Thanksgiving Observances Before the National Holiday
The history of Thanksgiving as a national holiday is different from the history of the Plymouth gathering associated with 1621. Communities observed religious days of thanksgiving before the United States existed. Such occasions were not necessarily annual, autumnal, or centered on a familiar menu. They might respond to a harvest, military victory, or perceived deliverance from danger. 1
The gathering at Plymouth in 1621 became important to later holiday storytelling, but it did not establish the modern federal observance. This article follows the political creation of the national holiday; the distinct history of that gathering and Wampanoag perspectives requires its own treatment. 1
Proclamations and a campaign for an annual day
George Washington issued a national thanksgiving proclamation in 1789. Later presidential and state observances remained inconsistent. A proclamation for a particular year should not be mistaken for legislation fixing a permanent annual date. 12
In the nineteenth century, editor Sarah Josepha Hale promoted a shared national Thanksgiving. Her campaigning connected domestic customs, publishing, and a vision of national unity. The holiday’s emergence depended partly on this sustained cultural work, rather than solely on a president’s spontaneous decision. 1
Lincoln’s Civil War proclamation
In October 1863, Abraham Lincoln called for a day of thanksgiving on the last Thursday of November. Issued during the Civil War, the proclamation combined gratitude with mourning and an appeal for healing. It helped establish the annual presidential practice familiar in later decades. 2
The language of unity should not obscure the violence of the period or erase Native perspectives. For many Indigenous people, Thanksgiving’s celebratory national narrative conceals dispossession. The National Day of Mourning, first held in Plymouth in 1970, publicly challenged that narrative. 3
How the fourth Thursday became fixed
In 1939, Franklin D. Roosevelt moved Thanksgiving earlier, partly to extend the Christmas shopping season. Conflicting observances followed because not all states adopted the change. A holiday presented as a timeless tradition became the subject of an immediate political and commercial dispute. 2
Congress resolved the date in 1941 by establishing the fourth Thursday in November. This is different from both the last Thursday and a guaranteed fourth week following a particular historic feast. The modern holiday combines this legal calendar with customs and interpretations that have continued to evolve. 2
