Most Americans are familiar with the Pilgrim's Thanksgiving Feast of 1621, but few realize that it was not the first festival of its kind in North America. Long before Europeans set foot in the Americas, native peoples sought to insure a good harvest with dances and rituals such as the Green Corn Dance of the Cherokees.
The first Thanksgiving service known to be held by Europeans in North America occurred on May 27, 1578, in Newfoundland, although earlier Church-type services were probably held by Spaniards in La Florida. However, for British New England, some historians believe that the Popham Colony in Maine conducted a Thanksgiving service in 1607 (see Sources: Greif, 208-209; Gould, and Hatch). In the same year, Jamestown colonists gave thanks for their safe arrival, and another service was held in 1610 when a supply ship arrived after a harsh winter. Berkley Hundred settlers held a Thanksgiving service in accordance with their charter which stated that the day of their arrival in Virginia should be observed yearly as a day of Thanksgiving, but within a few years an Indian uprising ended further services (Dabney). Thus British colonists held several Thanksgiving services in America before the Pilgrim's celebration in 1621.
The Pilgrims, with a puritanical rejection of public religious display, held a non-religious Thanksgiving feast, aside from saying grace. In fact, they seem to have used the three days for feasting, playing games, and even drinking liquor. In 1623, the Pilgrims at Plymouth Plantation, Massachusetts, held another day of Thanksgiving. As a drought was destroying their crops, colonists prayed and fasted for relief; the rains came a few days later. And not long after, Captain Miles Standish arrived with staples and news that a Dutch supply ship was on its way. Because of all this good fortune, colonists held a day of Thanksgiving and prayer on June 30. This 1623 festival appears to have been the origin of our Thanksgiving Day.
