She had been brought up at the ducal court of Brunswick at Wolfenbüttel Castle by her godmother and aunt by marriage, Elisabeth Sophie Marie, the wife of Augustus William, Duke of Brunswick-Lüneburg, to whom the duke of Holstein-Gottorp was glad to relinquish one of his several daughters. Johanna Elisabeth grew up on the same footing as her cousin, the duchess's daughter, and it was the duchess who arranged her marriage at 15 and provided her dowry.

Title: Joanna Elisabeth of Holstein-Gottorp
Content:  Johanna Elisabeth found her existence with her sober, middle-aged husband in Stettin a far cry from the livelier atmosphere she had grown up in at the court of Brunswick. The city offered little scope for a young girl like Johanna Elisabeth, who craved for an exciting social life. Neither did the birth of her first child bring her much joy. Her attitude toward Sophie (the future Empress Catherine II) was always ambivalent. The birth was a difficult one, and Joanna Elisabeth seems to have thought that the reward was insufficient, considering what she went through. According to her daughter, she nearly died in the process, and it took her 19 weeks to recover. The reigning Prince of Anhalt-Zerbst, cousin of Christian August, apparently could not have children and his older brother, Louis,

Content:  In 1747, she was widowed and became regent of Anhalt-Zerbst until 1752, in place of her minor son Frederick Augustus. She had the new palace at Dornburg (near Gommern) built as from 1750, a lavish baroque palace prepared to host her brother, Adolf Frederick, King of Sweden, or her daughter, the future empress, however, neither of them ever visited, and the dowager princess and her son were forced into exile when Prussian forces invaded Anhalt-Zerbst during the Seven Years' War in 1758. Frederick the Great, who had made the princess' late husband a governor and field marshal in 1742, and who had taken part in the diplomatic arrangement of her daughter's Russian marriage in 1744, accused the princess and her son of ungratefully supporting Russia against himself as Empress Elizabeth was now his war enemy. Johanna Elisabeth died at age 47 at Paris, France in 1760. Her daughter became empress of Russia in 1762. Her son, Frederick Augustus, never returned to Zerbst and continued to live in Basel and Luxemburg, while he had stewards governing his principality and transferring him its revenues.

Content:  When her brother Adolf Frederick was chosen to succeed to the throne of Sweden, Johanna Elisabeth began to forge the idea to marry her daughter to a party of high rank.

Content:  unmarried: This meant that if Johanna Elisabeth would have given her husband a son, their family's position would have changed considerably, and she would have been able to leave Stettin forever. Later, Johanna Elisabeth's priority thus remained the political advancement of her children and to give them a more distinguished future than she had, being forced to marry a prince with little prospect despite being the great-granddaughter of a king of Denmark. However, she always wanted to be a step ahead of her daughter, constantly feeling jealous of her and wanting to put her down, to the extent that she even allowed her brother, Georg Ludwig of Holstein-Gottorp to openly display his strong liking for Sophie, so much so that he kissed her on the lips. Infatuated by Sophie, Georg Ludwig proposed
