And out of that hopeless attempt has come nearly all that we call human history-money, poverty, ambition, war, prostitution, classes, empires, slavery-the long terrible story of man trying to find something other than God which will make him happy.- C.S. Lewis ,Mere Christianity

Definition:
According to Cambridge dictionary slavery is the activity of legally owning other people who are forced to work for or obey you: or the condition of being legally owned by someone else and forced to work for or obey them:

Anti-Slavery International: A person today is considered enslaved if they are forced to work against their will; are owned or controlled by an exploiter or employer; have limited freedom of movement; or are dehumanized, treated as a commodity or bought and sold as property.

Article 14 provides equality before law. It not only commands the state not to deny equality before law but also commands not to deny equal protection before law. Through which it is the duty of every state to protect the rights of the individual through administering laws for the state. Article 19(1) of our Indian Constitution provides every person, freedom of speech and expression. This is regarded as one of the fundamental right as provided by the constitution. Article 21 is as follows, No person shall be deprived of his life or personal liberty except according to procedure established by law.

This is the most fundamental of human rights. It also recognizes the sanctity of human life. Article 23-Prohibition of traffic in human beings and forced labour. Traffic in human beings and beggar and other similar forms of forced labour are prohibited and any contravention of this provision shall be an offence punishable in accordance with law.

Slavery, condition in which one human being was owned by another. A slave was considered by law as property, or chattel, and was deprived of most of the rights ordinarily held by free persons. There is no consensus on what a slave was or on how the institution of slavery should be defined.

Nevertheless, there is general agreement among historians, anthropologists, economists, sociologists, and others who study slavery that most of the following characteristics should be present in order to term a person a slave. The slave was a species of property; thus, he belonged to someone else. In some societys slaves were considered movable property, in others immovable property, like real estate. They were objects of the law, not its subjects. Thus, like an ox or an ax, the slave was not ordinarily held responsible for what he did.
