The
Coup of 1809 also referred to as the
Revolution of 1809 (Swedish:
Revolutionen 1809) was a Swedish
coup d'état by a group of noblemen resulting in the deposition of King
Gustav IV Adolf of Sweden and the introduction of the
Instrument of Government (1809). The coup was provoked by the disastrous
Finnish War. The leaders of the coup are known in history collectively as
1809 års män (the Men of 1809).
