The Basij, officially known as the "Organization for the Mobilization of the Oppressed", is a volunteer paramilitary organization in Iran subordinate to the Islamic Revolutionary Guard Corps (IRGC).
It is considered one of the IRGC’s principal arms and claims the ability to mobilize hundreds of thousands of volunteers. Alongside its military functions, it operates in many areas of Iranian society, including ideological education, political activity, social control, educational institutions, and the economy.
The Basij emerged during the 1979 Islamic Revolution, and its importance grew considerably during the Iran–Iraq War of 1980–1988, when large numbers of volunteers were mobilized for military service. Basij units fought alongside the regular armed forces and the IRGC and took part in major operations. During Operation Fath ol-Mobin in March 1982, for example, its units participated in large-scale infantry assaults against Iraqi defensive positions.
Over the course of the war, the organization became an important source of manpower for the Islamic Republic.
After the war, the Basij became more deeply integrated into the structure of the IRGC, and in 2007 it was placed directly under its command. At the same time, its presence in Iranian society expanded far beyond the conventional military sphere. The organization is active in schools and universities, propaganda and ideological education, religious supervision and surveillance, as well as political and economic activities. It also takes part in public works projects and disaster-relief operations, including rescue and assistance efforts following severe flooding in western Iran in 2019.
The Basij’s decentralized structure provides the Iranian government with an extensive network of activists and volunteers identified with the values of the revolution and active across different sectors. As a result, it serves a combined role as a military auxiliary force, a political and social organization, a security body, and an ideological institution.
Its direct connection to the IRGC distinguishes it from civilian organizations, while its activities in educational and social institutions give it a role far broader than that of a conventional reserve force.
Over the years, the Basij has played a significant role in suppressing political protests. Human rights organizations have documented the use of violence by Basij members and other security forces against protesters and opposition activists. Testimonies have described Basij members moving in groups on motorcycles, beating and even killing protesters.
Basij personnel were also among those accused of human rights violations during the 2022 "Woman, Life, Freedom" protests, which erupted following the death of Mahsa Amini after her arrest by the morality police. Amnesty International reported testimonies of sexual violence committed by members of the IRGC, the Basij, the Ministry of Intelligence, and various police forces.
The organization also appeared in reports on the suppression of the nationwide protests that began in December 2025, when Basij battalions were among the security forces involved in the deadly crackdown on the demonstrations.
The Basij also has significant economic activities. The "Basij Cooperative Foundation (Bonyad Taavon Basij)" has been identified by the U.S. Department of the Treasury as an economic arm linked to the organization. In October 2018, the United States imposed sanctions on the foundation and on a network of companies and financial institutions used to conceal Basij ownership or control of assets in sectors including the automotive industry, mining, metals, and banking.
