Adolphus Frederick II (; 19 October 1658 – 12 May 1708), Duke of Mecklenburg, was the first Duke of the Mecklenburg-Strelitz, reigning from 1701 until his death. Mecklenburg-Strelitz was a part of the Holy Roman Empire.
Biography
He was born in Grabow as the posthumous son of Duke Adolf Frederick I of Mecklenburg and his second wife, Maria Katharina of Brunswick-Dannenberg (1616–1665).
In 1695, the Mecklenburg-Güstrow branch of the House of Mecklenburg became extinct and Adolphus Frederick's nephew, Frederick William, Duke of Mecklenburg-Schwerin, laid claim to the inheritance, a move which Adolphus Frederick opposed.
The dispute was settled in 1701 by dividing Mecklenburg-Güstrow between the two claimants. Frederick William took the Duchy of Mecklenburg-Schwerin, and Adolphus obtained the Principality of Ratzeburg and the Lordship of Stargard with the commanderies of Mirow and Nemerow, of which he formed the Duchy of Mecklenburg-Strelitz.
