"Gustafs skål", literally Toast to Gustav, is a song written by Carl Michael Bellman as a salutation to Gustav III of Sweden, following the coup d'etat of 1772, which made himself an autocrat and ended the parliamentary age of liberty.
He also wrote lengthy memoirs under the title Lefnadsjournaler, which finally totalled some 11,000 folio pages and are often detailed descriptions of society, his own deeds, naval battles and the performance of the Gustafs skål on revolution-night, 19 August 1772, in honour of Gustav III of Sweden.
