Political factions in Iran
Politics in Iran are dictated by factionalism. Post-1979. 1990s. Behrouz (1991). Maziar Behrooz wrote in 1991 that by 1989, there are three identical factions in Iran, namely the Conservatives, the Reformists (radical-reformists) and the Pragmatists (pragmatic-reformists). Behrooz states that the reformists were statist, while the conservatives were pro-private sector. Behrooz states that the two reformist factions (radicals and pragmatists) were united in opposition to the conservatives and over domestic issues. In this classification, the pragmatists were headed by figures such as Akbar Hashemi Rafsanjani, and differed with the radicals (represented by Mir-Hossein  Mousavi among others) mainly over foreign relations. While the pragmatists believed in establishing friendly relations with both the West and the East, as well as post-war reconstruction under state control and foreign investment, the radical reformists tended towards an isolationist strategy in foreign policy and rejected the foreign investment. The reformists who won the parliamentary elections in 1988 were represented by the Association of Combatant Clerics which split off from the conservative Combatant Clergy Association. He cited two additional developed and "semi-legal" factions outside power, the first of which is represented by the Freedom Movement of Iran and  some of Mehdi Bazargan's allies from the National Front. The second faction is "the movement shaped around some top Grand Ayatollahs" who opposed the theory of "Velayat Faqih", such as Ahmad Azari Qomi. Nabavi (1994–95). With an article entitled "The political tendencies within Iran today", Behzad Nabavi of the Mojahedin of the Islamic Revolution of Iran Organization (MIRIO) started a series of pieces, published between November 1994 and May 1995 in the bi-weekly "Asr-e Maa", to distinguish four political factions in Iran which he characterizes as "Traditional Right", "Modern Right", "New Left" and "Left". These factions are  characterised as follows: The first conceptualization of its kind after the Iranian revolution, it turned out accepted by many in Iran. According to Mehdi Moslem, the classifaction was considered "the most accurate and comprehensive picture of the ideological differences within the Iranian polity" but several others dispute accuracy of this analysis. Critics point out that the conflict of interest has undermined the usefulness of it, as Nabavi himself was involved in the political grouping that he presented as stable, united and towards voctory ("Left"). Mohammad Ghouchani, for example, except for the latter criticism, comments that the classification fails to acknowledge  the groups that lay beyond its boundaries, not recognizing the exceptions and thus not fully reflecting the variety and fluidity of the political players and their economic outlooks. Alireza Alavitabar is against accuracy of the categorisation, due to the labels chosen and neglecting the faction he refers to as "Modern Left", (represented by the IIPF) because of what he deems "their [MIRIO's] own strategic interests". Based on this classification, Wilfried Buchta writes in 2000 that the 'New Left' "has played a very minor role" and whether it is "an independent ideological faction... cannot be determined". He compares the  other three factions as follows: Baktiari (1996). Bahman Baktiari, Director of the School of Policy and International Affairs at the University of Maine, states that the Parliament ("Majles") continued to play a significant role in the post-revolutionary Iran from May 1980 and has also been the center of elite factionalism and power rivalry. Following the defeat of the Radicals in the 1992 elections, President Rafsanjani and his supporters move to consolidate their influence in other institutions such as the Judiciary and Office of the Supreme Leader. Baktiari claimed that Ayatollah Khomeini's leadership style did not allow one faction  to gain the upper hand in its effort to eliminate the rival faction, therefore and as the balancer, Khomeini perceived the Parliament as a useful arena for factions to debate their conflicting viewpoints. He provides that the term of "correntocrazia" (translated "factionocracy") can be aptly applied to the political system of Iran. Post-2000s. Warnaar (2013). Maaike Warnaar, Assistant Professor of the International Relations and Politics of Iran and the Middle East in the Leiden University, states that the Iran's power structure is characterized by loose coalitions consist of people loyal to the idea of an Islamic state, but views  on what this Islamic state should entail diverge. She provides a table based on the Iran's factions under Presidency of Ahmadinejad (2005–13) as follows: Warnaar noted that these categories by definition overlap because Iranian politics is centered on individuals rather than political factions and allegiances may shift depending on the topic, issue, or other circumstances. Mohseni (2016). Payam Mohseni, fellow at the Belfer Center for Science and International Affairs, provides an analysis based on the theocratic–republican divide (unique to the Islamic Republic of Iran) and the typical economic left–right dualism, classifying four political positions: the theocratic right , the republican right, the theocratic left, and the republican left. He names the main groups and figures of each faction as follows: According to Mohseni, theocrats believe the primary source of legitimacy for the Iranian government is "Velayat Faqih", which they deem "divinely ordained", while the republicans think "the ultimate authority rests squarely with the people". Moreover, the rights are capitalist and favor free market, maintaining ties to the "Bazaari" class and prioritizing economic growth over social justice. The left theocrats are anticapitalist, advocate state intervention in the economy and promote social justice and equal welfare. However, the republican lefts  who once were revolutionary anticapitalist, had an "ideological change" and largely shifted right to become more aligned with liberal economics. He additionally cites a recent defection within the theocratic right toward the republican right (demonstrated by individuals such as Ali Motahari) and the split of theocratic left into two different yet overlapping groups of pro-Ahmadinejad and pro-Mesbah. The main alliances shaped between the factions mentioned as follows: Mohseni states that those commonly refer to themselves as the 'Principlists', are members the alliance of theocrats (left and right) and the 'Reformists' are the republicans (left and right). Alternative classifications . Marc Champion, wrote an op-ed published in the "Bloomberg News" in 2016, suggesting that instead of two "neat camps" there are four "messy camps" in Iran: 'principlists', 'pragmatic principlists', 'radical republicans' and 'pragmatic reformers'.
