Irish immigrants are individuals who moved from Ireland to other countries, particularly during the 19th and early 20th centuries. Many left due to the Great Famine in the 1840s, which caused widespread hunger and poverty. They sought better opportunities in places like the United States, where they contributed to the workforce and cultural landscape. Upon arriving, Irish immigrants often faced discrimination and hardship. They typically settled in urban areas, working in factories, construction, and domestic service. Over time, they established vibrant communities, influencing American culture through music, traditions, and celebrations like St. Patrick's Day.
