Geography of Halloween
In the United States, where lingering Puritan tradition restricted the observance of many holidays, Halloween did not become a holiday until the 19th century. The transatlantic migration of nearly two million Irish following the Irish Great Famine (1845–1849) brought the holiday to the United States.
