Before the establishment of formal religions, many ancient farmers believed that their crops contained spirits which caused the crops to grow and die. Many believed that these spirits would be released when the crops were harvested and they had to be destroyed or they would take revenge on the farmers who harvested them.
Harvest festivals and Thanksgiving celebrations were held by the ancient Greeks, the Romans, the Hebrews, the Chinese, and the Egyptians.
The initial "Thanksgiving" feast in the English colonies - a traditional English harvest celebration - was celebrated in 1621. The Pilgrims shared it with the Native Americans because they had taught the colonists to plants crops and hunt wild game. Without the Native Americans, the Pilgrims may not have survived the harsh winter and been able to celebrate their first harvest of plentiful crops in the New World.
The colonists' first harvest feast lasted for three days. Food was served all at once, instead of in courses, so people ate whatever they pleased in the order that they desired. The more important members at the feast were given the best pieces of meat, while the rest of the diners ate whatever was closest to them.
The history of Thanksgiving demonstrates that feasts like the one at Plymouth were held throughout the colonies after fall harvests. However, all thirteen colonies did not celebrate Thanksgiving at the same time. In 1789, George Washington became the first president to declare Thanksgiving a holiday.
By the mid-1800s, many states observed the Thanksgiving holiday.
Meanwhile, the poet and editor, Sarah J. Hale, had begun lobbying for a national Thanksgiving holiday. During the Civil War President Abraham Lincoln looking for ways to unite the nation, discussed the subject with Hale. In 1863 he gave his Thanksgiving Proclamation declaring the last Thursday in November a day of Thanksgiving.
