"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.
The first king from the House of Holstein-Gottorp, Adolf Frederick was a weak monarch, instated as first in line of the throne following the parliamentary government´s failure to reconquer the Baltic provinces in 1741–43. Aside from a few attempts, supported by pro-absolutist factions among the nobility, to reclaim the absolute monarchy held by previous monarchs, he remained a mere constitutional figurehead until his death." - (en.wikipedia.org 04.06.2020)
