Who married Duke Henry of Mecklenburg-Schwerin?

Duke Henry of Mecklenburg-Schwerin (German: Heinrich Wladimir Albrecht Ernst; Dutch: Hendrik Vladimir Albrecht Ernst; 19 April 1876 – 3 July 1934) was Prince of the Netherlands from 7 February 1901 until his death in 1934 as the husband of Queen Wilhelmina. He remains the longest-serving Dutch consort.

Wilhelmina (Dutch pronunciation: [ʋɪlɦɛlˈminaː] ; Wilhelmina Helena Pauline Maria; 31 August 1880 – 28 November 1962) was Queen of the Netherlands from 1890 until her abdication in 1948. She reigned for nearly 58 years, making her the longest-reigning monarch in Dutch history, as well as the longest-reigning female monarch outside of the United Kingdom. Her reign encompassed World War I, the Dutch economic crisis of 1933 and World War II.

The only surviving child of King William III of the Netherlands and Emma of Waldeck and Pyrmont, Wilhelmina ascended the throne at the age of 10 after her father's death in 1890, under her mother's regency. After taking charge of government, Wilhelmina became generally popular for maintaining Dutch neutrality during the First World War and solving many of her country's industrial problems. By that time, her business ventures had made her the world's first female billionaire as measured by U.S. dollars.

Following the German invasion of the Netherlands in 1940, Wilhelmina fled to Britain and took charge of the Dutch government-in-exile. She frequently spoke to the nation over radio and came to be regarded as a symbol of the Dutch resistance. By 1948, she had returned to the liberated Netherlands and was the only survivor of the 17 European monarchs who were reigning at the time of her inauguration. Increasingly beset by poor health, Wilhelmina abdicated in favour of her daughter Juliana in September 1948 and retired to Het Loo Palace, where she died in 1962.

Largely due to her status as a symbol of the Resistance, she remains reasonably popular in the Netherlands, even among the Dutch Republican movement.
