King Charles X of Sweden

1. Charles X Gustav, also Carl Gustav (Swedish: Karl X Gustav; 8 November 1622 – 13 February 1660), was King of Sweden from 1654 until his death. He was the son of John Casimir, Count Palatine 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.

2. In his early childhood, raised in the Swedish court alongside his cousin Queen Christina, he received an excellent civil education. Later Charles X learned the art of war under Lennart Torstenson, being present at the second Battle of Breitenfeld (1642) and at Jankowitz (1645). From 1646 to 1648 he frequented the Swedish court, supposedly as a prospective husband of his cousin the queen regnant, Christina of Sweden (1626–89, reigned 1632–54), but her insurmountable objection to wedlock put an end to these anticipations, and to compensate her cousin for a broken half-promise she declared him her successor in 1649, despite the opposition of the Privy Council headed by Axel Oxenstierna.

3. In 1648 he gained the appointment of commander of the Swedish forces in Germany. The conclusion of the treaties of Westphalia in October 1648 prevented him from winning the military laurels he is said to have desired, but as the Swedish plenipotentiary at the executive congress of Nuremberg, he had an opportunity to learn diplomacy, a science he is described as having quickly mastered. As the recognized heir to the throne, his position on his return to Sweden was dangerous because of the growing discontent with the queen. He therefore withdrew to the isle of Öland until the abdication of Christina on 5 June 1654 called him to the throne.

4. Charles Gustav was crowned on 7 June 1654, the day after his cousin Christina abdicated. The beginning of Charles X's reign concentrated on the healing of domestic discords and on the rallying of all the forces of the nation round his standard for a new policy of conquest.[citation needed] On the recommendation of his predecessor, he contracted a political marriage on 24 October 1654 with Hedwig Eleonora, the daughter of Frederick III, Duke of Holstein-Gottorp. He was hoping to secure a future ally against Denmark. The Riksdag which assembled at Stockholm in March 1655, duly considered the two great pressing national questions: war, and the restitution of the alienated crown lands.

5. War in Poland-Lithuania On 10 July 1655, Charles X left Sweden to engage in a war against the Polish-Lithuanian Commonwealth, in what became the Second (or Little) Northern War (1655–1660). By the time war was declared he had at his disposal 50,000 men and 50 warships. Hostilities had already begun with the occupation of Dünaburg in Polish Livonia by the Swedes on 1 July 1655. Then on 21 July 1655 Swedish army under Arvid Wittenberg crossed into Poland and proceeded towards the encampment of the Greater Poland Levy of the Nobility (pospolite ruszenie) encamped among the banks of the Noteć river, with some regular infantry for support. On 25 July the Polish noble levy army capitulated, and the voivodeships of Poznań and Kalisz placed themselves under the protection of the Swedish King.

6. Thereupon the Swedes entered Warsaw without opposition and occupied the whole of Greater Poland. The Polish king, John II Casimir of Poland (1648–68) of the House of Vasa, eventually fled to Silesia after his armies had suffered defeats. A great number of Polish nobles and their personal armies joined the Swedes, including the majority of the famous Winged Hussars. Many Poles saw Charles X Gustav as a strong monarch who could be a more effective leader than John II Casimir. Charles X in skirmish with Tatars near Warsaw

7. Triumph of Charles X Gustavus over the Polish- Lithuanian Commonwealth (c. 1655) Russians signed a cease- fire with the Polish- Lithuanian Commonwealth (Treaty of Vilno of 1656 ) and then pursued a campaign in Livonia and laid siege to Riga, the second largest city in the Swedish Realm.

8. War on Denmark-Norway Labiau involved an essential modification of Charles's Baltic policy; but the alliance with the elector of Brandenburg had now become indispensable for him on almost any terms. The difficulties of Charles X in Poland are believed to have caused him to receive the tidings of the Danish-Norwegian declaration of war on 1 June 1657 with extreme satisfaction. He had learnt from Torstensson that Denmark was most vulnerable if attacked from the south, and he attacked Denmark with a velocity which paralysed resistance. At the end of June 1657, at the head of 8,000 seasoned veterans, he broke up from Bromberg (Bydgoszcz) south of Pomerania and reached the borders of Holstein on 18 July. The Danish army dispersed and the Swedes recovered the duchy of Bremen.

9. In the early autumn Charles's troops swarmed over Jutland and firmly established themselves in the duchies. But the fortress of Fredriksodde (Fredericia) held Charles's smaller army at bay from mid-August to mid- October, while the fleet of Denmark, after two days’ battle, compelled the Swedish fleet to abandon its projected attack on the Danish islands. The position of the Swedish king had now become critical. In July Denmark-Norway and Poland-Lithuania concluded an offensive and defensive alliance. Still more ominously for the Swedes, the elector of Brandenburg, perceiving Sweden's difficulties, joined the league against Sweden and compelled Charles to accept the proffered mediation of Oliver Cromwell, Coenraad van Beuningen and Cardinal Mazarin.

10. The negotiations foundered, however, upon the refusal of Sweden to refer the points in dispute to a general peace-congress, and Charles received encouragement from the capture of Fredriksodde, 23-24 October, whereupon he began to make preparations for conveying his troops over to Funen in transport vessels. But soon another and cheaper expedient presented itself. In the middle of December 1657 began the great frost, which would prove so fatal to Denmark-Norway. In a few weeks the cold had grown so intense that the freezing of an arm of the sea with so rapid a current as the Small Belt became a conceivable possibility; and henceforth meteorological observations formed an essential part of the strategy of the Swedes.

11. The crossing of the Great Belt On 28 January 1658, Charles X arrived at Haderslev in South Jutland. His meteorologists estimated that in a couple of days the ice of the Little Belt would become firm enough to bear even the passage of a mail-clad host. On the night of 5 February the transit began, the cavalry leading the way through the snow- covered ice, which quickly thawed beneath the horses’ hoofs so that the infantry which followed after had to wade through half an ell (nearly 2 feet) of sludge, facing the risk that the ice would break beneath their feet. Charles reached Falster. On 11 February he stood safely on the soil of Zealand.

12. On 17 July he again landed on Zealand and besieged Copenhagen with its king Frederick III of Denmark, but Copenhagen repelled a major assault and managed to hold out long enough for the Dutch fleet under Lieutenant- Admiral Jacob van Wassenaer Obdam to relieve the city, defeating the Swedish fleet in the Battle of the Sound on 29 October 1658. Jutland had been reconquered by Denmark-Norway's allies, Poland and Brandenburg, and in 1659 Danish and forces liberated the Island of Funen in the Battle of Nyborg. As Baltic trade was vital to the Dutch economy they made clear to Charles they wouldn't allow Sweden to control the Sound.

13. Illness and death Soon after the estates opened on 4 January 1660, Charles X Gustav fell ill with symptoms of a cold. Ignoring his illness, he repeatedly went to inspect the Swedish forces near Gothenburg, and soon broke down with chills, headaches and dyspnoea. On 15 January, court physician Johann Köster arrived, and in medical error mistook Charles X Gustav's pneumonia for scorbut and dyspepsia. Köster started a "cure" including the application of multiple enemata, laxatives, bloodletting and sneezing powder. While after three weeks the fever eventually was down and the coughing was better, the pneumonia had persisted and evolved into a sepsis by 8 February. On 12 February, Charles X Gustav signed his testament: His son, Charles XI of Sweden, was still a minor, and Charles X Gustav appointed a minor regency consisting of six relatives and close friends. Charles X Gustav died the next day at the age of 37

14. Charles XI, also Carl (Swedish: Karl XI) (24 November 1655 – 5 April 1697 Family Charles X had one legitimate child by Hedwig Eleonora of Holstein- Gottorp: his successor Charles XI (1655–1697, reigned 1660–1697). By Märta Allertz he had an illegitimate son: Gustaf Carlson (1647–1708), who became Count of Börringe and Lindholmen Castle in Scania. Hedwig Eleonora of Holstein- Gottorp (23 October 1636 – 24 November 1715) was Queen of Sweden from 1654 until 1660 by marriage to Charles X He also had a number of other children, by different women, before his marriage.
