The origin of Thanksgiving can be traced back to the beginning of American history, originating from the early immigrants in Plymouth, Massachusetts. These immigrants were called Puritans when they were in the UK. Because they were dissatisfied with the incomplete religious reform of the Church of England, as well as the political suppression and religious persecution of them by the King of England and the Church of England, these Puritans broke away from the Church of England and went to the Netherlands. Later, he decided to move to the uninhabited land on the other side of the Atlantic Ocean, hoping to live religiously and freely according to his own wishes.

In 1620, the famous "Mayflower" ship arrived in America with 102 Puritans who could not endure the religious persecution in Britain. In the winter between 1620 and 1621, they met refugees and brought them daily necessities. They also sent people to teach them how to hunt, fish, and grow corn and pumpkins. With the help of the Indians, the immigrants finally got a good harvest. On the day of celebrating the harvest, according to religious traditions and customs, the immigrants set a day to thank God, and decided to thank the Indians for their sincere help and invite them to celebrate the festival together.

On Thursday in late November 1621, the Pilgrims and 90 Indians brought by Massassod gathered together to celebrate the first Thanksgiving in American history.
