It started as a “harvest festival” among recently arrived Pilgrims at Mayflower and their Native American neighbors. However, a short time later it became a Puritanical religious celebration thanking God for the harvest and war victories. It becomes a national holiday on the last Thursday during November during the Civil War.
In modern times, it’s still about giving thanks and a time for family. With a little American football and shop-til-you-drop thrown in. Happy Thanksgiving everyone.
