constituted by objective and often physical characteristics like ancestry, skin color, or mother tongue, social constructive theories view ethnicity as a variable social category dependent on space and time. Two theories are of importance for the Turkish case: Nagel's (1994) social constructive model of ethnicity which underlines the influences and interrelations of the society, the state, individuals and groups in the social construction of ethnic categories, and Scott's (1990) argument that the perception of opposition on parts of a minority group leads to an increase in its ethnic identification. Based on these theoretical grounds, the empirical part examines the conceptions of Kurdish ethnicity in Turkey from the establishment of the Republic in 1923 until today. At first sight, the developments seem to have been oscillating non-systematically between the two poles of denial and recognition, and ended up in the contemporary paradox of an increasing recognition of Kurdish ethnicity facilitated by the politics of the contemporary AKP government on the one side, and growing social tensions on ethnic issues on the other side. But as the thesis argues, there are signs of a long-term process of increasing recognition of Kurdish ethnicity and growing interaction between parts of the society that define themselves and "Turkish" and "Kurdish". This development led to a stronger perception of opposition on the latter side, which in turn and according to Scott's theory strengthened their ethnic identification. The result of this process is the questioned paradox of recognition and conflict.
