Upon the illness of the king in Brandenburg during the campaign of 1719, he sent for Sophia Dorothea and entrusted her with his will, cautioning secrecy. Within the document, she was named regent during the minority of their son, with Charles VI, Holy Roman Emperor, and King George I of Great Britain as guardians to the Crown Prince. The king's favorites, military general Friedrich von Grumbkow and Leopold I of Anhalt-Dessau, offered the queen's favorite Madame de Blaspiel a bribe if she procured information for them and influenced the queen in their favor; she in turn informed the queen, who informed the king, who summoned von Grumbkow and the Prince and told them to return to Berlin. They then tasked Madame de Blaspiel's lover, Count de Manteufel, the Saxon ambassador, to acquire the document or at least find out its meaning: the queen did give de Blaspiel the document, and its contents were revealed to Grumbkow and Anhalt. Grumbkow and Anhalt, now wishing to lessen the queen's influence after learning of the will appointing her regent, unsuccessfully tried to accuse her before the king of having borrowed money and pawning a pair of earrings given to her by the king to pay her gambling debts. The queen countered by accusing Grumbkow of plotting against her.
