Joanna's marriage was celebrated in Switzerland, where Baden's court stayed in exile due to repeated French invasions.

[1] Two months later in Stuttgart, the marriage of Eberhard Ludwig's sister, Magdalene Wilhelmine and the crown prince and later Margrave Charles III Wilhelm of Baden-Durlach was celebrated.

It was important for him to command a standing army and a great role model and lead to an absolutist French state with a brilliant court.

On the application of Johanna Elisabeth to Holy Roman Emperor Charles VI, the bigamous marriage had to be dissolved and Grävenitz was sent into exile in Switzerland.

Because of this danger, Duke Eberhard Ludwig broke his connection to Wilhelmine of Grävenitz and hoped to conceive an heir from his legitimate and long-ignored wife, Johanna Elisabeth.
