Ulysses S. Grant: State

1870s, Speech to the Society of the Army of Tennessee (1875)
Context: Encourage free schools, and resolve that not one dollar of money shall be appropriated to the support of any sectarian school. Resolve that neither the state nor nation, or both combined, shall support institutions of learning other than those sufficient to afford every child growing up in the land the opportunity of a good common school education, unmixed with sectarian, Pagan, or Atheistical tenets. Leave the matter of religion to the family altar, the church, and the private school, supported entirely by private contributions. Keep the church and the state forever separate. With these safeguards, I believe the battles which created the Army of the Tennessee will not have been fought in vain.

1860s
Context: I feel no inclination to retaliate for the offences of irresponsible persons; but if it is the policy of any General intrusted with the command of troops to show no quarter, or to punish with death prisoners taken in battle, I will accept the issue. It may be you propose a different line of policy towards black troops, and officers commanding them, to that practiced towards white troops. So, I can assure you that these colored troops are regularly mustered into the service of the United States. The Government, and all officers under the Government, are bound to give the same protection to these troops that they do to any other troops.

1870s, Seventh State of the Union Address (1875)
Context: As the primary step, therefore, to our advancement in all that has marked our progress in the past century, I suggest for your earnest consideration, and most earnestly recommend it, that a constitutional amendment be submitted to the legislatures of the several States for ratification, making it the duty of each of the several States to establish and forever maintain free public schools adequate to the education of all the children in the rudimentary branches within their respective limits, irrespective of sex, color, birthplace, or religions; forbidding the teaching in said schools of religious, atheistic, or pagan tenets; and prohibiting the granting of any school funds or school taxes, or any part thereof, either by legislative, municipal, or other authority, for the benefit or in aid, directly or indirectly, of any religious sect or denomination, or in aid or for the benefit of any other object of any nature or kind whatever.

1880s, Personal Memoirs of General U. S. Grant (1885)
Context: The winter of 1860-1 will be remembered by middle-aged people of to-day as one of great excitement. South Carolina promptly seceded after the result of the Presidential election was known. Other Southern States proposed to follow. In some of them the Union sentiment was so strong that it had to be suppressed by force. Maryland, Delaware, Kentucky and Missouri, all Slave States, failed to pass ordinances of secession; but they were all represented in the so-called congress of the so-called Confederate States. The Governor and Lieutenant-Governor of Missouri, in 1861, Jackson and Reynolds, were both supporters of the rebellion and took refuge with the enemy. The governor soon died, and the lieutenant-governor assumed his office; issued proclamations as governor of the State; was recognized as such by the Confederate Government, and continued his pretensions until the collapse of the rebellion. The South claimed the sovereignty of States, but claimed the right to coerce into their confederation such States as they wanted, that is, all the States where slavery existed. They did not seem to think this course inconsistent. The fact is, the Southern slave-owners believed that, in some way, the ownership of slaves conferred a sort of patent of nobility—a right to govern independent of the interest or wishes of those who did not hold such property. They convinced themselves, first, of the divine origin of the institution and, next, that that particular institution was not safe in the hands of any body of legislators but themselves.

1870s, Message to the Senate and House of Representatives (1870)
Context: A measure which makes at once 4,000,000 people voters who were heretofore declared by the highest tribunal in the land not citizens of the United States, nor eligible to become so (with the assertion that "at the time of the Declaration of Independence the opinion was fixed and universal in the civilized portion of the white race, regarded as an axiom in morals as well as in politics, that black men had no rights which the white man was bound to respect"), is indeed a measure of grander importance than any other one act of the kind from the foundation of our free Government to the present day.

1870s, Sixth State of the Union Address (1874)
Context: Enjoined by the Constitution 'to take care that the laws be faithfully executed', and convinced by undoubted evidence that violations of said act had been committed and that a widespread and flagrant disregard of it was contemplated, the proper officers were instructed to prosecute the offenders, and troops were stationed at convenient points to aid these officers, if necessary, in the performance of their official duties. Complaints are made of this interference by Federal authority; but if said amendment and act do not provide for such interference under the circumstances as above stated, then they are without meaning, force, or effect, and the whole scheme of colored enfranchisement is worse than mockery and little better than a crime. Possibly Congress may find it due to truth and justice to ascertain, by means of a committee, whether the alleged wrongs to colored citizens for political purposes are real or the reports thereof were manufactured for the occasion.

Conclusion
1880s, Personal Memoirs of General U. S. Grant (1885)
Context: The cause of the great War of the Rebellion against the United States will have to be attributed to slavery. For some years before the war began it was a trite saying among some politicians that 'A state half slave and half free cannot exist.' All must become slave or all free, or the state will go down. I took no part myself in any such view of the case at the time, but since the war is over, reviewing the whole question, I have come to the conclusion that the saying is quite true.

1870s, Letter to Daniel Ammen (1877)
Context: For the last eight weeks I have seen but few American papers, and am consequently behind in home news. The foreign papers, however, have been full of the great railroad strike, and no doubt exaggerated it, bad as it was. The United States should always be prepared to put down such demonstrations promptly and with severe consequences for the guilty. I hope good may come out of this, in pointing out the necessity for having the proper remedy at hand in case of need. 'An ounce of preservation is worth a pound of cure'.

1870s, Letter to Daniel Ammen (1877)
Context: There is no more beautiful scenery or climate for summer travel than Switzerland presents. The people are industrious and honest, simple and frugal in their habits, and would be very poor with all this, if it were not from the travel through their country. I wish their surplus population would emigrate to the United States.

1880s, Personal Memoirs of General U. S. Grant (1885)
Context: Slavery was an institution that required unusual guarantees for its security wherever it existed; and in a country like ours where the larger portion of it was free territory inhabited by an intelligent and well-to-do population, the people would naturally have but little sympathy with demands upon them for its protection. Hence the people of the South were dependent upon keeping control of the general government to secure the perpetuation of their favorite institution. They were enabled to maintain this control long after the States where slavery existed had ceased to have the controlling power, through the assistance they received from odd men here and there throughout the Northern States. They saw their power waning, and this led them to encroach upon the prerogatives and independence of the Northern States by enacting such laws as the Fugitive Slave Law. By this law every Northern man was obliged, when properly summoned, to turn out and help apprehend the runaway slave of a Southern man. Northern marshals became slave-catchers, and Northern courts had to contribute to the support and protection of the institution.

1860s, First State of the Union Address (1869)
Context: As the United States is the freest of all nations, so, too, its people sympathize with all people struggling for liberty and self-government; but while so sympathizing it is due to our honor that we should abstain from enforcing our views upon unwilling nations and from taking an interested part, without invitation, in the quarrels between different nations or between governments and their subjects. Our course should always be in conformity with strict justice and law, international and local.

1870s, Seventh State of the Union Address (1875)
Context: I am happy to announce the passage of an act by the General Cortes of Portugal, proclaimed since the adjournment of Congress, for the abolition of servitude in the Portuguese colonies. It is to be hoped that such legislation may be another step toward the great consummation to be reached, when no man shall be permitted, directly or indirectly, under any guise, excuse, or form of law, to hold his fellow-man in bondage. I am of opinion also that it is the duty of the United States, as contributing toward that end, and required by the spirit of the age in which we live, to provide by suitable legislation that no citizen of the United States shall hold slaves as property in any other country or be interested therein.
