In this article, our coding unit is a government ban on protests. Our dataset covers bans from January 2007 to December 2019. As indicated above, we used two newspapers, Hürriyet, a national mainstream paper, and Bianet, a national oppositional internet-based newspaper, and searched for government bans, cross-checking the two papers against each other. To find government bans, our research assistants went through the online archives of these newspapers manually, looking for government bans and protest news for every single day for the aforementioned period. They coded the relevant information in an excel table according to our codebook, which entails 28 variables. We then went over each entry to check if the coding is correct, eliminated and corrected when necessary.Throughout data collection and coding, we have worked with seven research assistants in total, a mix of senior undergraduates and graduate students, in different time periods. All students received training from us and went through a trial phase when we went over their coding together. The initial phase of the coding began in June 2017 and finished in August 2017. A second phase took place in January-February 2018. Since then we worked with a regular research assistant, who have both reviewed past work and coded the remaining period.In our dataset, we recorded only those cases where there is a declaration by a public authority (governor, district heads, rectors, public prosecutors) banning a protest or declaring a protest illegal. In many cases a ban would be officially announced and newspapers will report this official announcement. Sometimes, however, we did not find the official announcement but communication by various authorities who spoke of the protest in question as banned or as illegal. We included these cases in our data-set. These authorities are mostly governors and district heads (kaymakam) but chief prosecutors in the case of courts and rectors in the case of universities also ban protests within their jurisdiction.Mistakes in coding generally involved coding police intervention as a protest ban, even when there is no prior ban. We have excluded cases of de-facto police intervention when there is no prior decision that bans the protest. Police intervention and violence against protests and protestors regularly occur in Turkey even when a protest is not banned/not permitted beforehand. Police may intervene in a protest if there is no prior notification, the procedures specified in the Law 2911 were not exactly followed, or protestors make statements, carry symbols, engage in actions deemed illegal. Violence against protestors also occurs in the absence of any of those things. Therefore, we consider protest bans issued by authorities and police interventions as distinct but not mutually exclusive modalities of protest control.
