There is one day a year when all Americans stay home with their families and eat a big dinner. This is Thanksgiving Day. The pilgrims celebrated the first Thanksgiving Day in the fall of 1621. The pilgrims sailed to America on board the "Mayflower" ship for religious freedom. They were among the first European settlers in America. There were people living in America before the pilgrims arrived. These people were the Native American Indians. The pilgrims first winter in the New World was very difficult. They had arrived too late to grow many crops. Without fresh food half of the pilgrims died. The following spring the Indians taught the pilgrims how to hunt, fish, plant and survive in America. The crops did well and in the fall of 1621 pilgrims had a great harvest. They were thankful and decided to celebrate with a Thanksgiving feast. They prepared a dinner of turkey, corn, beans and pumpkins. They invited their Indian friends to share this feast. The Indians brought food for the feast too (they even brought popcorn! ). Americans still celebrate Thanksgiving Day in the fall. It is celebrated on the fourth Thursday in November. Turkey is still the main dish and pumpkin pie is the most popular dessert.
