Joakim von Anckarström was a Swedish nobleman born in 1762. He is most famously known for assassinating King Gustav III of Sweden in 1792. Anckarström was motivated by political reasons, as he opposed the king's autocratic rule and sought to restore parliamentary power. After the assassination, Anckarström was captured, tried, and executed for his crime. His actions had significant consequences for Sweden, leading to increased repression and a shift in the political landscape. The event remains a notable moment in Swedish history, illustrating the tensions between monarchy and democracy during that period.
