Thanksgiving Day. November 26, 1789.

Setting aside time to give thanks for one’s blessings, along with holding feasts to celebrate a harvest, are both practices that long predate the European settlement of North America. The first documented thanksgiving services in territory currently belonging to the United States were conducted by Spaniards and the French in the 16th century.

Thanksgiving services were routine in what became the Commonwealth of Virginia as early as 1607, with the first permanent settlement of Jamestown, Virginia holding a thanksgiving in 1610. In 1619, 38 English settlers arrived at Berkeley Hundred in Charles City County, Virginia. The group’s London Company charter specifically required “that the day of our ships arrival at the place assigned… in the land of Virginia shall be yearly and perpetually kept holy as a day of thanksgiving to Almighty God.” Three years later, after the Indian massacre of 1622, the Berkeley Hundred site and other outlying locations were abandoned and colonists moved their celebration to Jamestown and other more secure spots.

The most prominent historic thanksgiving event in American popular culture is the 1621 celebration at the Plymouth Plantation, where the settlers held a harvest feast after a successful growing season. Autumn or early winter feasts continued sporadically in later years, first as an impromptu religious observance and later as a civil tradition.

The Plymouth settlers, known as Pilgrims, had settled in land abandoned when all but one of the Patuxet Indians died in a plague. After a harsh winter killed half of the Plymouth settlers, the last surviving Patuxet, Squanto (who had learned English and avoided the plague as a slave in Europe), came in at the request of Samoset, the first native American to encounter the Pilgrims. Squanto taught the Pilgrims how to catch eel and grow corn and served as an interpreter for them until he too succumbed to plague a year later.

The Wampanoag leader Massqasoit also gave food to the colonists during the first winter when supplies brought from England were insufficient.

William Bradford, in Of Plymouth Plantation wrote:

They began now to gather in the small harvest they had, and to fit up their houses and dwellings against winter, being all well recovered in health and strength and had all things in good plenty. For as some were thus employed in affairs abroad, others were exercised in fishing, about cod and bass and other fish, of which they took good store, of which every family had their portion. All the summer there was no want; and now began to come in store of fowl, as winter approached, of which this place did abound when they can be used (but afterward decreased by degrees). And besides waterfowl there was great store of wild turkeys, of which they took many, besides venison, etc. Besides, they had about a peck a meal a week to a person, or now since harvest, Indian corn to the proportion. Which made many afterwards write so largely of their plenty here to their friends in England, which were not feigned but true reports.

Referring to the 1623 harvest after a nearly catastrophic drought, Bradford wrote:

And afterwards the Lord sent them such seasonable showers, with interchange of fair warm weather as, through His blessing, caused a fruitful and liberal harvest, to their no small comfort and rejoicing. For which mercy, in time convenient, they also set apart a day of thanksgiving… By this time harvest was come, and instead of famine now God gave them plenty … for which they blessed God. And the effect of their particular planting was well seen, for all had … pretty well … so as any general want or famine had not been amongst them since to this day.

President John F. Kennedy issued Proclamation 3560 on November 5, 1963 stating,

“Over three centuries ago, our forefathers in Virginia and in Massachusetts, far from home in a lonely wilderness, set aside a time of thanksgiving. On the appointed day, they gave reverent thanks for their safety, for the health of their children, for the fertility of their fields, for the love which bound them together and for the faith which united them with their God.”

As President, on October 3, 1789, George Washington made the following proclamation and created the first Thanksgiving Day designated by the national government of the United States of America:

Whereas it is the duty of all Nations to acknowledge the providence of Almighty God, to obey his will, to be grateful for his benefits, and humbly to implore his protection and favor, and whereas both Houses of Congress have by their joint Committee requested me “to recommend to the People of the United States a day of public thanksgiving and prayer to be observed by acknowledging with grateful hearts the many signal favors of Almighty God especially by affording them an opportunity peaceably to establish a form of government for their safety and happiness.”

Now therefore I do recommend and assign Thursday the 26th day of November next to be devoted by the People of these States to the service of that great and glorious Being, who is the beneficent Author of all the good that was, that is, or that will be. (…)

Given under my hand at the City of New York the third day of October in the year of our Lord 1789.

Abraham Lincoln‘s successors as president followed his example of annually declaring the final Thursday in November to be Thanksgiving. But in 1939, President Franklin D. Roosevelt broke with this tradition. November had five Thursdays that year (instead of the more-common four), Roosevelt declared the fourth Thursday as Thanksgiving rather than the fifth one. Although many popular histories state otherwise, he made clear that his plan was to establish the holiday on the next-to-last Thursday in the month instead of the last one. With the country still in the midst of The Great Depression, Roosevelt thought an earlier Thanksgiving would give merchants a longer period to sell goods before Christmas. Increasing profits and spending during this period, Roosevelt hoped, would help bring the country out of the Depression.
