Martin Sellner

On 25 March 2019, Sellner's apartment was searched by the Austrian police. His computer, mobile phone, all data storage devices and cash cards were confiscated on suspicion that he was a member of a terrorist organization; early in 2018 he had received a donation of $1,500 from Brenton Harrison Tarrant, the Australian-born suspect in the Christchurch mosque shootings in Christchurch, New Zealand. Sellner denied any involvement in the attacks.

According to Sellner, U.S. authorities canceled his permit to travel without a visa to the United States thus preventing him from visiting his American fiancée Brittany Pettibone. In 2019, the Republican Committee of Pettibone's home county of Kootenai County, Idaho, called on the American federal government to allow Sellner to travel to the United States. The move caused considerable controversy within the Republican Party and the State of Idaho. Sellner has said he wants to be allowed into the country so he can marry his fiancée and so they can live together in Post Falls, Idaho, rather than his native Austria.

Austrian police expanded their searches of Sellners' property during June 2019 in connection with the Christchurch shootings. This search was later ruled illegal by a judge.

In June 2019, Sellner was permanently excluded from entering the UK on security grounds.

In March 2018, he was denied entry to, and deported from, the United Kingdom. A year later, he was denied entry to the United States.

In March 2018, Sellner and his girlfriend Brittany Pettibone were denied entry to the United Kingdom at Luton Airport on the grounds that their presence in the United Kingdom was not conducive to the public good. Sellner intended to deliver an address at Speakers' Corner in Hyde Park, London. They were denied entry, detained for two days and deported.

In February 2017, Sellner was involved in a fight in a Vienna U-Bahn station where he used pepper spray on people he described as far-left activists. Since this incident, he has been banned from carrying weapons.

In April 2016, he disrupted a theatre performance of Elfriede Jelinek's piece, Die Schutzbefohlenen (theatre performance with migrants seeking asylum), along with around 30 members of his organisation, spilling fake blood. The blood was intended to symbolize the "blood of Bataclan and Brussels".

ITV's documentary film investigation Undercover – The New British Far-Right claimed the existence of undercover footage of Sellner discussing contacts between Generation Identity and white supremacist groups in the United States, but stated that these contacts must be hidden due to public relations. The documentary claimed that Sellner stated that Jews were a problem in the 1920s and made references to the "Jewish question". Sellner also said that the domination of the American alt-right by the "Jewish question" is a "complete strategical and theoretical failure". It claimed he said he was an antisemite in his youth, and that his friends made offensive comments about the Holocaust. He supports The Great Replacement conspiracy theory. Sellner responded by calling the documentary a "hit piece", and that the statements were taken out of context. In a statement released by Generation Identity and Sellner, they stated that the group wants to preserve European "ethno-cultural identity" and stated that the group has no hidden agendas.

In 2008, he helped leading Austrian neo-Nazis hinder liberal demonstrations and made pilgrimages to memorial services for Wehrmacht soldiers.

In 2008, he helped a leading Austrian neo-Nazi group hinder liberal demonstrations and made pilgrimages to memorial services for Wehrmacht soldiers. In 2016, he said that he had broken with neo-Nazism, and that the rising popularity of Nazism is a failure of society.

Sellner was raised outside of Vienna. He became involved in nationalist politics as a teenager, being part of Austria's neo-Nazi scene. In 2006, at the age of 17, Sellner admitted placing a swastika on a synagogue in Baden bei Wien and was sentenced to 100 hours of community service in a Jewish cemetery. In 2016, Sellner was studying philosophy in Vienna. He dropped out of law school.

In 2006 he installed swastika stickers with another person on the synagogue in Baden, Lower Austria. Also stickers with a swastika and the inscription "Legalized It" as well as stickers with a coat of arms and the letters AJ (for "Aryan Youth") were used. The accomplice later stated in an interrogation that they had "wanted to do something" when they heard about the conviction of the British Holocaust denier David Irving. Sellner admitted the act and did 100 hours of community service in a diversion at the Jewish cemetery in Baden, which is why the public prosecutor's office renounced a criminal trial.

Martin Sellner (born 8 January 1989) is an Austrian Neue Rechte and Identitarian activist, and leader of the Identitäre Bewegung Österreichs (IBÖ, Identitarian Movement of Austria). He is active in the alt-right movement.
