The aim of this study is to empirically analyse the relationship of collective identity frames to the mobilisation strategies of the Czech Romani and pro-Romani activists over the past two decades. After all, most existing analyses merely implicitly assume that this relationship exists, and explain the relationship as the result of a given political opportunity structure, but they do not examine these frames more closely. Using frame and claim-making analysis, the text traces the diachronic and synchronic development of self-naming frames and the collective action repertoire in five-year intervals (1992, 1997, 2002, 2007, and 2012). It shows that, whereas self-naming significantly changes, the activists’ action repertoire does not. Thus, the frequently postulated relationship between self-naming, strategies and activists’ priorities is not confirmed. However, the analysis does reveal that certain claims and frames are connected with certain strategies and repertoire patterns. The paper concludes with a discussion of reasons for this diversification of activist framings, which may be the result of efforts to focus on different target audiences within the multiplicity of opportunity structures and a response to the (new) availability of external sources of funding in Central and Eastern Europe countries.
