Anders Behring Breivik (born February 13, 1979, in Oslo, Norway) is a Norwegian neo-Nazi terrorist and mass murderer responsible for the 2011 Norway attacks. On July 22, 2011, he detonated a van bomb outside government buildings in Oslo, killing eight people, then attacked a Workers' Youth League (AUF) summer camp on the island of Utøya, where he killed 69 people, mostly teenagers, in a mass shooting, bringing the total death toll to 77. Breivik authored a 1,500-page manifesto titled '2083 – A European Declaration of Independence,' which outlined his far-right, anti-Islam, and cultural nationalist ideology, blaming multiculturalism and immigration for Europe's decline. He cited influences from anti-Islam bloggers and far-right thinkers, including Robert Spencer and Pamela Geller. Prior to the attacks, Breivik led an unremarkable life as a dropout who dabbled in business ventures, including selling fake diplomas online and working as a trader. He was radicalized online, adopting neo-Nazi views and self-styling as a 'Knights Templar' commander under aliases like Fjotolf Hansen and Far Skaldigrimmr Rauskjoldr av Northriki. In 2012, he was convicted of mass murder and terrorism, sentenced to 21 years in prison (Norway's maximum, with possibility of extension), and ruled sane by the court despite psychiatric evaluations suggesting paranoid schizophrenia. Breivik has since engaged in legal challenges against prison conditions, alleging human rights violations, and continues to express his ideology from incarceration. His actions have been widely condemned as a far-right terrorist attack targeting Norway's Labor Party and its youth wing for their pro-immigration policies. The attacks shocked the world, leading to national mourning and debates on extremism, security, and mental health. He remains imprisoned at Ringerike Prison, with ongoing controversies including his 2016 lawsuit against the state for isolation and a 2022 parole denial.
