The term "Irish diaspora" refers to the communities of people of Irish descent who have migrated from Ireland to various parts of the world. This movement began in significant numbers during the 19th century, particularly due to events like the Great Famine, which led many to seek better opportunities abroad. Today, the Irish diaspora is found in countries such as the United States, Canada, Australia, and the United Kingdom. The Irish diaspora has played a crucial role in shaping the cultural and social landscapes of their new homes. Many individuals maintain strong connections to their Irish heritage through traditions, language, and celebrations like St. Patrick's Day. The diaspora also contributes to the global economy and fosters international relationships between Ireland and other nations.
