The Anjala League (Swedish: Anjalaförbundet, Finnish: Anjalan liitto) of 1788 was a scheme by disgruntled Swedish officers to end Gustav III's Russian War of 1788–1790. Declaring Finland an independent state was not a part of the original plot, but one of the conspirators Johan Anders Jägerhorn, who handed the note to Empress Catherine the Great, made such claims in Saint Petersburg.
