It is disputed if the formal transfer of power from Field Marshal al-Bakr to Saddam Hussein on 07/16/1979 marked a shift from a military to a personalist regime (this is the coding of GWF). Before and after the Ba’th party remained the ruling party.11 However, since the formal rules were altered fundamentally from a non-electoral military regime reigned by a junta to a one-party regime it makes sense to identify a regime change on 07/16/1979 (Bengio 1998). The 1979 Ba’ath Party Purge, also known as the Comrades Massacre, was a significant event that marked Saddam Hussein’s consolidation of power into a personalist autocracy in Iraq. Orchestrated by Saddam Hussein, on 07/22/1979, six days after becoming president, this purge occurred and involved the execution of many Ba’ath Party members who were labeled as traitors in a dramatic and public display of power. The leading party members who were spared “were given weapons and directed to execute their comrades”.12 The executed leading members of the party were accused of taking part in a pro-Syrian plot to overthrow Hussein. Iraq subsequently cut off relations with its fellow Ba’athist regime in Syria, accusing Hafiz al-Assad of organizing the plot.12 This event was a crucial moment in solidifying Saddam’s personal control over Iraq. It served to eliminate potential rivals and instill fear among party members and the population, ensuring that loyalty to Saddam was paramount and unchallenged. From this point on, Saddam’s word was effectively law, and his personal authority was the primary force in Iraqi governance, characterizing his rule as a personalist autocracy. The ruling ideology since is described as Saddamist Ba’athism, a distinct form of Ba’athism.13 Starting from 1980, the party came under the control of the military and security services (Farouk-Sluglett/Sluglett 1987: 208-13, Brooker 1997: 115-118, Kamrava 1998: 73, Geddes/Wright/Frantz 2014b: 70-71). The events of July 1979 signify a regime change rather than a mere continuation of the existing regime. The transition involved a fundamental alteration of power structures, marked by a shift from collective leadership to personal dictatorship and the dismantling of previous checks on executive power. There was a purging of the Ba’ath Party, involving the elimination of influential party members who could challenge Saddam Hussein and transforming the party into a vehicle for his personal rule. The establishment of a personalist autocracy became evident through the creation of a cult of personality and the centralization of military and security forces under Saddam’s direct control. Additionally, an ideological shift occurred, moving from traditional Ba’athist ideology to Saddamist Ba’athism, with an emphasis on loyalty to Saddam over the party or state. According to LIED no multiparty executive and legislative elections were held in 1979, 1980 to 1994 only legislative elections, which weren’t multiparty, were held, from 1995 onward only multiparty executive elections were held. According to Polity5, during this period, the executive held unlimited authority with no institutionalized constraints on decision-making power. From 1980 to 2001, V-Dem’s JCE is interpreted by us as indicating that judicial constraints on the executive were limited, while V-Dem’s LCE is classified by us as indicating that legislative constraints on the executive were absent. For the year 2002, V-Dem’s JCE is interpreted by us as indicating that judicial constraints on the executive were limited, while V-Dem’s LCE is classified by us as indicating that legislative constraints on the executive were moderate. For 2003, V-Dem’s JCE and LCE are both interpreted by us as indicating moderate constraints on the executive. According to FH’s classification for the assessed regime period, a score between 11 and 14 makes the country not free, which we also place in the not free category. Moreover, the state of political liberties is indicated as absent according to LIED and V-Dem’s PCLI.
