What cultural issues do incentivize conservative mobilization? Issue-oriented conservative movements run the range from the anti-abortion movement in America to the most recent anti-globalization movements across the World. With the end of the Iran-Iraq War (1980-1988), the post-war transitional period started in Iran. Islamist conservatives, who self-identified as revolutionary principlists, understood some of the post-war cultural changes as threats to ideological cores of the 1979 Islamic revolution. One of the most mobilizing cultural issues for principlists after the war was "bad-hijabi" (improper hijab). “Bad-hijabi,” to revolutionary principlists, was the most disturbing cultural issue in the early years after the war. Drawing on Risalat, one of the most widely-read principlists’ newspapers since end of the 1980s, I discuss how principlists mobilized around “bad-hijabi.” I have looked at all issues of Risalat in early years after the war. I have not sampled on specific days or weeks. I have read and analyzed pertinent reports, comments, and op-eds from 1988 (the end of the war) till 1992. I have coded comments, papers and reports to analyze principlists’ language and understanding of "bad-hijabi." I have also looked at various events driven by principlists' outrage in Tehran and other parts of the country. These events include routinized events (for example, Friday prayer sermons), as well as non-routinized events such as disruptive demonstrations and meetings during weekdays. I argue that the “culture war” against “bad-hijabi” was the beginning of principlists’ long campaign against perceived liberal and secular threats in the country, which reached its peak during the Reform Era (1997-2005). I suggest that “bad-hijabi” shaped principlists’ immediate perceptions of liberal cultural threats in post-war Iran. Building on the “culture war” argument and through examining the Iranian brand of “culture war,” this study contributes to issue-oriented social movements, especially conservative movements in the context of Iran.
