Globalization has been remaking the world order in terms of world economy, cosmopolitan culture and international social movements. Through globalization, we could enjoy many cultures and communicate between us without any obstacle. On the other hand, it was thought to be the extension of modernization, bringing about many problems. In connection with the expansion of globalization, Samuel Huntington's theory of ' The Clash of Civilizations' is worth mentioning. According to him, the 21th century as de-cold period, is faced with the collision of cultures based on religions. As far as globalization is considered to be the expansion of American culture, the world- wide resistance is already predicted. Especially the countries which had gone through colonization are seeking their own alternatives to the global culture. In connection with this, modern Irish poets are the representatives who are moving toward the ideal glocalism. What I mean by ideal glocalism includes making definition of localism, the appropriation of global power, objectifying the local culture and seeking for the new humanism. The modern Irish poets show the successful model for appropiating 'the third-space' of Homi Bhabha. They explore 'the third-space' of Homi Bhabha as the space of recreation, not that of imitation, by solidifying the local culture and accepting the hybridity at the same time. W.B. Yeats is the first contributor in making differentiation of the Irish culture from the English one. And, also, he tries to make the Irish culture global trend. He recreated hybridity as something new. However, he cannot narrow the cultural gap between the Anglo-Irish as a global power and the Gaelic Catholic as a local power. John Montague begins his career as a critic of Irish local culture. And he chose the exile. However, from him, we can also see the romantic attachment to the local culture through its objectification. Seamus Heaney begins his career as an archeologist of the local culture. However he also experiences the conflict between the local and the global. At last his recognition of hybridity of the local culture brings him to the reconciliation. The last conclusion is the following: the three Irish poets go beyond globalism toward glocalism through redefining and remaking their local culture.
