Thanksgiving was first celebrated in 1621 by the Dutch settlers at Plymouth, Massachusetts to celebrate a successful harvest. It was a tradition that the Pilgrims brought with them from Europe. After the birth of the United States, President George Washington issued a proclamation honoring the Thanksgiving harvest during his presidency. The only other president to issue a Thanksgiving proclamation was President James Madison.

As part of his attempt to maintain the union, President Abraham Lincoln issued a proclamation that made Thanksgiving Day a national holiday in 1863.

After Lincoln’s proclamation, it was traditional to celebrate Thanksgiving on the last Thursday of November. In a move to increase the holiday shopping period to promote more spending, President Franklin D. Roosevelt pushed to have congress pass a law to move Thanksgiving earlier in the month. In December 1941, Roosevelt signed a bill that set Thanksgiving as the fourth Thursday in November.
