Curiously enough, slavery continued to exist, until a comparatively recent period, in many of the States that had early declared it abolished. The States formed out of the territory "Northwest of the River Ohio" cannot be said to have ever been slave States. The sixth section of the Ordinance of 1787 prohibited slavery forever therein. The slaves reported in such States were only there by tolerance. They were free of right. The Constitution of Illinois, as we shall presently see, did not at first abolish slavery; only prohibited the introduction of slaves. The rebellion of the thirteen colonies in 1776 and the war for independence did not grow out of slavery; that war was waged neither to perpetuate nor to abolish it. The Puritan and Cavalier, the opponents and the advocates of slavery and the slave trade, alike, fought for independence, and, when successful, united in the purpose to foster and build up an American Republic, based on the sovereignty of individual citizenship, but ignoring the natural rights of the enslaved negro. The following table, compiled from the United States Census Reports, may be of interest. It shows the number of slaves reported in each State and Territory of the United States at each Federal census.( 9) _North_ 1790 1800 1810 1820 1830 1840 1850 1860 Cal. . . . . . . . . . . . . . . . . . . . . . . . . . . .
