U.S. President Franklin D. Roosevelt had a lot to think about in 1939. The world had been suffering from the Great Depression for a decade and the Second World War had just erupted in Europe. On top of that, the U.S. economy continued to look bleak. So when U.S. retailers begged him to move Thanksgiving up a week to increase the shopping days before Christmas, he agreed. He probably considered it a small change; however, when FDR issued his Thanksgiving Proclamation with the new date, there was an uproar throughout the country.

The First Thanksgiving

As most schoolchildren know, the history of Thanksgiving began when Pilgrims and Native Americans gathered together to celebrate a successful harvest. The first Thanksgiving was held in the fall of 1621, sometime between September 21 and November 11, and was a three-day feast. The Pilgrims were joined by approximately 90 of the local Wampanoag tribe, including Chief Massasoit, in celebration. They ate fowl and deer for certain and most likely also ate berries, fish, clams, plums, and boiled pumpkin.

Sporadic Thanksgivings

Though the current holiday of Thanksgiving was based on the 1621 feast, it did not immediately become an annual celebration or holiday. Sporadic days of Thanksgiving followed, usually declared locally to give thanks for a specific event such as the end of a drought, victory in a specific battle, or after a harvest.

It wasn’t until October 1777 that all 13 colonies celebrated a day of Thanksgiving. The very first national day of Thanksgiving was held in 1789, when President George Washington proclaimed Thursday, November 26 to be “a day of public thanksgiving and prayer,” to especially give thanks for the opportunity to form a new nation and the establishment of a new constitution.

Yet even after a national day of Thanksgiving was declared in 1789, Thanksgiving was not an annual celebration.
