The People's Mojahedin Organization of Iran (PMOI), also known as Mojahedin-e-Khalq (MEK) or Mojahedin-e-Khalq Organization, is an Iranian dissident organization. It was an armed group until 2003, afterwards switching focus into a political group. Its headquarters is currently in Albania. The group's ideology has been historically influenced by Islamic and revolutionary socialist philosophies, particularly through a re-interpretative approach to Shia Islam, shaped by the writings of Ali Shariati. After the Iranian Revolution, the MEK opposed the new theocratic Government of the Islamic Republic of Iran, seeking to replace it with its own government. At one point the MEK was Iran's "largest and most active armed dissident group", and it is still sometimes presented by Western political backers as a major Iranian opposition group. The MEK is known to be deeply unpopular today within Iran, largely due to its siding with Iraq in the Iran–Iraq War and continued ties with the government of Saddam Hussein afterwards.
