This article challenges two established views in the literature on Turkish nationalism. First, that Turkish nationhood in the early republican era was civic and ethnic and, second, that, while Turkish nationhood was inclusive and egalitarian in constitutional texts, in the early years of the Turkish Republic and in the case of Turkish citizens of Muslim origin, it became exclusive or discriminatory in citizenship practices once the Republic was consolidated and in the case of non-Muslim Turkish citizens. Contra these two established views, I first argue that Turkish nationhood was not civic and ethnic, but it was actually civic and ancestral and cultural. Secondly, relying on an examination of legal texts produced and citizenship practices pursued in the years between 1918 and 1924, I argue that the Turkish nationhood was exclusive and discriminatory both theoretically and practically, on paper as well as in practice, both at the time of the foundation of the republic and once the regime had become consolidated.
