Frederick IV of Denmark Oldenburg 1
General Notes: In 1700 Frederick allied himself with Russia and Poland in the Great Northern War against Sweden, but he was soon compelled by Charles XII, king of Sweden, to withdraw from the conflict and to promise not to reenter it. After the defeat of Charles at Poltava (now in Ukraine) in 1709, however, Frederick again declared war on Sweden, subsequently taking the German duchy of Schleswig and participating with the Poles in the invasion of the Swedish portion of Pomerania. By treaty in 1720 Frederick agreed to return to Sweden all conquests made in the war, except for Schleswig. Among the accomplishments of his reign was the freeing of the peasants from serfdom in 1702. Noted events in his life were: • Acceded: 1699. King of Denmark and Norway. Frederick married Louise Mecklenburg-Güstrow, daughter of Gustav Adolf von Mecklenburg-Güstrow and Magdalene Sibylle von Holstein-Gottorp, on 5 Dec 1695. (Louise Mecklenburg-Güstrow was born on 28 Aug 1667 and died on 15 Mar 1721.) Frederick next married Anna Sophie von Reventlow on 4 Apr 1721. |
