Emancipation today refers to the point at which a child is free from parental control. This can occur in several different circumstances: parents may choose to voluntarily surrender their rights to the care, custody and earnings of their minor child and cease to perform their parental duties; they may imply consent by allowing a minor child to leave her parents' home and become entirely self-supporting; a minor child becomes emancipated upon marriage or entering the military. The term was also used when slavery was legal to describe the condition of a former slave who had bought or been given freedom from his or her master. When Abraham Lincoln outlawed slavery he did so in a law called the "Emancipation Proclamation".
