The Thanksgiving Day is a national american celebration. It originates long time ago. If I`m not mistaken, When the first people started began to settle the land of America, they didn`t have any food and probably they would deie because of hunger. If not the indians, who gave them food. It is assumed that the first food that people got from them was turkey, corn, pumpkin and maple syrup. 
In our days people in America still celebrate Thanksgiving day, mentally thank the God and that indians and eat turkey as a traditional meal on this day.

День Благодарения - национальный американский праздник. Он берёт начало с давних пор. Если я не ошибаюсь, когда первые колонии стали заселять Америку, у них совсем не было еды и, возможно, они бы умерли от голода. Если бы не индейцы, которые дали им еду. Принято считать, что первая еда, которую получили люди - это индейка, кукуруза, тыква и кленовый сироп.
В наши дни люди в Америке до сих пор празднуют День Благодарения, мысленно воздают благодарность Богу и тем индейцам и едят индейку в качестве традиционного блюда в этот день.
