Through Auxiliaries

The IRGC was officially established by Ruhollah Khomeini as a military branch in May 1979 in the aftermath of the Iranian Revolution. Whereas the Iranian Army (the Artesh) protects the country's sovereignty in a traditional capacity, the IRGC's constitutional mandate is to ensure the integrity of the Islamic Republic. Most interpretations of this mandate assert that it entrusts the IRGC with preventing foreign interference in Iran, thwarting coups by the traditional military, and crushing "deviant movements" that harm the ideological legacy of the Islamic Revolution.

The IRGC has approximately 125,000 personnel, as of 2024. The main body is the IRGC Ground Forces, which focus on maintaining internal order, but have recently moved towards expeditionary warfare also, projecting power for the Islamic Republic. The IRGC Navy is now Iran's primary force exercising operational control over the Persian Gulf, serving as a de facto coast guard. The IRGC Aerospace Force is responsible for the Iranian ballistic missile program and act as the country's space force. The Basij, a paramilitary volunteer militia that serves as the IRGC's auxiliaries, has a further approximately 90,000 active personnel. Lastly, the Quds Force is a unit specialized in unconventional warfare, military intelligence and clandestine operations, responsible for arming, training, advising and, in some cases, commanding pro-Iranian non-state actors abroad—such as Hezbollah and the Houthis. It operates a media arm, known as "Sepah News" within Iran. Currently, the IRGC is designated as a terrorist organization by Albania, Argentina, Australia, Bahrain, Bosnia and Herzegovina, Canada, Colombia, Costa Rica, the Dominican Republic, Ecuador, the European Union, Honduras, Iceland, Israel, Liechtenstein, Moldova, Montenegro, North Macedonia, Paraguay, Saudi Arabia, Serbia, Sweden, Trinidad and Tobago, Ukraine, and the United States.

Originating as a radical ideological militia, the IRGC has taken on a growing role in nearly every aspect of Iranian politics, economics (including energy and food industries) and society. In 2010, BBC News described the organization as a "business empire". In 2019, Reuters described it as "an industrial empire with political clout". IRGC's expanded social, political, military, and economic role under Mahmoud Ahmadinejad—especially during the 2009 presidential election and the suppression of post-election protests—has led many Western analysts to argue that it has surpassed even the country's ruling clerical class in terms of political power. In 2026, Reuters described the IRGC as a "state-within-a-state".

Terminology

Government organizations in Iran are commonly known by one-word names that denote their function, rather than acronyms or shortened versions. The general public refers to the IRGC as Sepâh (سپاه; Sepoy; Sipahi). Sepâh has a historical connotation of soldiers, while in modern Persian it also describes a corps-sized unit. In modern Persian, Artesh (ارتش) is the more standard term for an army.

Pâsdârân (پاسداران) is the plural form of Pâsdâr (پاسدار), meaning "Guardian", and members of Sepah are known as Pāsdār, which is also their title and comes after their rank.

Apart from the name Islamic Revolutionary Guard Corps, the Iranian Government, media, and those who identify with the organization generally use Sepāh-e Pâsdârân (Army of the Guardians), although it is not uncommon to hear Pâsdârân-e Enghelâb (پاسداران انقلاب; Guardians of the Revolution), or simply Pâsdârân (پاسداران; Guardians) as well. Among the Iranian population, and especially among diaspora Iranians, using the word Pasdaran indicates hatred or admiration for the organization.

Most foreign governments and the English-speaking mass media tend to use the term Iranian Revolutionary Guards (IRG) or simply the Revolutionary Guards. In the US media, the force is frequently referred to interchangeably as the Iranian Revolutionary Guard Corps or the Islamic Revolutionary Guard Corps (IRGC). The US government standard is Islamic Revolutionary Guard Corps, while the United Nations uses Iranian Revolutionary Guard Corps.

In the emblem of the Islamic Revolutionary Guard Corps, the sentence above the weapon consists of a segment of the Quranic verse from Surah Al-Anfal —وَأَعِدُّوا لَهُمْ مَا اسْتَطَعْتُمْ مِنْ قُوَّةٍ—which, according to the translation by Abdullah Yusuf Ali, reads: "Against them make ready your strength to the utmost of your power."
