Answer 2

A "free Negro" (or "free black"), was the term used prior to the abolition of slavery in the United States to describe African Americans who were not slaves. Almost all African Americans came to the United States as slaves, but from the onset of American slavery, slaveholders freed both male and female slaves for various reasons. Sometimes the heirs of deceased slave owners did not want slaves. In other instances, slaves were freed as a reward for good service, and others still were able to pay slaveholders money in exchange for their freedom. Free blacks during the antebellum era—which began with the formation of the Union (1781) and ended with the outbreak of the Civil War (1860)—were very outspoken about the injustice of slavery.
