But, although the anti-slavery sentiment was not strong enough to embarrass the govern ment in the conduct of the war or to endanger the treaty of peace, still it could not entirely be kept in the background. That was shown, for example, in the struggle over the Wilmot Pro viso. As soon as peace was concluded and it was no longer necessary to keep up the appear ance of unanimity before the enemy, the con troversy was renewed. Three questions came up for solution: Should California be admitted as a free State? Should the remainder of the territory acquired from Mexico be organized in accordance with the Wilmot Proviso? What should be the boundary between Texas and New Mexico? These questions and others con nected with slavery were nominally settled by the compromise of 1850, but the controversy was soon renewed in a more violent form, and culminated in secession, civil war and emanci pation.
