The trial of Anders Behring Breivik began in Oslo, Norway, focusing on his culpability for the horrific events of July 22, 2011, when he executed a well-coordinated attack that claimed the lives of 77 individuals, mostly teenagers at a Workers’ Youth League camp on the island of Utøya. He also detonated a bomb in Oslo that earlier that day killed eight people. Breivik, having confessed to the attacks, claimed he acted to defend Norway from multiculturalism and Islam, leading to a complex legal battle over his mental state and fitness for trial. The proceedings were attended by a large number of journalists and observers, turning the courtroom into a focal point for national and international discussions surrounding terrorism, radicalization, and the ethics of punishment.Throughout the trial, Breivik's defense team sought to argue that he was sane and, thus, responsible for his actions, while the prosecution aimed to depict him as a criminally insane individual, deeply affected by extremist ideologies. Testimonies from survivors highlighted the trauma inflicted on victims and their families, fostering a dialogue about trauma recovery, societal healing, and the role of government in preventing future attacks. As the trial progressed, the focus expanded to include a national reflection on values, security, and democratic resilience in the face of extremist violence.
