Ingroup, outgroup, or ally? An inquiry on the identity content of the People’s Protection Units (YPG) supporters on social media

Since the Syrian civil war broke out in 2011, the People’s Protection Units (Yekîneyên Parastina Gel?, the YPG) has been one of the most notable groups in Syria. The group has become increasingly known especially after playing a significant role in the fight against the Islamic State in Iraq and Syria and, later on, declaring autonomy in northern Syria in 2014. While various political, economic, and social dimensions of the Rojava struggle and of the YPG have been examined within a wide array of fields, the group and its identity have not been adequately examined through a social-psychological lens thus far. In this study, we seek to fill this gap by examining how YPG supporters represent, understand, and express the identity and behaviour of their own group and their adversaries on social media, particularly on Twitter. In light of social identity theory, we explore YPG supporters’ (1) ingroup representations (both ingroup members and allies), (2) ingroup social norms, (3) outgroup representations, and (4) outgroup social norms. Thus, we not only present the first empirical study in this regard, but also discuss the meanings of identity content and social norms in relation to the processes of mobilization and solidarity among YPG supporters.
