Irish immigration refers to the movement of people from Ireland to other countries, particularly during the 19th and early 20th centuries. A significant wave occurred during the Great Famine (1845-1852), when millions fled to escape starvation and poverty. Many settled in the United States, where they sought better opportunities and contributed to the workforce. Irish immigrants faced challenges, including discrimination and economic hardship. Despite this, they established vibrant communities, particularly in cities like New York and Boston. Over time, they played a crucial role in shaping American culture, politics, and society, leaving a lasting legacy that continues today.
