Numerous Ohioans are descended from Irish ancestors. Today, Irish Ohioans continue to enhance Ohio's cultural and social landscape.
During the eighteenth, nineteenth, and early twentieth centuries, millions of immigrants migrated to the United States of America, hoping to live the American Dream. Before the American Civil War, most immigrants arrived in the United States from Great Britain, Germany, and Ireland. By the 1880s, the home countries of immigrants began to change. Many of the new immigrants to arrive in the United States came from Eastern European countries, like Poland, Hungary, and Czechoslovakia, rather than from Western European countries, like Great Britain, Ireland, and Germany.
