This study focuses on the role of the interwar Romanian press in Transylvania in the creation of national identity following the union of the aforementioned province with the Kingdom of Romania in 1918. It argues that the Romanian press contributed significantly in constructing, circulating and reproducing a national identity buttressed by the discourse of integral nationalism during the first decade of the interwar period. Based on Romanian newspaper articles covering various nation-building policies and practices, this thesis examines the attempted nationalization of Transylvania's multi-ethnic, multi-confessional character through the politics of cultural engineering.
