Thus, at this crisis in the national history, there first distinctively appeared that aggressive, uncompromising party, afterwards to be known as the Slave Power--an association of men then forming a minority even in the South, but determined to carry its point at all hazards; men who were willing to sacrifice every consideration of the public good to the permanence of a system profitable to themselves, but which reduced human beings to the level of beasts. Against a party so resolute, antislavery opinion of the Patrick Henry variety could not prevail. Moreover, the distracted state of the country, the imperative necessity for union, made every other question seem secondary to the majority of patriotic statesmen. In the Constitutional Convention, the Slave Power, then chiefly represented by South Carolina and Georgia, by threatening to defeat the establishment of a stable government and by making the preservation of slavery a _sine qua non_ to the Union, obtained the concessions so big with future disaster. The struggle over this subject in the days of the formation of the government was the beginning of the "irrepressible conflict." The Slave Power had come into being as a distinct force, aiming to dominate the rest of the community in the interest of property in man. On the other hand, the opposition began to organize. Several abolition and manumission societies were formed. The oldest of these was that of Pennsylvania, which in 1787 chose Franklin for its president. A society was formed in New York in 1785 with John Jay as president and Alexander Hamilton as secretary; in Rhode Island in 1789, under the lead of Dr. Hopkins. In 1791, before the Connecticut society, Jonathan Edwards the younger maintained the doctrine of _immediate emancipation_. Similar associations were at work in New Jersey, Virginia, and Maryland. Antislavery men were thus uniting in their cause, but unfortunately they were, with rare exceptions, devoid of the earnestness which characterized their opponents. Their hostility to the system was a sentiment rather than a principle. It could hasten somewhat emancipation at the North; but it had no force to contend against the pecuniary interests which were daily binding tighter the bonds of the negro in the South. There, in the early years of the present century, the cotton-gin, which had been invented in 1793, gave an impetus to the production of cotton which nearly doubled the value of slaves. At the North the profits of the African trade which supplied this increased demand for negroes gave to the Slave Power allies almost as determined as themselves.
