slaves and free blacks in Aiken County, South Carolina, in 1773; Petersburg, Virginia, in 1774; and Savannah, Georgia, in 1778, before the end of the Revolutionary War. Slavery was officially recognized as a serious offense in 1776 by the Philadelphia Yearly Meeting. The Yearly Meeting had been against slavery since the 1750s. East Indian slaves In the early 21st century, new research has revealed that small numbers of East Indians were brought to the colonies as enslaved laborers, during the period when both India and the colonies were under British control. As an example, an ad in the Virginia Gazette of Aug. 4, 1768, describes one young "East Indian" as "a well made fellow, about 5 feet 4 inches high" who had "a thin visage, a very sly look, and a remarkable set of fine white teeth." Another slave is identified as "an East India negro man" who speaks French and English. Most of the Indian slaves were already converted to Christianity, were fluent in English, and took western names. Their original names and homes are not known. Their descendants have mostly merged with the African-American community, which also incorporated European ancestors. Today, descendants of such East Indian slaves may have a small percent of DNA from Asian ancestors but it likely falls below the detectable levels for today's DNA tests, as most of the generations since would have been primarily of ethnic African and European ancestry. Beginning of the anti-slavery movement African and African-American slaves expressed their opposition to slavery through armed uprisings such as the Stono Rebellion (1739) in South Carolina. More typically, they resisted through work slowdowns, tool-breaking, and running away, either for short periods or permanently. Until the Revolutionary era, almost no white American colonists spoke out against slavery. Even the Quakers generally tolerated slaveholding (and slave-trading) until the mid-18th century, although they emerged as vocal opponents of slavery in the Revolutionary era. During the Great Awakening, Baptist and Methodist preachers in the South originally urged planters to free their slaves. In the nineteenth century, they more often urged better treatment of slaves. Further events Late 18th and 19th century During and following the Revolution, the northern states all abolished slavery, with New Jersey acting last in 1804. Some of these state jurisdictions enacted the first abolition laws in the entire New World. In states that passed gradual abolition laws, such as New York and New
