The mulatto class in the colonies constituted an element through which transition of Negro servitude into slavery is apparent. As the mulattoes were looked upon as the result of an "abominable mixture" of the races and as representing a troublesome element in society, local laws and colonial statutes were gradually enacted to check and control them.[13] The statutes first aimed at serving as a deterrent upon the women, and hence arose the doctrine of _partus sequitur ventrem_, which imposed the mother's status upon the offspring. However, the first statute to this effect, the act of 1662 in Virginia, was largely enacted because of fornication of Englishmen and Negro women.[14] Statutes enunciating this doctrine were enacted in the other colonies as follows: Maryland, 1663; Massachusetts, 1698; Connecticut and New Jersey, 1704; Pennsylvania and New York, 1706; South Carolina, 1712; Rhode Island, 1728; and North Carolina, 1741.[15] Thus not only Negro mulattoes, that is, the offspring of white men and Negro women, were prevented from becoming servants, but those who were already either freemen or servants were gradually reduced to slavery. To check the growth of the mulatto class, particularly through the intermixture and intermarriage of Negro men and white women, a Virginia law in 1691 provided that the woman be fined, or sold into service for five years, or given five years of added time, and the mulatto be bound out for thirty years.[16] In Maryland, Pennsylvania, and North Carolina, similar laws were passed.[17] The mulatto, then, in one case was reduced from freeman and servant to slave, and in the other case made a servant for thirty or more years.[18] Thus the debasing of the status of the mulatto helped the transition to slavery.
