Thousands of Irish left in their homeland in the 18th and 19th centuries to escape the religious and political discrimination they experienced primarily at the hands of the English, and in the search of a plot of land to call their own. These immigrants arrived at the eastern shores of North America, early on settling and breaking the land, and, later, building the bridges, canals, and railroads essential to the emerging nations of United States and Canada.
