A human rights defender or human rights activist is a person who, individually or with others, acts to promote or protect human rights. They can be journalists, environmentalists, whistle-blowers, trade unionists, lawyers, teachers, housing campaigners, participants in direct action, or just individuals acting alone. [...]

The term human rights defender (HRD) became commonly used within the international human rights community after the UN General Assembly issued the Declaration on the Right and Responsibility of Individuals, Groups and Organs of Society to Promote and Protect Universally Recognised Human Rights and Fundamental Freedoms (A/RES/53/144, 1998), commonly known as the Declaration on Human Rights Defenders. Prior to this Declaration, activist, worker, or monitor were more common terms for people working to defend human rights. (Wikipedia)
