Frederick I (Swedish: Fredrik I; 28 April 1676 – 5 April 1751) was prince consort of Sweden from 1718 to 1720, and King of Sweden from 1720 until his death and (as Frederick I) 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, and the abdication of his wife, Charles's sister and successor Ulrika Eleonora, after she had to relinquish most powers to the Riksdag of the Estates and thus chose to abdicate.
His powerless reign and lack of legitimate heirs of his own 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 getting Adolph Frederick of Holstein-Gottorp instated following the death of the king.
