Gustavus VI Adolphus (Oldenburg Sweden)

Gustavus VI Adolphus (Oscar Frederick William Olaf Gustavus Adolphus, Swedish: Oskar Fredrik Vilhelm Olof Gustav Adolf), born 11 November 1882 in Stockholm, died 15 September 1973 in Helsingborg, Sweden, became king of Sweden upon the death of his mother, Viktoria I, 4 April 1930.

He was the first regent of the house of Bernadotte. His father was a Swedish Count, Gustaf Bernadotte af Wisborg, who was a professional tennis player before marrying into the royal family. Count Gustaf's father (and King Gustavus VI Adolphus's paternal grandfather) was prime minister Count Oscar Bernadotte af Wisborg, himself a male-line grandson of general Jean Bernadotte, the first count Bernadotte af Wisborg.

Gustavus VI Adolphus was interested in archeology and mostly let his advisors and members of parliament handle the politics. Thus, Sweden turned into a more democratic country during his reign, a development that his successor, his grandson Charles XIV Gustavus successfully has reversed.

Gustavus VI Adolphus was married twice. He married princess Margaret (Margareta in Swedish) of Great Britain and Ireland in 1905, and they were married until she died in 1920. They had five children, among them prince Gustavus Adolphus, who was the present king's father. After Margaret's death, Gustavus Adolphus married another Brit: he and Lady Louise Mountbatten, were married in 1923, and stayed married until her death in 1965.
