His parents separated after a marriage that had been turbulent for years and the mother retreated to Kassel. As a result, Charles grew up without a mother under the eyes of his authoritarian father. Charles's younger sister Elizabeth Charlotte ("Liselotte") was married in 1671 to the brother of King Louis XIV of France, Philippe I, Duke of Orléans.
The prince's education was led by the scholars Samuel von Pufendorf and Ezekiel Spanheim. Charles undertook his cavalier tour to Switzerland and France in 1670. In Switzerland, Karl fell ill with smallpox, which permanently disfigured his face.
In 1671, he married through his aunt Sophia of Hanover's mediation Princess Wilhelmine Ernestine of Denmark, a daughter of King Frederick III of Denmark and Sophie Amalie of Brunswick-Lüneburg, in Heidelberg. The marriage became unhappy and remained childless.[1] Sophia later wrote about it in her memoirs: “The Electoral Prince, who had a very reserved upbringing, asked the Duke (Sophia's husband Ernest Augustus) to give him his advice in matters that he knew nothing about. But he seems to have been a bad student, because his wife never became pregnant.“[2]
Rule
His short reign was not glamorous. He appointed his incompetent former tutor Paul Hachenberg as chief minister, leaving his half-siblings, the "Raugraves", out of favour. He brought back his mother from Kassel and paid her immense debts. Charles was of a weak and timid nature, marked by familial childhood experiences. He showed a superficial enthusiasm for military life. Charles was a strict Calvinist. The court preacher Johann Ludwig Langhanns became senior minister after Hachenberg's death.
Increasing financial difficulties in the state budget, caused by oversized households, passion for hunting and theater as well as military spending, could no longer be regulated by tax increases. In 1682, Charles pledged Germersheim to France for twenty years. He liked to stage expensive theatrical re-enactments of battles with sieges, ships, etc. and within a few years wasted the national treasury that his father had saved over many years.
