Halloween did not become a holiday in the United States until the 19th century, where lingering Puritan tradition restricted the observance of many holidays. American almanacs of the late 18th and early 19th centuries do not include Halloween in their lists of holidays. The transatlantic migration of nearly two million Irish following the Irish Potato Famine (1845–1849) finally brought the holiday to the United States. Scottish emigration from the British Isles, primarily to Canada before 1870 and to the United States thereafter, brought the Scottish version of the holiday to each country.
Scottish-American and Irish-American societies held dinners and balls that celebrated their heritages, with perhaps a recitation of Robert Burns' poem "Halloween" or a telling of Irish legends, much as Columbus Day celebrations were more about Italian-American heritage than Columbus per se. Home parties would center around children's activities, such as bobbing for apples, and various divination games often concerning future romance. Not surprisingly, pranks and mischief were common as well.
