The opportuneness of these settlements is shown by a number of conditions. The contest between negro slavery and white servitude had been settled in favor of slavery. The Tuscorora Indians, the implacable enemies of negroes, were driven out of the colony in 1772. The moral evils of slavery had not appeared.[7] The English government in 1663, by chartering the Royal African Company to engage in the slave trade, became interested in the development of slavery, and, thereafter, discouraged the importation of indented servants into the colonies in order that this company might have a larger market for slaves.[8] It was early recognized that the industrial life of the colonies offered practically no place to the white servant at the expiration of his indenture. He was not financially able to purchase land and white servants or negro slaves, necessary to farming, nor could he find employment in the villages and small towns, because they were not sufficiently industrialized at this time to offer such opportunities. These influences produced a rapid increase in the slave population of the colonies. In 1709, Rev. John Adams, a missionary, reported 800 slaves in North Carolina.[9] In 1717, there were 1,100 slaves out of a taxable population of 2,000.[10] Governor Burrington stated that there were 6,000 in 1730.[11] The census of 1754 showed a population of 9,128 slaves. In 1756, there were 10,800 negro taxables and as the ratio of taxable negroes (those of the age of twelve and above) to the total negro population was about ten to eighteen, there must have been, at this time, approximately 20,000 slaves in the colony. There were 39,000 in 1767.[12]
