The conditions above mentioned were undoubtedly the chief causes of the more rapid and pronounced development of negro slavery in the Southern colonies. And that more rapid and pronounced development directs us rather to the legislation of the Southern colonies than to that of the Northern, in following the legalization of the relation.

Partus
sequitur
ventrem.

Virginia naturally took the lead, and furnished the precedents for the others. The first question, both as to time and importance, which required legislative treatment, was the question of the status of the children of slaves. Where legalized marriage does not exist, the only certainty in respect to parentage is attained by regarding the mother. Rights and status in such a condition of society are, therefore, transmitted through the female line. Partus sequitur ventrem is the rule not only of the civil law, but of every system of law regulating the accidents of descent among people where the mingling of the sexes is not controlled by civilized marriage. Insuperable obstacles present themselves in the attempt to apply any other rule. It was no unusual or arbitrary enactment of the Virginia legislature which, in 1662, prescribed the rule that the status of the slave mother should determine that of her offspring. This rule was followed in all the colonies, and many of them enacted it into statute law.

Definitions of
the slave class.

So long as the slaves were few in number and were not Christians the necessity for legislation defining the slave class was not felt; but so soon as the slave-trade became more active, and slaves began to receive Christian baptism, the old customary test in regard to this matter, that of infidelity or heathenism, would no longer suffice. The colonists of that day were too conscientious to cut the knot of this difficulty by denying Christian baptism to any one seeking it. They considered it their prime duty to lead the heathen to the knowledge of Christ. It is evident that their consciences were greatly troubled over the question of the effect of Christian baptism upon the slave status. The colonial legislatures, the Home Government, and the Bishop of London were appealed to for counsel in the dilemma. The answers received from all of these were to the effect that the status of the slave was not changed by Christian baptism or conversion.

The test of the slave
status as fixed by
the Virginia statute.

The test of the slave status was then necessarily fixed by legislation. The Virginia statute declared all servants brought into the country by land or sea, who were not Christians in their native country at the time when they were purchased or procured, nor free in England or some other Christian country, to be slaves. Exception was made of Turks and Moors in amity with the King. This statute, taken together with the rule partus sequitur ventrem, which rule was re-enacted, became the test of the slave class. At the same time heavy penalties were attached to the marriage or cohabitation of white women with slaves.
