The purpose was to depose the de jure regent Duke Charles and the de facto regent Gustaf Adolf Reuterholm, leaders of the regency government of Gustav IV Adolf of Sweden, and replace them with Gustaf Mauritz Armfelt, the favorite of the king's father Gustav III of Sweden.
On his deathbed, King Gustav III had also committed the care of his son to Gustaf Mauritz Armfelt and appointed him a member of the Privy Council and Governor of Stockholm.
[6][1][4] Soon after the murder of Gustav III, Gustaf Adolf Reuterholm was recalled from his exile by Duke Charles and made president of the Kammarrevisionen (a forerunner of the Administrative court of appeal).
This plan did not receive support at a sufficiently high level in Catherine's court, but Reuterholm's spies in Italy intercepted some of Armfelt's letters.
[6][1][4] Armfelt was convicted in his absence by Svea Court of Appeal on 22 July 1794 to forfeit his life, all honours and possessions, guilty of planning an armed coup.
