"freedom dues". Africans could legally raise crops and cattle to purchase their freedom. They raised families, married other Africans and sometimes intermarried with Native Americans or European settlers. By the 1640s and 1650s, several African families owned farms around Jamestown and some became wealthy by colonial standards and purchased indentured servants of their own. In 1640, the Virginia General Court recorded the earliest documentation of lifetime slavery when they sentenced John Punch, a Negro, to lifetime servitude under his master Hugh Gwyn for running away. In the Spanish Florida some Spanish married or had unions with Pensacola, Creek or African women, both slave and free, and their descendants created a mixed-race population of mestizos and mulattos. The Spanish encouraged slaves from the colony of Georgia to come to Florida as a refuge, promising freedom in exchange for conversion to Catholicism. King Charles II issued a royal proclamation freeing all slaves who fled to Spanish Florida and accepted conversion and baptism. Most went to the area around St. Augustine, but escaped slaves also reached Pensacola. St. Augustine had mustered an all-Black militia unit defending Spanish Florida as early as 1683. One of the Dutch African arrivals, Anthony Johnson, would later own one of the first Black "slaves", John Casor, resulting from the court ruling of a civil case. The popular conception of a race-based slave system did not fully develop until the 18th century. The Dutch West India Company introduced slavery in 1625 with the importation of eleven Black slaves into New Amsterdam (present-day New York City). All the colony's slaves, however, were freed upon its surrender to the English. Massachusetts was the first English colony to legally recognize slavery in 1641. In 1662, Virginia passed a law that children of enslaved women took the status of the mother, rather than that of the father, as under common law. This legal principle was called partus sequitur ventrum. By an act of 1699, the colony ordered all free Blacks deported, virtually defining as slaves all people of African descent who remained in the colony. In 1670, the colonial assembly passed a law prohibiting free and baptized Blacks (and Indians) from purchasing Christians (in this act meaning White Europeans) but allowing them to buy people "of their owne nation". In the Spanish Louisiana although there was no movement toward abolition of the African slave trade, Spanish rule introduced a new law called coartación,
