Thanksgiving Day, annual national holiday in the United States and Canada celebrating the harvest and other blessings of the past year. Americans generally believe that their Thanksgiving is modeled on a 1621 harvest feast shared by the English colonists (Pilgrims) of Plymouth and the Wampanoag people. The American holiday is particularly rich in legend and symbolism, and the traditional fare of the Thanksgiving meal typically includes turkey, bread stuffing, potatoes, cranberries, and pumpkin pie. With respect to vehicular travel, the holiday is often the busiest of the year, as family members gather with one another.

Top Questions What is Thanksgiving? Thanksgiving is an annual national holiday in the United States and Canada celebrating the harvest and other blessings of the past year. How did Thanksgiving start? Colonists in New England and Canada regularly observed “thanksgivings,” days of prayer for such blessings as safe journeys, military victories, or abundant harvests. Americans model their holiday on a 1621 harvest feast shared between English colonists and the Wampanoag. Canadians trace their earliest thanksgiving to 1578 when a Martin Frobisher-led expedition celebrated safe passage. How is Thanksgiving celebrated? In both Canada and America, family and friends gather for a feast on the holiday. Traditional fare in America typically includes turkey, cranberries, and pumpkin pie. The holiday moved away from its religious roots over time, allowing immigrants of every background to participate in a common tradition. How did Thanksgiving become a national holiday? Writer Sarah Josepha Hale campaigned for a national Thanksgiving in the United States during the 19th century, eventually winning President Abraham Lincoln’s support in 1863. He and subsequent presidents proclaimed a national day of thanksgiving annually until 1941 when Congress made Thanksgiving official. In Canada, Parliament established a national Thanksgiving Day in 1879. How is Thanksgiving determined? In 1941 President Franklin D. Roosevelt issued a proclamation designating the fourth Thursday in November as Thanksgiving Day in the United States. Since 1957, Thanksgiving Day has been celebrated in Canada on the second Monday in October.

Plymouth’s Thanksgiving began with a few colonists going out “fowling,” possibly for turkeys but more probably for the easier prey of geese and ducks, since they “in one day killed as much as…served the company almost a week.” Next, 90 or so Wampanoag made a surprise appearance at the settlement’s gate, doubtlessly unnerving the 50 or so colonists. Nevertheless, over the next few days the two groups socialized without incident. The Wampanoag contributed venison to the feast, which included the fowl and probably fish, eels, shellfish, stews, vegetables, and beer. Since Plymouth had few buildings and manufactured goods, most people ate outside while sitting on the ground or on barrels with plates on their laps. The men fired guns, ran races, and drank liquor, struggling to speak in broken English and Wampanoag. This was a rather disorderly affair, but it sealed a treaty between the two groups that lasted until King Philip’s War (1675–76), in which hundreds of colonists and thousands of Native Americans lost their lives.

The New England colonists were accustomed to regularly celebrating “Thanksgivings,” days of prayer thanking God for blessings such as military victory or the end of a drought. The U.S. Continental Congress proclaimed a national Thanksgiving upon the enactment of the Constitution, for example. Yet, after 1798, the new U.S. Congress left Thanksgiving declarations to the states; some objected to the national government’s involvement in a religious observance, Southerners were slow to adopt a New England custom, and others took offense over the day’s being used to hold partisan speeches and parades. A national Thanksgiving Day seemed more like a lightning rod for controversy than a unifying force.

Thanksgiving Day did not become an official holiday until Northerners dominated the federal government. While sectional tensions prevailed in the mid-19th century, the editor of the popular magazine Godey’s Lady’s Book, Sarah Josepha Hale, campaigned for a national Thanksgiving Day to promote unity. She finally won the support of President Abraham Lincoln. On October 3, 1863, during the Civil War, Lincoln proclaimed a national day of thanksgiving to be celebrated on Thursday, November 26.

The holiday was annually proclaimed by every president thereafter, and the date chosen, with few exceptions, was the last Thursday in November. President Franklin D. Roosevelt, however, attempted to extend the Christmas shopping season, which generally begins with the Thanksgiving holiday, and to boost the economy by moving the date back a week, to the third week in November. But not all states complied, and, after a joint resolution of Congress in 1941, Roosevelt issued a proclamation in 1942 designating the fourth Thursday in November (which is not always the last Thursday) as Thanksgiving Day.

As the country became more urban and family members began to live farther apart, Thanksgiving became a time to gather together. The holiday moved away from its religious roots to allow immigrants of every background to participate in a common tradition. Thanksgiving Day football games, beginning with Yale versus Princeton in 1876, enabled fans to add some rowdiness to the holiday. In the late 1800s parades of costumed revelers became common. In 1920 Gimbel’s department store in Philadelphia staged a parade of about 50 people with Santa Claus at the rear of the procession. Since 1924 the annual Macy’s parade in New York City has continued the tradition, with huge balloons since 1927. The holiday associated with Pilgrims and Native Americans has come to symbolize intercultural peace, America’s opportunity for newcomers, and the sanctity of home and family.

Days of thanksgiving in Canada also originated in the colonial period, arising from the same European traditions, in gratitude for safe journeys, peace, and bountiful harvests. The earliest celebration was held in 1578, when an expedition led by Martin Frobisher held a ceremony in present-day Nunavut to give thanks for the safety of its fleet. In 1879 Parliament established a national Thanksgiving Day on November 6; the date has varied over the years. Since 1957 Thanksgiving Day has been celebrated in Canada on the second Monday in October.
