Background: Julian Paul Assange (; ne Hawkins; born 3 July 1971) is an Australian computer programmer and the editor of WikiLeaks. Assange founded WikiLeaks in 2006, but came to international attention in 2010, when WikiLeaks published a series of leaks provided by Chelsea Manning. These leaks included the Collateral Murder video (April 2010), the Afghanistan war logs (July 2010), the Iraq war logs (October 2010), and CableGate (November 2010). Following the 2010 leaks, the federal government of the United States launched a criminal investigation into WikiLeaks and asked allied nations for assistance.
Context: Assange was born in Townsville, Queensland, to Christine Ann Hawkins (b. 1951), a visual artist, and John Shipton, an anti-war activist and builder. The couple had separated before Assange was born.  When he was a year old, his mother married Richard Brett Assange, an actor, with whom she ran a small theatre company. They divorced around 1979. Christine Assange then became involved with Leif Meynell, also known as Leif Hamilton, a member of Australian cult The Family, with whom she had a son before the couple broke up in 1982. Assange had a nomadic childhood, and had lived in over thirty Australian towns by the time he reached his mid-teens, when he settled with his mother and half-brother in Melbourne, Victoria.  He attended many schools, including Goolmangar Primary School in New South Wales (1979-1983) and Townsville State High School, as well as being schooled at home. He studied programming, mathematics, and physics at Central Queensland University (1994) and the University of Melbourne (2003-2006), but did not complete a degree.  While in his teens, Assange married a woman named Teresa, and in 1989 they had a son, Daniel Assange, now a software designer. The couple separated and initially disputed custody of their child. Assange was Daniel's primary caregiver for much of his childhood. In an open letter to French President Francois Hollande, Assange stated his youngest child lives in France with his mother. He also said that his family had faced death threats and harassment because of his work, forcing them to change identities and reduce contact with him.
