Gustav V, King of Sweden (1858-1950), like most monarchs, was bisexual. http://www.glbtq.com/social-sciences/gustav_v.html
Gustav helped to keep Sweden neutral in the two world wars. He supported laws that included an eight-hour workday, child welfare, and subsidized low-income housing.
Gustaf was married to Victoria of Baden. They had three sons.
In the 1950s, after Gustav's death, there were several revelations about homosexuality among government officials.
A former restaurant owner, Kurt Haijby, revealed that he and King Gustav had been lovers from 1912 until 1932.
Haijby wrote a book about his relationship with King Gustav. Members of the court bought and destroyed every copy.
