The Terrorgram Collective: International Terrorists Promoting Violence and White Supremacy

On January 13, 2025, the United States Department of State designated the Terrorgram Collective and three of its foreign leaders as Specially Designated Global Terrorists (SDGTs), formally including Terrorgram among other international terrorist groups.  

Terrorgram is a decentralized network of white supremacist, neo-Nazi and accelerationist groups and individuals connected primarily through the encrypted social networking app Telegram, with the collective goal of promoting stochastic terrorism and inspiring individuals to conduct either group-oriented or “lone wolf” terror attacks. The network first began to take shape in 2019 and 2020, in the wake of Australian white supremacist Brenton Tarrant’s deadly terror attacks at two mosques in Christchurch, New Zealand. Terrorgram members seek to convince more white supremacists to conduct similar violent attacks in service of their accelerationist ideology. 

Key Facts to Know:  

The white supremacist ideology behind Terrorgram promotes violent actions and sabotage to achieve goals.

• Accelerationism, the main ideology promoted by Terrorgram, is a belief system within some segments of the white supremacist movement that promotes violent actions and sabotage as means to accelerate a perceived inevitable collapse of society, allowing followers to establish a white ethno-state in the aftermath. Since its emergence and spread in the late 2010s, white supremacist accelerationism has inspired multiple terrorist plots and attacks in countries around the world.  Adherents of the ideology generate propaganda, shared primarily online, that venerates past far-right killers—often referring to them as “saints”—and encourages people to emulate them, suggesting that they too would be remembered as saints after committing their violent acts.

Terrorgram propaganda is designed to inspire readers to commit extreme violence against marginalized groups.  

• The Terrorgram Collective is an inner circle of Terrorgram propagandists, who create and disseminate zine-style digital publications called the Terrorgram Publications, which contain instructional manuals and creative works of fiction with distinctive layouts and design. They are designed to inspire readers to commit acts of extreme violence against people and acts of sabotage and destruction against critical infrastructure targets. The publications frequently demonize Jews, Muslims, people of color, immigrants, and the LGTBQ+ community, and particularly glorify acts of violence, such as mass shootings, committed against these communities.  

Terrorgram Collective and their publications have directly inspired multiple terror acts and plots in the U.S. and abroad.

• The Terrorgram Collective and their publications have directly inspired multiple recent terror attacks and plots both in the United States as well as abroad, including a shooting outside an LGBTQ+ bar in Bratislava, Slovakia, in 2022; a mass stabbing attack at a mosque in Eskişehir, Turkey, in 2024; and an alleged plot to destroy an energy facility in East Brunswick, New Jersey, in 2024.

U.S. authorities designated the Terrorgram Collective and its leaders as Specially Designated Global Terrorists (SDGTs).

• On September 5, 2024, federal authorities arrested Matthew Allison of Boise, Idaho, and Dallas Humber of Elk Grove, California, for their alleged leadership roles in the Terrorgram Collective, charging them with soliciting hate crimes, soliciting the murder of federal officials, and conspiring to provide material support to terrorists.  When the U.S. Department of State designated the Terrorgram Collective as SDGTs in January 2025, they specifically designated three of their foreign leaders—Ciro Daniel Amorim Ferreira of Brazil, Noah Licul of Croatia, and Hendrik-Wahl Muller of South Africa--as SDGTs, as well.
