Irish emigration refers to the movement of people from Ireland to other countries, primarily driven by factors such as economic hardship, political unrest, and famine. The most significant wave occurred during the Great Famine in the mid-19th century, when millions left for places like the United States, Canada, and Australia in search of better opportunities. Over the years, Irish emigrants have contributed to the cultural and economic development of their new countries. Today, the Irish diaspora is widespread, with millions of people of Irish descent living around the world, maintaining connections to their heritage and homeland.
