Islamic Republican Party
The Islamic Republican Party (Persian: حزب جمهوری اسلامی, Ḥezb-e Jomhuri-ye Eslāmi; IRP) was a clerical political organization in Iran established in May-June 1979 by five prominent Shiʿite clerics aligned with Ayatollah Ruhollah Khomeini to consolidate revolutionary gains and implement an Islamic theocratic governance structure.[1] As the dominant force in post-revolutionary politics, the IRP mobilized support for Khomeini's doctrine of velayat-e faqih (guardianship of the jurist), dominating the 1980 parliamentary elections with over 70% of seats and playing a central role in drafting the 1979 Constitution that enshrined clerical supremacy.[2] The party rapidly expanded its influence through grassroots networks in mosques and bazaars, effectively sidelining liberal, nationalist, and leftist factions that had initially allied with revolutionaries against the monarchy.[3] Key leaders such as Ayatollah Mohammad Beheshti, who headed the judiciary, and future Supreme Leader Ali Khamenei steered the IRP toward right-wing fundamentalist policies, emphasizing strict Islamic law enforcement and export of revolution.[2] Its achievements included institutionalizing the Islamic Republic's core apparatuses, such as the Revolutionary Guards and Guardian Council, which ensured ideological purity in governance.[4] However, the IRP faced severe internal divisions between hardline fundamentalists and more pragmatic or leftist-leaning Islamists, exacerbated by events like the 1981 bombings that killed dozens of its leaders, including Beheshti.[5] Controversies arose from its role in suppressing dissent, including executions of political rivals and purges within revolutionary circles, which critics attribute to authoritarian consolidation rather than mere defense against counter-revolutionaries.[6] Factional strife ultimately prompted Khomeini to order the party's dissolution in June 1987, as it had become a liability hindering unified regime control.[5][3] Despite its short lifespan, the IRP's legacy endures in Iran's enduring clerical dominance and the absence of competitive multipartism.[4]
