This thesis attempts to grasp the complexity of the relationship between nationalism and media in multi-ethnic Latvia. Acknowledging the cultural diversity of Latvian society, the study draws upon Benedict Anderson’s notion of “imagined communities” to public service broadcasting, whereby adapting the national identity policy objectives is often conceived as a crucial tool in the construction of a nation. Considering language as the greatest cultural marker, it is inevitably a substantial part of identity politics and a nation-building instrument. While most research is devoted to countries dealing with officially recognized minority languages, this thesis investigates the approach of the Latvian public broadcasters, Latvian Television and Radio Latvia, to a large ethnic minority population with an unrecognized (legally) Russian language. By means of a methodological triangulation, this interdisciplinary study aims to contribute primarily to media and minority fields of research. In light of the empirical findings, it is argued that there is a significant gap between the legislative framework and the programme output in public service broadcasting in Latvia. It is proposed that the ambiguous relationship between public media and nationalism must be understood through cultural, historical and socio-political perspectives.
