Proclamation Establishing Thanksgiving Day
October 3, 1863
The year that is drawing towards its close, has been filled with the blessings of fruitful fields and healthful skies. To these bounties, which are so constantly enjoyed that we are prone to forget the source from which they come, others have been added, which are of so extraordinary a nature, that they cannot fail to penetrate and soften even the heart which is habitually insensible to the ever watchful providence of Almighty God. In the midst of a civil war of unequalled magnitude and severity, which has sometimes seemed to foreign States to invite and to provoke their aggression, peace has been preserved with all nations, order has been maintained, the laws have been respected and obeyed, and harmony has prevailed everywhere except in the theatre of military conflict; while that theatre has been greatly contracted by the advancing armies and navies of the Union. Needful diversions of wealth and of strength from the fields of peaceful industry to the national defence, have not arrested the plough, the shuttle, or the ship; the axe had enlarged the borders of our settlements, and the mines, as well of iron and coal as of the precious metals, have yielded even more abundantly than heretofore. Population has steadily increased, notwithstanding the waste that has been made in the camp, the siege and the battle-field; and the country, rejoicing in the consciousness of augmented strength and vigor, is permitted to expect continuance of years, with large increase of freedom.
No human counsel hath devised nor hath any mortal hand worked out these great things. They are the gracious gifts of the Most High God, who, while dealing with us in anger for our sins, hath nevertheless remembered mercy.
It has seemed to me fit and proper that they should be solemnly, reverently and gratefully acknowledged as with one heart and voice by the whole American people. I do therefore invite my fellow citizens in every part of the United States, and also those who are at sea and those who are sojourning in foreign lands, to set apart and observe the last Thursday of November next, as a day of Thanksgiving and Praise to our beneficent Father who dwelleth in the Heavens. And I recommend to them that while offering up the ascriptions justly due to Him for such singular deliverances and blessings, they do also, with humble penitence for our national perverseness and disobedience, commend to his tender care all those who have become widows, orphans, mourners or sufferers in the lamentable civil strife in which we are unavoidably engaged, and fervently implore the interposition of the Almighty Hand to heal the wounds of the nation and to restore it as soon as may be consistent with the Divine purposes to the full enjoyment of peace, harmony, tranquillity and Union.
In testimony whereof, I have hereunto set my hand, and caused the seal of the United States to be affixed.
Done at the city of Washington, this third day of October, in the year of our Lord one thousand eight hundred and sixty-three, and of the independence of the United States the eighty-eighth.
Thanksgiving Day Proclamation 1981
Date: November 12, 1981
By: Ronald Reagan
America has much for which to be thankful. The unequaled freedom enjoyed by our citizens has provided a harvest of plenty to this nation throughout its history. In keeping with America's heritage, one day each year is set aside for giving thanks to god for all of His blessings. On this day of thanksgiving, it is appropriate that we recall the first thanksgiving, celebrated in the autumn of 1621. After surviving a bitter winter, the Pilgrims planted and harvested a bountiful crop. After the harvest they gathered their families together and joined in celebration and prayer with the Native Americans who had taught them so much. Clearly our forefathers were thankful not only for the material well being of their harvest but for this abundance of goodwill as well.
In this spirit, Thanksgiving has become a day when Americans extend a helping hand to the less fortunate. Long before there was a government welfare program, this spirit of voluntary giving was ingrained in the American character. Americans have always understood that, truly, one must give in order to receive. This should be a day of giving as well as a day of thanks. As we celebrate Thanksgiving in 1981, we should reflect on the full meaning of this day as we enjoy the fellowship that is so much a part of the holiday festivities. Searching our hearts, we should ask what we can do sass individuals to demonstrate our gratitude to God for all He has done. Such reflection can only add to the significance of this precious day of remembrance.
Let us recommit ourselves to that devotion to God and family that has played such an important role in making this a great Nation, and which will be needed as a source of strength if we are to remain a great people. Now, Therefore, I, Ronald Reagan, President of the United States of America, do hereby proclaim Thursday, November 26, 1981, as Thanksgiving Day. In witness where of, I have here unto set my hand this twelfth day of November, in the year of our Lord nineteen hundred and eighty-one, and of the Independence of the United States of America the two hundred and sixth.
Hale believed that Thanksgiving would strengthen family traditions, solidify the role of women as mothers, and allay fears about industrialization.
She also penned the famous poem "Mary Had a Little Lamb."
