The culture of Ireland refers to the idiosyncratic cultural norms of Ireland and the Irish people. The culture of the people living in the island of Ireland is far from monolithic, due to various plantations down through the centuries. Notable cultural divides exist between urban Irish and rural Irish, between the Catholic and Protestant people of Northern Ireland, between the Irish-speaking people inside and outside the Gaeltacht regions and the English-speaking majority population, increasingly between new immigrants and the native population, and most strikingly, the traveller population and the settled population throughout the island. Halloween is a traditional and much celebrated holiday in Ireland on the night of Oct 31. The primary religion in the Republic of Ireland is Christianity. Irish Christianity is dominated by the Roman Catholic Church. Historically, prior to the arrival of Christianity, Celtic polytheism was the dominant religion of the nation. Pub culture, as it is termed, pervades Irish society, across all cultural divides. The term refers to the Irish habit of frequenting public houses (pubs) or bars.
