The first Thanksgiving was celebrated by pilgrims in autumn of 1621. They were European travelers who sailed on “Mayflower” ship and tried to find the New World. Before their arrival to America the country was inhabited by Native American Indians. However, when they settled here, life was quite difficult. There was nothing to eat and nowhere to live. First winter was especially difficult and many people couldn’t survive without fresh food. In spring Native Indians taught pilgrims how to survive in America. They now could hunt, fish and grow plants. In the autumn of 1621 they had a wonderful harvest. To celebrate this occasion pilgrims decided to have a Thanksgiving feast. It meant that they were very thankful for their food. During this holiday the tables were full of fresh food: corn, beans, turkey, venison, pumpkin. Their Indian friends were also invited to share the feast. Nowadays Americans continue celebrating this holiday and the main dish is still turkey. The most popular dessert is a pumpkin pie. People in Canada also celebrate Thanksgiving but it falls on every second Thursday of October.
