"Irish American" refers to individuals in the United States who have ancestral roots in Ireland. This cultural group has significantly influenced American society, particularly in areas such as music, literature, and politics. Many Irish immigrants arrived during the 19th century, fleeing famine and seeking better opportunities, which led to the establishment of vibrant Irish communities across the country. The celebration of St. Patrick's Day is one of the most recognized expressions of Irish American culture, featuring parades, music, and traditional foods. Irish Americans have also made notable contributions to various fields, including government, sports, and entertainment, shaping the diverse fabric of American identity.
