Congress' Thanksgiving Proclamation, 1782

Do you think Thanksgiving started to thank the Indians (as some textbooks claim)? Or to sell stuff at Best Buy?

Here is what the Library of Congress says about the proclamation for Thanksgiving by our Congress in 1782:

Founders Give Thanks
Following the Revolutionary War, the Continental Congress recognized the need to give thanks for delivering the country from war and into independence. Congress issued a proclamation on October 11, 1782:

By the United States in Congress assembled.

PROCLAMATION.

IT being the indispensable duty of all Nations, not only to offer up their supplications to ALMIGHTY GOD, the giver of all good, for his gracious assistance in a time of distress, but also in a solemn and public manner to give him praise for his goodness in general, and especially for great and signal interpositions of his providence in their behalf: Therefore the United States in Congress assembled, taking into their consideration the many instances of divine goodness to these States, in the course of the important conflict in which they have been so long engaged; the present happy and promising state of public affairs; and the events of the war, in the course of the year now drawing to a close; particularly the harmony of the public Councils, which is so necessary to the success of the public cause; the perfect union and good understanding which has hitherto subsisted between them and their Allies, notwithstanding the artful and unwearied attempts of the common enemy to divide them; the success of the arms of the United States, and those of their Allies, and the acknowledgment of their independence by another European power, whose friendship and commerce must be of great and lasting advantage to these States:----- Do hereby recommend to the inhabitants of these States in general, to observe, and request the several States to interpose their authority in appointing and commanding the observation of THURSDAY the twenty-eight day of NOVEMBER next, as a day of solemn THANKSGIVING to GOD for all his mercies: and they do further recommend to all ranks, to testify to their gratitude to GOD for his goodness, by a cheerful obedience of his laws, and by promoting, each in his station, and by his influence, the practice of true and undefiled religion, which is the great foundation of public prosperity and national happiness.

Done in Congress, at Philadelphia, the eleventh day of October, in the year of our LORD one thousand seven hundred and eighty-two, and of our Sovereignty and Independence, the seventh.

JOHN HANSON, President.

Charles Thomson, Secretary.
