From the late 19th century till the early 20^(th) century, Yeats, Synge, Lady Gregory and others drew on Irish folk tales and songs to add local color to their works. Though it was called the Gaelic Revival, the goal was to build Irish national consciousness. It worked. Ireland won independence from England in 1922. The success story of the Gaelic Revival in building a national identity of a colonized people through literary activities that culminated in political independence reached colonized lands in East Asia under Japanese rule, in particular Korea and Taiwan. The purpose of this paper is to shed light on how the Gaelic Revival helped build national consciousness in Taiwan. To this end, this study discusses two cases: First, Kikuchi Kan's adaptation of Lady Gregory's play to represent the Tapani Incident, which occurred in colonial Taiwan in 1915. Second, Liang Chi-chao's citation of the Irish experience to encourage Taiwanese people, such as the leader of Taiwan's "home rule" movement, Lin Hsien-tang, to create their own "Formosa experience" in print.
