In the United States, the modern
Thanksgiving holiday tradition is commonly, but not universally, traced to a
poorly documented 1621 celebration at Plymouth in present-day Massachusetts. The 1621
Plymouth feast and thanksgiving was prompted by a good harvest.
In
later years, religious thanksgiving services were declared by civil leaders
such as Governor Bradford who planned a thanksgiving celebration
and fast in 1623.[8][9][10] The
practice of holding an annual harvest festival like this did not become a
regular affair in New England until the late 1660s.[11]
Pilgrims and Puritans who began emigrating from
England in the 1620s and 1630s carried the tradition of Days of Fasting and
Days of Thanksgiving with them to New England. Several
days of Thanksgiving were held in early New England history that have been
identified as the "First Thanksgiving", including Pilgrim holidays in Plymouth in 1621 and 1623, and a Puritan
holiday inBoston in 1631.[12][13]
Thanksgiving
proclamations were made mostly by church leaders in New England up until 1682,
and then by both state and church leaders until after the American
Revolution. During the revolutionary period, political influences
affected the issuance of Thanksgiving proclamations. Various proclamations were
made by royal governors, John Hancock, General George Washington, and
the Continental
Congress, each giving thanks to God for events favorable to their
causes.[14] As
President of the United States, George Washington proclaimed the first
nation-wide thanksgiving celebration in America marking November 26, 1789,
"as a day of public thanksgiving and prayer to be observed by
acknowledging with grateful hearts the many and signal favours of Almighty
God".[15]
According
to historian Jeremy Bangs, director of the Leiden American Pilgrim Museum, the Pilgrims
may have been influenced by watching the annual services of Thanksgiving for
the relief of the siege of Leiden in 1574, while they were staying in
Leiden.[16]
Every
year, the President of the United States will "pardon" a turkey,
which spares the bird's life and ensures that it will spend the duration of its
life roaming freely on farmland.[17]
