US Presidency
1849

For more than half a century, during which kingdoms and empires have fallen, this Union has stood unshaken. The patriots who formed it have long since descended to the grave; yet still it remains, the proudest monument to their memory and the object of affection and admiration with everyone worthy to bear the American name. In my judgment its dissolution would be the greatest of calamities, and to avert that should be the study of every American. Upon its preservation must depend our own happiness and that of countless generations to come. Whatever dangers may threaten it, I shall stand by it and maintain it in its integrity to the full extent of the obligations imposed and the powers conferred upon me by the Constitution
