Thanksgiving traces back to 1621, when the Pilgrims (English settlers at Plymouth) held a harvest feast after surviving their first difficult year.
They were helped by the Wampanoag people, especially Squanto, who taught them how to grow corn, fish, and survive the harsh climate.
The 1621 meal lasted three days and likely included venison, corn, and wild fowl — not the foods we typically imagine today.
This event is often called the “First Thanksgiving,” though similar harvest festivals existed long before in many cultures.
EVOLVING TRADITIONS IN
Colonial America
Thanksgiving was not an annual or nationwide holiday at first; colonies held their own days of thanks for harvests, military victories, or survival.
The idea of a Thanksgiving celebration spread through New England, becoming a more regular fall tradition by the late 1600s.
Meals focused on what was locally available rather than the modern standardized dishes.
Native–colonist relationships were complex: moments of cooperation existed, but conflict and displacement soon followed, adding difficult historical context.
Becoming a National Holiday
During the American Revolution, the Continental Congress declared several national days of thanksgiving to boost unity.
In the 1800s, writer Sarah Josepha Hale (author of “Mary Had a Little Lamb”) campaigned for a permanent national holiday.
President Abraham Lincoln, influenced by Hale, declared Thanksgiving a national holiday in 1863, during the Civil War, to promote national healing.
Lincoln set the holiday on the last Thursday of November, which remained until the 20th century.
Modern Thanksgiving AND ITS
Complex Legacy
In 1941, President Franklin D. Roosevelt officially established Thanksgiving as the fourth Thursday of November.
Modern traditions include turkey dinners, parades, football games, and family gatherings.
For many Native American communities, the day is also a reminder of loss, colonization, and broken treaties; some observe it as a National Day of Mourning.
Today, Thanksgiving is both a celebration of gratitude and a time to reflect on the full, complex history behind the holiday.
