About Beatrix of the Netherlands
Beatrix (Beatrix Wilhelmina Armgard, Dutch pronunciation: [ˈbeːjaːtrɪks ˌʋɪlɦɛlˈminaː ˈʔɑr(ə)mɡɑrt]; born 31 January 1938) is a member of the Dutch royal house who reigned as Queen of the Netherlands from 30 April 1980 until her abdication in 2013. Beatrix was born during the reign of her maternal grandmother, Queen Wilhelmina, and became heiress presumptive upon the accession of her mother, Queen Juliana, in 1948. Beatrix attended a public primary school in Canada during World War II, and then finished her primary and secondary education in the Netherlands in the post-war period. In 1961, she received her law degree from Leiden University. In 1966, Beatrix married Claus von Amsberg, a German diplomat, with whom she had three children. When her mother abdicated on 30 April 1980, Beatrix succeeded her as queen. Beatrix's reign saw the country's Caribbean territories reshaped with Aruba's secession and becoming its own constituent country within the kingdom in 1986. This was followed by the dissolution of the Netherlands Antilles in 2010, which created the new special municipalities of Bonaire, Sint Eustatius, and Saba, and the two new constituent countries of Curaçao and Sint Maarten. On Koninginnedag (Queensday), 30 April 2013, Beatrix abdicated in favour of her eldest son, Willem-Alexander, who became the first male monarch of the Netherlands since the death of William III in 1890. At the time of her abdication at age 75, Beatrix was the oldest reigning monarch in the country's history. Beatrix's middle names are the first names of her grandmothers, Queen Wilhelmina of the Netherlands and Armgard, Princess of Lippe-Biesterfeld.
