There are two main aims of this dissertation: to present a legal and ideological history of the formation of the language regime in Turkey in the Republican period; and to analyze its transformation in the post-1980 era. A language regime is defined in this dissertation as a de jure or de facto regulation of the linguistic behavior, in its content or in its status, within a space of communicative action, such as that of a nation-state or a speech group. In other words, a language regime is a system of the governance of the linguistic domain within a defined political territory by planning and employment of particular policies. Language ideologies, on the other hand, are inseparable aspects of the formulation and operation of the language regimes. Such a conception of language enables an analysis of language as a domain of social and political power. In the first part of the dissertation, the history of the language politics in the Republican Turkey is analyzed through the concept of language regime, and the ideological repercussions pertaining to the designation and practicing of these regimes are assessed. The second part concentrates on the changes in post-1980s, within a globalizing environment, in the broadcasting policies and the ways in which language regimes have been transformed. Controversies over two basic processes have been analyzed in this part: the commercialization of the audio-visual domain, and the developments concerning broadcasting in minority languages
