workers himself. Historians such as Edmund Morgan say this evidence suggests that racial attitudes were much more flexible in early 17th-century Virginia than they would later become. A 1625 census recorded 23 Africans in Virginia. In 1649 there were 300, and in 1690 there were 950. Over this period, legal distinctions between white indentured servants and "Negros" widened into lifelong and inheritable chattel-slavery for Africans and people of African descent. New England The 1677 work The Doings and Sufferings of the Christian Indians documents English colonial prisoners of war (not, in fact, opposing combatants, but imprisoned members of English-allied forces) being enslaved and sent to Caribbean destinations in the aftermath of Metacom's War. Captive indigenous opponents, including women and children, were also sold into slavery at a substantial profit, to be transported to West Indies colonies. African and Native American slaves made up a smaller part of the New England economy, which was based on yeoman farming and trades, than in the South, and a smaller fraction of the population, but they were present. Most were house servants, but some worked at farm labor. The Puritans codified slavery in 1641. The Massachusetts Bay royal colony passed the Body of Liberties, which prohibited slavery in some instances, but did allow three legal bases of slavery. Slaves could be held if they were captives of war, if they sold themselves into slavery, were purchased from elsewhere, or if they were sentenced to slavery by the governing authority. The Body of Liberties used the word "strangers" to refer to people bought and sold as slaves, as they were generally not native born English subjects. Colonists came to equate this term with Native Americans and Africans. The New Hampshire Assembly in 1714 passed "An Act To Prevent Disorders In The Night", prefiguring the development of sundown towns in the United States: Notices emphasizing and re-affirming the curfew were published in The New Hampshire Gazette in 1764 and 1771. New York and New Jersey The Dutch West India Company introduced slavery in 1625 with the importation of eleven enslaved blacks who worked as farmers, fur traders, and builders to New Amsterdam (present day New York City), capital of the nascent province of New Netherland. The Dutch colony expanded across the North River (Hudson River) to Bergen (in today's New Jersey). Later, slaves were also held privately by settlers in the area. Although enslaved, the Africans
