Frederick I of Sweden

Who was Frederick I of Sweden?

Frederick I, Swedish: Fredrik I, was a prince consort of Sweden from 1718 to 1720, and a King of Sweden from 1720 until his death and also Landgrave of Hesse-Kassel from 1730. He ascended the throne following the death of his brother-in-law, absolutist Charles XII in the Great Northern War, as his sister and heir Ulrika Eleonora preferred to abdicate from her position as queen regnant after relinquishing most powers to the Riksdag of the Estates. His powerless reign saw his family's elimination from the line of succession after the parliamentary government dominated by pro-revanchist Hat Party politicians ventured into a war with Russia, which ended in defeat and the Russian tsarina Elizabeth demanding Adolph Frederick of Holstein-Gottorp to be instated following the death of the king.
