This chapter discusses Alevis’ migration to Britain and their social mobilization to gain recognition in their new country. The England Alevi Cultural Centre and Cemevi (EACC) was initially founded in 1993 as an apolitical community center. Since 2008, with the change of the chairperson and administrative board, Alevi mobilization in Britain has embraced an inclusive membership policy and maintained softer boundaries with previously excluded groups, namely Kurds and leftist associations. By borrowing the conceptual tools from the literature on social movements, the chapter argues that the social and political opportunities and constraints at national, supranational, and transnational level and the framing of collective identity have facilitated the Alevi mobilization in recent years. The chapter shows that framing a unifying collective identity has been the most effective factor in the EACC’s success in mobilizing Alevis in Britain.
