instead, it remained part of the Holy Roman Empire, making the Swedish rulers Reichsfürsten (imperial princes) and leaving the nobility in full charge of the rural areas and its inhabitants. While the Swedish Pomeranian nobles were subjected to reduction when the late 17th-century kings regained political power, the provisions of the peace of Westphalia continued to prevent the pursuit of the uniformity policy in Pomerania until the Holy Roman Empire was dissolved in 1806.

The American Swedish Historical Museum is the oldest Swedish-American museum in the United States. It is located in Franklin Delano Roosevelt Park in South Philadelphia, on part of a historic 17th-century land grant originally provided by Queen Christina of Sweden to settlers of New Sweden.

Charles X Gustav, also Carl X Gustav (Swedish: Karl X Gustav; 8 November 1622 – 13 February 1660), was King of Sweden from 1654 until his death in 1660. He was the son of John Casimir, Count Palatine (Pfalzgraf) of Zweibrücken-Kleeburg, and Catherine of Sweden. After his father's death, he also succeeded him as Pfalzgraf. He was married to Hedwig Eleonora of Holstein-Gottorp, who bore his son and successor, Charles XI. Charles X Gustav was the second Wittelsbach king of Sweden after the childless king Christopher of Bavaria (1441–1448) and he was the first king of the Swedish Caroline era, which had its peak during the end of the reign of his son, Charles XI. He led Sweden during the Second Northern War, enlarging the Swedish Empire. By his predecessor Christina, he was considered de facto Duke of Eyland (Öland), before ascending to the Swedish throne. From 1655 to 1657, he also claimed the title of Grand Duke of Lithuania.

His numbering as Charles X derives from a 16th-century invention. One of his predecessors, Charles IX (1604–1611), chose his numeral after studying a fictitious history of Sweden. Charles X Gustav was the fourth actual King Charles, but has never been called Charles IV.
