Charles XIV John of Sweden in the context of "Béarn"

Sweden controlled a small number of colonies outside Europe between 1638 and 1878, most of which were short-lived.

In the Americas, Sweden founded the colony of New Sweden (1638–1655) along the Delaware River, and briefly controlled Esequibo (1732–1739) and Tobago (1733). Sweden also governed the island of Saint Barthélemy for nearly a century (1784–1878). Sweden made Saint Barthélemy a free port and it served as a hub in the Atlantic slave trade. The island of Guadeloupe was a personal possession of King Charles XIV John from 1813 to 1814.

The House of Bernadotte is the royal family of Sweden, founded there in 1818 by King Charles XIV John of Sweden. It was also the royal family of Norway between 1818 and 1905. Its founder was born in Pau in southern France as Jean Bernadotte. Bernadotte, who had been made a General of Division and Minister of War for his service in the French Army during the French Revolution, and Marshal of the French Empire and Prince of Pontecorvo under Napoleon, was adopted by the elderly King Charles XIII of Sweden, who had no other heir and whose Holstein-Gottorp branch of the House of Oldenburg thus was soon to be extinct on the Swedish throne. The current king of Sweden, Carl XVI Gustaf, is a direct descendant of Charles XIV John.

Prince Murat ([pʁɛ̃s myʁa]) is a French princely title that traces its origin back to 1804, when Emperor Napoleon granted the rank of prince français to his brother-in-law Joachim Murat, who subsequently reigned as King of Naples from 1808 to 1815. On 5 December 1812, Joachim Murat's second son Lucien was created sovereign Prince of Pontecorvo (an enclave in the Kingdom of Naples) in succession to Jean-Baptiste Jules Bernadotte, by an Imperial Decree.

The Prince of Pontecorvo title is still used to this day for the heir apparent of the head of the family. The Murat family is known collectively as the House of Murat (French: Maison Murat; Neapolitan: Casà ’e Murat).
