In the Dutch Republic slavery was not permitted on its soil in Western Europe. Enslaved people obtained their freedom by setting foot on Dutch soil. In 1776, the scope of this free soil principle was limited by a statute of the States General. From this moment onwards only slaves who remained in the Republic for longer than six months would automatically become free. In the literature, it was hitherto assumed that with the establishment of this statute the first debates about the scope of the free soil principle were initiated. This article demonstrates that this assumption is false. Previously, two court cases from 1735 and 1736, between two enslaved men from Curaçao and their masters, had already given rise to discussion. During these court cases, lawyers and judges elaborately debated the boundaries of the free soil principle. Did every enslaved person automatically obtain their freedom, or was, for instance, the permission of the master required to travel to the Dutch Republic? The two court cases give insight into what contemporaries thought about the free soil principle, thus shedding new light on the States General’s statute of 1776.
