A martyr (Greek: μάρτυς, mártys, "witness"; stem μάρτυρ-, mártyr-) is someone who suffers persecution and death for advocating, renouncing, refusing to renounce, or refusing to advocate a religious belief or cause as demanded by an external party. In the martyrdom narrative of the remembering community, this refusal to comply with the presented demands results in the punishment or execution of an actor by an alleged oppressor. Accordingly, the status of the 'martyr' can be considered a posthumous title as a reward for those who are considered worthy of the concept of martyrdom by the living, regardless of any attempts by the deceased to control how they will be remembered in advance. Originally applied only to those who suffered for their religious beliefs, the term has come to be used in connection with people killed for a political cause.
