Blackmail is a criminal act of coercion using a threat.
As a criminal offense, blackmail is defined in various ways in common law jurisdictions. In the United States, blackmail is generally defined as a crime of information, involving a threat to do something that would cause a person to suffer embarrassment or financial loss. By contrast, in the Commonwealth its definition is wider: for example, the laws of England and Wales and Northern Ireland state that:
Theft (from Old English þeofð, cognate to thief) is the act of taking another person's property or services without that person's permission or consent with the intent to deprive the rightful owner of it. The word theft is also used as a synonym or informal shorthand term for some crimes against property, such as larceny, robbery[heist], embezzlement, extortion, blackmail, or receiving stolen property. In some jurisdictions, theft is considered to be synonymous with larceny, while in others, theft is defined more narrowly. A person who engages in theft is known as a thief (pl. thieves).
Theft is the name of a statutory offence in California, Canada, England and Wales, Hong Kong, Northern Ireland, the Republic of Ireland, and the Australian states of South Australia and Victoria.
Coercion involves compelling a party to act in an involuntary manner through the use of threats, including threats to use force against that party. It involves a set of forceful actions which violate the free will of an individual in order to induce a desired response. These actions may include extortion, blackmail, or even torture and sexual assault. Common-law systems codify the act of violating a law while under coercion as a duress crime.
Coercion used as leverage may force victims to act in a way contrary to their own interests. Coercion can involve not only the infliction of bodily harm, but also psychological abuse (the latter intended to enhance the perceived credibility of the threat). The threat of further harm may also lead to the acquiescence of the person being coerced. The concepts of coercion and persuasion are similar, but various factors distinguish the two. These include the intent, the willingness to cause harm, the result of the interaction, and the options available to the coerced party.

In psychology, manipulation is defined as an action designed to influence or control another person, usually in an underhanded or subtle manner which facilitates one's personal aims. Methods someone may use to manipulate another person may include seduction, suggestion, coercion, and blackmail. Manipulation is generally considered a dishonest form of social influence as it is used at the expense of others. Humans are inherently capable of manipulative and deceptive behavior, with the main differences being that of specific personality characteristics or disorders.
