Secretary of State William Seward wrote it, and Abraham Lincoln issued it, but much of the credit for the Thanksgiving Proclamation should probably go to a woman named Sarah Josepha Hale.

A prominent writer and editor, Hale had written the children’s poem “Mary Had a Little Lamb,” originally known as “Mary’s Lamb,” in 1830 and helped found the American Ladies Magazine, which she used a platform to promote women’s issues. In 1837, she was offered the editorship of Godey’s Lady Book, where she would remain for more than 40 years, shepherding the magazine to a circulation of more than 150,000 by the eve of the Civil War and turning it into one of the most influential periodicals in the country. 

In addition to her publishing work, Hale was a committed advocate for women’s education (including the creation of Vassar College in Poughkeepsie, New York), and raised funds to construct Massachusetts’s Bunker Hill Monument and save George Washington’s Mount Vernon estate.

The New Hampshire-born Hale had grown up regularly celebrating an annual Thanksgiving holiday, and in 1827 published a novel, Northwood: A Tale of New England, that included an entire chapter about the fall tradition, already popular in parts of the nation. While at Godey’s, Hale often wrote editorials and articles about the holiday and she lobbied state and federal officials to pass legislation creating a fixed, national day of thanks on the last Thursday of November. She believed that such a unifying measure could help ease growing tensions and divisions between the northern and southern parts of the country. Her efforts paid off: By 1854, more than 30 states and U.S. territories had a Thanksgiving celebration on the books, but Hale’s vision of a national holiday remained unfulfilled.

The concept of a national Thanksgiving did not originate with Hale, and in fact the idea had been around since the earliest days of the republic. During the American Revolution, the Continental Congress issued proclamations declaring several days of thanks, in honor of military victories. 

In 1789, a newly inaugurated George Washington called for a national day of thanks to celebrate both the end of the war and the recent ratification of the U.S. Constitution. Both John Adams and James Madison issued similar proclamations of their own, though fellow Founding Father Thomas Jefferson felt the religious connotations surrounding the event were out of place in a nation founded on the separation of church and state, and no formal declarations were issued after 1815.

The outbreak of war in April 1861 did little to stop Sarah Josepha Hale’s efforts to create such a holiday, however. She continued to write editorials on the subject, urging Americans to “put aside sectional feelings and local incidents” and rally around the unifying cause of Thanksgiving. And the holiday continued, despite hostilities, in both the Union and the Confederacy

In 1861 and 1862, Confederate President Jefferson Davis issued Thanksgiving Day proclamations following Southern victories. Abraham Lincoln himself called for a day of thanks in April 1862, following Union victories at Fort Donelson, Fort Henry and at Shiloh, and again in the summer of 1863 after the Battle of Gettysburg.

Shortly after Lincoln’s summer proclamation, Hale wrote to both the president and Secretary of State William Seward, once again urging them to declare a national Thanksgiving, stating that only the chief executive had the power to make the holiday, “permanently, an American custom and institution.” 

Whether Lincoln was already predisposed to issue such a proclamation before receiving Hale’s letter of September 28 remains unclear. What is certain is that within a week, Seward had drafted Lincoln’s official proclamation fixing the national observation of Thanksgiving on the final Thursday in November, a move the two men hoped would help “heal the wounds of the nation.”

After more than three decades of lobbying, Sarah Josepha Hale (and the United States) had a national holiday, though some changes remained in store.

In 1939, President Franklin Roosevelt briefly moved Thanksgiving up a week, in an effort to extend the already important shopping period before Christmas and spur economic activity during the Great Depression

While several states followed FDR’s lead, others balked, with 16 states refusing to honor the calendar shift, leaving the country with dueling Thanksgivings. Faced with increasing opposition, Roosevelt reversed course just two years later, and in the fall of 1941, the U.S. Congress passed a resolution returning the holiday to the fourth Thursday of November.
