In 2012, he co-founded the
Identitarian Movement of Austria, also referred to as "Generation Identity" in Austria, after discovering the French
Bloc Identitaire on the internet. Sellner copied their aesthetics, the black-yellow logo and the central term of "saving European identity". Contacts in right-wing
fraternities enabled him to convince sponsors of his new, right-wing radical youth group. By 2017 he had a bachelor in philosophy, and
die Zeit referred to him as graphic designer. along with around 30 members of his organisation, spilling fake blood. The blood was intended to symbolize the "blood of
Bataclan and
Brussels". In 2017, Sellner spoke at a
Pegida rally in
Dresden.
Legal and visa problems 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 early 2018 he had received a donation of $1,500 from the
Australian-born terrorist
Brenton Tarrant of the March 2019
Christchurch mosque shootings in
Christchurch,
New Zealand. In March 2018, Sellner and
Brittany Pettibone, at that time his girlfriend, 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 March 2019,
Austrian police searched his home; unusually, they waited 12 minutes for him to open the door. Sellner apparently had been warned and managed to delete all emails with Christchurch shooter Tarrant 40 minutes before the raid. His computer, mobile phone, all data storage devices and cash cards were confiscated on suspicion that he was a member of a terrorist organization. Sellner denied any involvement in the attacks. Also in March 2019, U.S. authorities canceled his permit to travel without a visa to the United States according to Sellner, thus preventing him from visiting Pettibone, now his wife. 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 and his fiancée could marry and live together in
Post Falls, Idaho, rather than his native Austria; following this, their marriage was instead held in Austria later that year. On 13 December 2019, a judge ruled that the searches were unlawful. Investigators had wrongly suspected Sellner of forming a terrorist organisation. According to the public prosecutor's office in
Graz, inspection of Sellner's bank account was illegal for a lack of
reasonable suspicion. In June 2019, Sellner was permanently excluded from entering the UK on security grounds in a letter sent to him by the
Home Office. A year earlier, Sellner had attempted to enter the UK via
Stansted airport, but had been stopped by the authorities. The Home Secretary,
Sajid Javid, feared that Sellner might try to enter the UK again to train the local branch of Generation Identity and carry out public stunts that would promote "anti-Islamic and anti-immigration narratives". In 2023, Sellner proposed a plan to "remigrate" millions of people from Germany to North Africa at the
2023 Potsdam far-right meeting. The meeting also hosted members of the
Alternative for Germany (AfD) party and the
Christian Democratic Union of Germany (CDU) party, leading to debate on banning the AfD. On 29 January 2024, Sellner entered Germany from Austria in a leased car. The police interrogated Sellner for nearly an hour before releasing him. On 19 March 2024, Sellner was banned from entering Germany for three years. According to German public media, Sellner had stated on his Twitter account that he would be "pushed back and punished" if he tried to enter Germany during the ban. The ban came after it was reported that Sellner had given a speech on "
remigration" to politicians from the
AfD and the
CDU in Potsdam on 25 November 2023. A court in Potsdam revoked the ban in late May 2024 on Sellner's application, declaring the original ban unlawful. On 16 March 2024, Sellner was arrested in
Switzerland while he was giving a speech at an event organized by the Swiss organization in
Tegerfelden. According to media reports, a senior police officer in Zurich had warned Sellner in a telephone call the day before that the intended event "must not take place". ==Political views==
