fugitive slave, overruled any state laws giving sanctuary, made it a federal crime to assist an escaped slave, and allowed slave-catchers into every U.S. state and territory. As free states sought to undermine the federal law, the even more severe Fugitive Slave Act of 1850 was enacted. In 1864, during the Civil War, an effort to repeal this clause of the Constitution failed. The vote in the House was 69 for repeal and 38 against, which was short of the two-to-one vote required to amend the Constitution. This clause was rendered mostly moot when the Thirteenth Amendment abolished slavery. Section 3: New states and federal property Clause 1: Admission of new states The First Clause of Section Three, also known as the Admissions Clause, grants to Congress the authority to admit new states into the Union. Since the establishment of the United States in 1776, the number of states has expanded from the original 13 to 50. It also forbids the creation of new states from parts of existing states without the consent of the affected states and Congress. This latter provision was designed to give Eastern states that still had claims to Western lands (e.g., Virginia and North Carolina) to have a veto over whether their western counties (which eventually became Kentucky and Tennessee) could become states. It would later be applied with regard to the formation of Maine (from Massachusetts) and West Virginia (from Virginia). At the 1787 Constitutional Convention, a proposal to include the phrase, "new States shall be admitted on the same terms with the original States", was defeated. It was feared that the political power of future new western states would eventually overwhelm that of the established eastern states. Once the new Constitution went into effect, however, Congress admitted Vermont and Kentucky on equal terms and thereafter formalized the condition in its acts of admission for subsequent states, declaring that the new state enters "on an equal footing with the original States in all respects whatever." Thus the Congress, utilizing the discretion allowed by the framers, adopted a policy of equal status for all newly admitted states. With the growth of states' rights advocacy during the antebellum period, the Supreme Court asserted, in Lessee of Pollard v. Hagan (1845), that the Constitution mandated admission of new states on the basis of equality. Congressional restrictions on the equality of states, even when those limitations have been
