This paper aims to shed light on the Northern Irish historical, political and social effects on the poetry written by the great 20^th-century poet, Seamus Heaney. The writer's tremendous concern with the problems facing people in his country and his attempt to connect such affairs with the broad landscape of humanity gave him the chance to get a lofty position among the world's prominent poets. Through his poetry, this noted literary figure tried to draw a vivid picture of the agony of his people due to the sectarian and political struggles in their country. He attempted also to dig deep in history so as to show the misery of people in the past in North Ireland and how they had suffered just like those who lived during his time. Therefore, Heaney's poetry gave a sincere image of life in his homeland.
