My understanding is that the Republican party had as its foundation a platform of unconditional Union.

REPUBLICAN NATIONAL PLATFORM ADOPTED AT CHICAGO, 1860
Resolved, That we, the delegated representatives of the Republican electors of the United States, in Convention assembled, in discharge of the duty we owe to our constituents and our country, unite in the following declarations:
2. That the maintenance of the principles promulgated in the Declaration of Independence and embodied in the Federal Constitution, "That all men are created equal; that they are endowed by their Creator with certain inalienable rights; that among these are life, liberty, and the pursuit of happiness; that to secure these rights, governments are instituted among men, deriving their just powers from the consent of the governed," is essential to the preservation of our Republican institutions; and that the Federal Constitution, the Rights of the States, and the Union of the States, must and shall be preserved.
3. That to the Union of the States this nation owes its unprecedented increase in population, its surprising development of material resources, its rapid augmentation of wealth, its happiness at home and its honor abroad; and we hold in abhorrence all schemes for Disunion, come from whatever source they may: And we congratulate the country that no Republican member of Congress has uttered or countenanced the threats of Disunion so often made by Democratic members without rebuke and with applause from their political associates; and we denounce those threats of Disunion, in case of a popular overthrow of their ascendency, as denying the vital principles of a free government, and as an avowal of contemplated treason, which it is the imperative duty of an indignant People sternly to rebuke and forever silence.
Case closed.
Verdict ... error.
