The article deals with the transformation of the Crimean Tatars’ institutions and discourses after the 2014 conflict around Crimea. It shows the change in the balance of power of traditional institutions such as Mejlis and Muftiyat, which for many years represented secular and religious components of Crimean Tatars’ ethnic identity. It tells how the Mejlis was dismissed from the political stage in Crimea, while the Muftiyat has enjoyed a great support by new authorities. This transformation and threats to societal security inevitably led to reassessment of previous views and goals of the main actors in the Crimean Tatar community and the formation of new institutions with hybrid composition and discourse. The article focuses on organization such as ‘Crimean solidarity,’ which was formed in 2016 as a reaction to authorities’ pressure over the Crimean Tatars. Using discourse analysis of statements of activists of this organization and content analysis of social media, the author presents the main topics of its discourse and types of activity. She shows how the traditional Islamic discourse of activists of this organization has been transformed by the incorporation of the main concepts of secular discourse developed by the Mejlis. The author argues that the appearance of ‘Crimean solidarity’ indicates the blurring of lines between secular and religious, and ethnic and Islamic in the Crimean Tatar society. It shows how people with different backgrounds and agendas manage to leave their differences aside to support each other in the face of a common threat.
