Thanksgiving or Thanksgiving Day, presently celebrated on the fourth Thursday in November, has been an annual tradition in the United States since 1863. It did not become a federal holiday until 1941. Thanksgiving was historically a religious observation to give thanks to God, but is now primarily identified as a secular holiday.

The first Thanksgiving was celebrated to give thanks to God for helping the Pilgrims of Plymouth Colony survive the brutal winter.[citation needed] The first Thanksgiving feast lasted three days providing enough food for 53 pilgrims and 90 Indians. The feast consisted of fowl, venison, fish, lobster, clams, berries, fruit, pumpkin, and squash. However, the traditional Thanksgiving menu often features turkey, stuffing, sweet potatoes and pumpkin pie.

Foods of the season 

U.S. tradition compares the holiday with a meal held in 1621 by the Wampanoag and the Pilgrims who settled in Plymouth, Massachusetts. It is continued in modern times with the Thanksgiving dinner, traditionally featuring turkey, playing a large role in the celebration of Thanksgiving. Some of the details of the American Thanksgiving story are myths that developed in the 1890s and early 1900s as part of the effort to forge a common national identity in the aftermath of the Civil War and in the melting pot of new immigrants.

Traditional Thanksgiving Dinner

In the United States, certain kinds of food are traditionally served at Thanksgiving meals. Firstly, baked or roasted turkey is usually the featured item on any Thanksgiving feast table (so much so that Thanksgiving is sometimes referred to as "Turkey Day"). Stuffing, mashed potatoes with gravy, sweet potatoes, cranberry sauce, sweet corn, other fall vegetables, and pumpkin pie are commonly associated with Thanksgiving dinner. All of these are actually native to the Americas or were introduced as a new food source to the Europeans when they arrived. As an alternative to turkey, many vegetarians or vegans eat tofurky, a meatless turkey made of tofu.

The less fortunate are often provided with food at Thanksgiving time. Most communities have annual food drives that collect non-perishable packaged and canned foods, and corporations sponsor charitable distributions of staple foods and Thanksgiving dinners.
