The first Thanksgiving Day was decreed by Governor William Bradford of the Plymouth Colony settlement in July 30, 1623. There were harvest festivals, for plentiful crops because that year the Pilgrim’s fall harvest was very successful after a period of drought. There was corn, fruits, vegetables, along with fish, and meat that was smoke cured over fires. The Governor proclaimed a day of thanksgiving that was to be shared by all the colonists and the neighboring Native American Indians. But this was just a one-time event.
It wasn't until 1863 that President Abraham Lincoln prclaimed thanksgiving a national holiday. Since then each president has issued a Thanksgiving Day proclamation, usually designating the fourth Thursday of each November as the holiday for Thanksgiving in the U.S.A. Canada celebrates thanksgiving the second Monday in October.
