The origin of Thanksgiving in the United States traces back to early 17th-century Pilgrims, who celebrated the harvest with the Wampanoag tribe. This event, often considered a feast of gratitude, symbolizes cooperation and survival. Originally marked in Plymouth, Massachusetts, Thanksgiving has evolved into a national holiday characterized by family gatherings, expressive gratitude, and shared meals, particularly featuring turkey. Over time, it has also become a period for reflection on the historical complexities between settlers and indigenous communities, emphasizing themes of gratitude and unity.
