When did Thanksgiving become a national holiday? Thanksgiving, celebrated in the United States on the fourth Thursday in November has been an annual tradition since 1863. During the Civil War, President Abraham Lincoln proclaimed a national day of “Thanksgiving and Praise to our beneficent Father who dwelleth in the Heavens”, to be celebrated on Thursday, November 26.
The event that Americans commonly call the “First Thanksgiving” was celebrated by the Pilgrims after their first harvest in the New World in 1621. This feast lasted three days, and it was attended by 90 Native Americans (as accounted by attendee Edward Winslow) and 53 Pilgrims. 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. Happy Thanksgiving!
