Swedish king Adolf Frederick died on this day in 1771. The cause of his death was allegedly overeating.
Namely, the king died after a particularly lavish meal of lobster, caviar, sauerkraut, smoked herring, and champagne. In addition, he allegedly ate 14 pieces of a specific type of Swedish brioche (semla), served in a bowl of hot milk.
The king was 60 years old at the moment of his death, and had ruled Sweden for almost 20 years. He was married to Louisa Ulrika of Prussia, the sister of the famous Prussian king Frederick II the Great (arch-rival of Empress Maria Theresa).
As the Swedish king, Adolf Frederick was not particularly active in politics, but was more devoted to other pursuits (collecting snuff boxes was allegedly a big hobby of his).
