Oppression is malicious or unjust treatment of, or exercise of power over, a group of individuals, often in the form of governmental authority or cultural opprobrium. It is related to regimentation, class, society, and punishment. Oppression may be overt or covert, depending on how it is practiced. Oppression refers to discrimination when the injustice does not target and may not directly afflict everyone in society, but instead targets or disproportionately impacts specific groups of people.

Injustice is a quality relating to unfairness or undeserved outcomes. The term may be applied in reference to a particular event or situation, or to a larger status quo. In Western philosophy and jurisprudence, injustice is very commonly—but not always—defined as either the absence or the opposite of justice.
