The controversy with Mr. Johnson had its origin in the difference of opinion as to the nature of the Government. That difference led him to the conclusion that the rebellion had not worked any change in the legal relations of the seceding States to the National Government. His motto was this: "Once a State, always a State," whatever might be its conduct either of peace or war. There were, however, differences of opinion among those who adhered to the Republican Party. Mr. Stevens, who was a recognized, if not the recognized, leader of the Republican Party, advocated the doctrine that the eleven States were to be treated as enemy's territory, and to be governed upon whatever system might be acceptable to the States that had remained true to the Union. Mr. Sumner maintained the doctrine that the eleven States were Territories, and that they were to be subject to the General Government until Congress should admit the several Territories as State organizations. The fourth day of May, 1864, I presented a series of resolutions in the House of Representatives, in which I asserted this doctrine: The communities that have been in rebellion can be organized into States only by the will of the loyal people expressed freely and in the absence of all coercion; that States so organized can become States of the American Union only when they shall have applied for admission and their admission shall have been authorized by the existing National Government. A small number of persons who were identified with the Republican Party sustained the policy of Mr. Johnson. Others were of the opinion that the eleven States were out of their proper relation to the Union, as was declared by Mr. Lincoln in his last speech, and that they could become members of the American Union only by the organized action of each, and the concurrent action of the existing National Government. The Government was reorganized without any distinct declaration upon the question whether the States that had been in rebellion were to be treated as enemy's territory, or as Territories according to the usage of former times. The difference of opinion was a vital one with Mr. Johnson. Whatever view may be taken of his moral qualities, it is to be said that he was not deficient in intellectual ability, that his courage passed far beyond the line of obstinacy, and that from the first to last he was prepared to resist the claims of the large majority of the Republican Party. The issue began with his proclamation of May, 1865, and the contest continued to the end of his term. The nature of the issue explains the character and violence of his speeches, especially that of the twenty-second day of February, 1866, when he spoke of Congress as a "body hanging on the verge of the Government."
