Islamic Revolutionary Guard Corps

The Islamic Revolutionary Guard Corps (IRGC) is a branch of Iran’s armed forces established after the 1979 Iranian Revolution.

Updated September 12, 20261 min readCited sources

The Islamic Revolutionary Guard Corps (IRGC) is a powerful branch of Iran’s military created after the 1979 revolution. It answers directly to the Supreme Leader and wields major influence in Iran’s security, politics, and economy.

What it is

Established in April 1979 by Ruhollah Khomeini, the IRGC was meant to protect the Islamic Republic’s new revolutionary system. It operates separately from Iran’s regular army and reports to the Supreme Leader, not the defence ministry.

Key components

The IRGC includes ground, naval, and aerospace forces, along with the Basij militia and the Quds Force for external operations. Its broad mandate covers defence, internal security, and covert activities.

Why it matters

The Guards have expanded into Iran’s economy and politics, becoming a target for international sanctions. The United States designated the entire corps a Foreign Terrorist Organization in 2019. For Canadian readers, the IRGC appears in discussions of sanctions and security policy.

In short

  • Created in 1979 to protect the Islamic Republic.
  • Operates outside Iran’s regular military chain of command.
  • Major role in politics, economy, and internal security.
  • Designated a terrorist organization by the United States and restricted by other governments.
Canadian angle

Canadian readers may encounter the IRGC in news about Iran, sanctions, security, and Canada’s designations of terrorist entities or related foreign policy measures.
