Despite its recent emergence or re-emergence in curricular around the world, ‘citizenship’ and therefore ‘citizenship education’ remain contested concepts. Each country or region accordingly may construct particular conceptions of citizenship and citizenship education. Therefore, it is often conceived around broad interpretations of citizenship based on historical changes in political, economic, social and cultural contexts. The main concern of this project is to explore how citizenship education and citizenship are related politically, and how national identity can be shaped and reshaped in a changing society with the tensions of nationalization, localization and globalization. It is hoped to illustrate the transformation of citizenship education by tracing back the history from Japanese colonization (1895-1945), post WWII (1945-1949), KMT authoritarianism (1949-1987), transitional period (1987-1996), to current period (1996- ). This paper mainly focuses on the period of Japanese colonization to examine the values and ideologies, such as colonization and nationalism, implied in the school system and citizenship education.
