Political Undesirables considers the legal making and unmaking of citizenship in Iraq, focusing on the mass denaturalization and deportation of Iraqi Jews in 1950-51 and Iraqis of Iranian origin in the early 1980s. Since the formation of the modern state of Iraq under British rule in 1921, practices of denaturalization and expulsion of citizens have been mobilized by ruling elites to curb political opposition. Iraqi politicians, under both monarchical and republican rule, routinely employed the rhetoric of threats to national security, treason, and foreignness to uproot citizens they deemed politically undesirable. Using archival documents, ethnographic research, and literary and autobiographical works, Zainab Saleh shows how citizenship laws can serve as a mechanism to discipline the population. As she argues, these laws enforce commitment to the state's political order and normative values, and eliminate dissenting citizens through charges of betrayal of the homeland. Citizenship in Iraq, thus, has functioned as a privilege closely linked to loyalty to the state, rather than as a right enjoyed unconditionally. With the rise of nativism, right-wing nationalism, and authoritarianism all over the world, this book offers a timely examination of how citizenship can become a tool to silence opposition and produce precarity through denaturalization.
