Final answer:
New York was the first state to officially adopt an annual Thanksgiving holiday. This practice was different from the 1621 harvest feast celebrated by the Pilgrims and Indians, which was not an official annual holiday. The national Thanksgiving Day was later proclaimed by Abraham Lincoln in 1863.
Step-by-step explanation:
The first state to adopt an annual Thanksgiving holiday was New York. While the Pilgrims and Indians celebrated a harvest feast in 1621, which we often refer to as the 'first Thanksgiving,' it wasn't declared as an annual holiday until much later. Various individual colonies and states celebrated Thanksgiving on different dates throughout the 17th and 18th centuries.
It was during the American Revolution that the Continental Congress designated one or more days of thanksgiving a year, and in 1789 George Washington issued the first Thanksgiving proclamation by the national government of the United States. However, it wasn't until the 19th century that annual celebrations became a common practice.
New York was the first among several states to officially adopt an annual Thanksgiving holiday, with each state scheduling its own holiday on different dates. It was not until 1863, during the Civil War, that President Abraham Lincoln proclaimed a national Thanksgiving Day to be held each November in the hopes of uniting the divided country.
