Duke Adolf Friedrich II, Duke of Mecklenburg-Strelitz

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.

Following his death in 1708, Adolphus Frederick was succeeded as Duke by his son, Adolphus Frederick III.

Marriages and children In 1684 Adolphus Frederick II married firstly to Marie of Mecklenburg-Güstrow (19 July 1659 – 16 January 1701), daughter of Gustav Adolph, Duke of Mecklenburg-Güstrow. They had five children:

Adolphus Frederick III, Duke of Mecklenburg-Strelitz (Strelitz, 7 June 1686 – Schwerin, 11 December 1752).

Duchess Gustave Caroline of Mecklenburg-Strelitz (Strelitz, 12 July 1694 – Schwerin, 13 April 1748) she married Christian Ludwig II, Duke of Mecklenburg.

On 20 June 1702, Adolphus Frederick II married secondly to Princess Johanna of Saxe-Gotha (1 October 1680 – 9 July 1704), a daughter of Frederick I, Duke of Saxe-Gotha-Altenburg, and Magdalena Sybille of Saxe-Weissenfels, who was his half-niece. There were no children from this marriage.

On 10 June 1705 at Neustrelitz, Adolphus Frederick II married thirdly to Princess Christiane Emilie of Schwarzburg-Sondershausen (13 March 1681 – 1 November 1751), a daughter of Christian William I, Prince of Schwarzburg-Sondershausen and Countess Antonie Sybille of Barby-Mühlingen (1641–1684). They had two children:
