Abraham Lincoln’s 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, tranquility 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.
Abraham Lincoln

Remarks of President Barack Obama Weekly Address, Thursday, November 24, 2011
From my family to yours, I’d like to wish you a happy Thanksgiving. Like millions of Americans, Michelle, Malia, Sasha and I will spend the day eating great food, watching a little football, and reflecting on how truly lucky we truly are.
As Americans, each of us has our own list of things and people to be thankful for. But there are some blessings we all share.
We’re especially grateful for the men and women who defend our country overseas. To all the service members eating Thanksgiving dinner far from your families: the American people are thinking of you today. And when you come home, we intend to make sure that we serve you as well as you’re serving America.
We’re also grateful for the Americans who are taking time out of their holiday to serve in soup kitchens and shelters, making sure their neighbors have a hot meal and a place to stay. This sense of mutual responsibility – the idea that I am my brother’s keeper; that I am my sister’s keeper – has always been a part of what makes our country special. And it’s one of the reasons the Thanksgiving tradition has endured.
The very first Thanksgiving was a celebration of community during a time of great hardship, and we have followed that example ever since. Even when the fate of our union was far from certain – during a Civil War, two World Wars, a Great Depression – Americans drew strength from each other. They had faith that tomorrow would be better than today.
We’re grateful that they did. As we gather around the table, we pause to remember the pilgrims, pioneers, and patriots who helped make this country what it is. They faced impossible odds, and yet somehow, they persevered. Today, it’s our turn.
I know that for many of you, this Thanksgiving is more difficult than most. But no matter how tough things are right now, we still give thanks for that most American of blessings, the chance to determine our own destiny. The problems we face didn’t develop overnight, and we won’t solve them overnight. But we will solve them. All it takes is for each of us to do our part.
With all the partisanship and gridlock here in Washington, it’s easy to wonder if such unity is really possible. But think about what’s happening at this very moment: Americans from all walks of life are coming together as one people, grateful for the blessings of family, community, and country.
If we keep that spirit alive, if we support each other, and look out for each other, and remember that we’re all in this together, then I know that we too will overcome the challenges of our time.
So today, I’m thankful to serve as your President and Commander-and-Chief. I’m thankful that my daughters get to grow up in this great country of ours. And I’m thankful for the chance to do my part, as together, we make tomorrow better than today.
Thanks, and have a wonderful Thanksgiving.
