The culture of Ireland includes customs and traditions, language, music, art, literature, folklore, cuisine and sports associated with Ireland and the Irish people. For most of its recorded history, Ireland's culture has been primarily Gaelic (see Gaelic Ireland). It has also been influenced by Anglo-Norman, English and Scottish culture. The Anglo-Normans invaded Ireland in the 12th century, while the 16th/17th century conquest and colonization of Ireland saw the emergence of the Anglo-Irish and Scots-Irish (or Ulster Scots). Today, there are notable cultural differences between those of Catholic and Protestant (especially Ulster Protestant) background, and between travellers and the settled population.
Due to large-scale emigration from Ireland, Irish culture has a global reach and festivals such as Saint Patrick's Day, Halloween, are celebrated all over the world. Irish culture has to some degree been inherited and modified by the Irish diaspora, which in turn has influenced the home country.
Though there are many unique aspects of Irish culture, it shares substantial traits with those of Britain, other English-speaking countries, other predominantly Catholic European countries, and the other Celtic nations.
