received judicial sanction, and the time was at hand when the question of freedom or slavery in the western territory was to be determined. Between March and December, 1853, the discovery was made that the Act of 1850 organizing the Territories of New Mexico and Utah had superseded the Compromise of 1820; that a principle had been recognized applicable to all the Territories; that all were open to settlement on equal terms to slaveholders and non-slaveholders; that the subject of slavery should be removed from Congress to the people of the Territories; and that they should decide, either when a territorial legislature was organized or at the time of the adoption of a constitution preparatory to statehood, whether or not slavery should be authorized. These ideas found expression in various newspapers during the month of December, 1853. Though the authorship of the new theory is still a matter of dispute, it is well known that Stephen A. Douglas became its chief sponsor and champion. The real motives and intentions of Douglas himself and of many of his supporters will always remain obscure and uncertain. But no uncertainty attaches to the motives of Senator Atchison and the leaders of the Calhoun section of the Democratic party. For ten years at least they had been laboring to get rid of the Missouri Compromise. Their motive was to defend slavery and especially to forestall a successful movement for emancipation in the State of Missouri. From early in January, 1854, until late in May, Douglas's Nebraska bill held the attention of Congress and of the entire country. At first the measure simply assumed that the Missouri Compromise had been superseded by the Act of 1850. Later the bill was amended in such a way as to repeal distinctly that time-honored act. At first the plan was to organize Nebraska as a single Territory extending from Texas to Canada. Later it was proposed to organize separate Territories, one west of Missouri under the name of Kansas, the other west of Iowa under the name of Nebraska. Opposition came from Free-soilers, from Northern Whigs and a few Whigs from the South, and from a large proportion of Northern Democrats. The repeal of the Missouri Compromise came like a thunderbolt out of a clear sky to the people of the North. For a time Douglas was the most unpopular of political leaders and was apparently repudiated by his party. The first name designating the opponents of the Douglas bill was "Anti-Nebraska men," for which the name Republican was gradually substituted and in 1856 became the accepted title of the party.
