Which Swedish king supposedly died after eating too much food?

Adolf Frederick or Adolph Frederick (Swedish: Adolf Fredrik, German: Adolf Friedrich; 14 May 1710 – 12 February 1771) was King of Sweden from 1751 until his death. He was the son of Christian August of Holstein-Gottorp, Prince of Eutin, and Albertina Frederica of Baden-Durlach.

Adolf Frederick died in Stockholm on 12 February 1771 after having consumed a meal consisting of lobster, caviar, sauerkraut, kippers and champagne, which was topped off with 14 servings of his favourite dessert: hetvägg made of semla and served in a bowl of hot milk.

The king was regarded, both during his time and in later times, as dependent on others, a weak ruler and lacking any talents. But he was allegedly also a good husband, a caring father, and a gentle master to his servants. His favourite pastime was to make snuffboxes, which he allegedly spent a great deal of time doing. His personal hospitality and friendliness were witnessed by many who deeply mourned him at his death.

Following his death, his son Gustav III seized power in 1772 in a military coup d'état, reinstating absolute rule.
