There are claims that the first Thanksgiving Day was held in the city of El Paso, Texas in 1598. Another early event was held in 1619 in the Virginia Colony. Many people trace the origins of the modern Thanksgiving Day to the harvest celebration that the Pilgrims held in Plymouth, Massachusetts in 1621. However, their first true thanksgiving was in 1623, when they gave thanks for rain that ended a drought. These early thanksgivings took the form of a special church service, rather than a feast.
In the second half of the 1600s, thanksgivings after the harvest became more common and started to become annual events. However, it was celebrated on different days in different communities and in some places there were more than one thanksgiving each year. George Washington, the first president of the United States, proclaimed the first national Thanksgiving Day in 1789.
