The Islamic Revolutionary Guard Corps (IRGC) was formed shortly after the Islamic Revolution back in 1979, when US-backed Shah Mohammad Reza Pahlavi of Iran was overthrown. Soon the country became an Islamic Republic under the Grand Ayatollah Ruhollah Khomeini.
The Corps was created out of several paramilitary forces loyal to the new government - while the loyalty of the standing army was under question back then. The IRGC was tasked with protection of the gains of the Revolution itself, while the Army was entrusted with preserving the country's territorial integrity and independence.
However, the IRGC was soon forced to act as a regular army, following the Iraqi invasion in 1980. The IRGC had to substitute for dwindling numbers of the regular army, which had been plagued by desertions - and political purges - after the Revolution. Eventually, the IRGC grew its own aerospace (AFAGIR) and naval (NEDSA) forces, duplicating many of the responsibilities of Iran's regular military.
