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. Insofar, the martyr is a relational figure of a society's boundary work that is produced by collective memory. 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.
Most martyrs are considered holy or are respected by their followers, becoming symbols of exceptional leadership and heroism in the face of difficult circumstances. Martyrs play significant roles in religions. Similarly, martyrs have had notable effects in secular life, including such figures as Socrates, among other political and cultural examples.
In its original meaning, the word martyr, meaning witness, was used in the secular sphere as well as in the New Testament of the Bible. The process of bearing witness was not intended to lead to the death of the witness, although it is known from ancient writers (e.g. Josephus) and from the New Testament that witnesses often died for their testimonies.
During the early Christian centuries, the term acquired the extended meaning of believers who are called to witness for their religious belief, and on account of this witness, endure suffering or death. The term, in this later sense, entered the English language as a loanword. The death of a martyr or the value attributed to it is called martyrdom.
The early Christians who first began to use the term martyr in its new sense saw Jesus as the first and greatest martyr, on account of his crucifixion. The early Christians appear to have seen Jesus as the archetypal martyr.
The word martyr is used in English to describe a wide variety of people. However, the following table presents a general outline of common features present in stereotypical martyrdoms.
In the Baháʼí Faith, martyrs are those who sacrifice their lives serving humanity in the name of God. However, Bahá'u'lláh, the founder of the Baháʼí Faith, discouraged the literal meaning of sacrificing one's life. Instead, he explained that martyrdom is devoting oneself to service to humanity.
Martyrdom was extensively promoted by the Tongmenghui and the Kuomintang party in modern China. Revolutionaries who died fighting against the Qing dynasty in the Xinhai Revolution and throughout the Republic of China period, furthering the cause of the revolution, were recognized as martyrs.
In Christianity, a martyr, in accordance with the meaning of the original Greek martys in the New Testament, is one who brings a testimony, usually written or verbal. In particular, the testimony is that of the Christian Gospel, or more generally, the Word of God. A Christian witness is a biblical witness whether or not death follows. However, over time many Christian testimonies were rejected, and the witnesses put to death, and the word martyr developed its present sense.
The concept of Jesus as a martyr has recently received greater attention. Analyses of the Gospel passion narratives have led many scholars to conclude that they are martyrdom accounts in terms of genre and style. Several scholars have also concluded that Paul the Apostle understood Jesus' death as a martyrdom. In light of such conclusions, some have argued that the Christians of the first few centuries would have interpreted the crucifixion of Jesus as a martyrdom.
In the context of church history, from the time of the , and Nero it developed that a martyr was one who was killed for maintaining a religious belief, knowing that this will almost certainly result in imminent death (though without intentionally seeking death). This definition of martyr is not specifically restricted to the Christian faith. Though Christianity recognizes certain Old Testament Jewish figures, like Abel and the Maccabees, as holy, and the New Testament mentions the imprisonment and beheading of John the Baptist, Jesus's possible cousin and his prophet and forerunner, the first Christian witness, after the establishment of the Christian faith (at Pentecost), to be killed for his testimony was Saint Stephen (whose name means "crown"), and those who suffer martyrdom are said to have been "crowned". From the time of Constantine, Christianity was decriminalized, and then, under Theodosius I, became the state religion, which greatly diminished persecution (although not for non-Nicene Christians). As some wondered how then they could most closely follow Christ there was a development of desert spirituality, desert monks, self-mortification, ascetics, (Paul the Hermit, St. Anthony), following Christ by separation from the world. This was a kind of white martyrdom, dying to oneself every day, as opposed to a red martyrdom, the giving of one's life in a violent death.
In Christianity, death in sectarian persecution can be viewed as martyrdom. For example, the Spanish Inquisition began in 1481. There were martyrs recognized on both sides of the schism between the Roman Catholic Church and the Church of England after 1534. Two hundred and eighty-eight Christians were martyred for their faith by public burning between 1553 and 1558 by the Roman Catholic Queen Mary I in England leading to the reversion to the Church of England under Queen Elizabeth I in 1559. "From hundreds to thousands" of Waldensians were martyred in the Massacre of Mérindol in 1545. Three hundred Roman Catholics were said to be martyred by the Church authorities in England in the sixteenth and seventeenth centuries.
Even more modern day accounts of martyrdom for Christ exist, depicted in books such as Jesus Freaks, though the numbers are disputed. There are claims that the numbers of Christians killed for their faith annually are greatly exaggerated, but the fact of ongoing Christian martyrdoms remains undisputed.
Despite the promotion of ahimsa (non-violence) within Sanatana Dharma, and there being no concept of martyrdom, there is the belief of righteous duty (dharma), where violence is used as a last resort to resolution after all other means have failed. Examples of this are found in the Mahabharata. Upon completion of their exile, the Pandavas were refused the return of their portion of the kingdom by their cousin Duruyodhana; and following which all means of peace talks by Krishna, Vidura and Sanjaya failed. During the great war which commenced, even Arjuna was brought down with doubts, e.g., attachment, sorrow, fear. This is where Krishna instructs Arjuna how to carry out his duty as a righteous warrior and fight.
Shahid originates from the Quranic Arabic word meaning "witness" and is also used to denote a martyr. Shahid occurs frequently in the Quran in the generic sense "witness", but only once in the sense "martyr, one who dies for his faith"; this latter sense acquires wider use in the hadiths. Islam views a martyr as a man or woman who dies while conducting jihad, whether on or off the battlefield (see greater jihad and lesser jihad). The concept of the martyr in Islam had been made prominent during the Islamic revolution (1978/79) in Iran and the subsequent Iran-Iraq war, so that the cult of the martyr had a lasting impact on the course of revolution and war.
Martyrdom in Judaism is one of the main examples of Kiddush Hashem, meaning "sanctification of God's name" through public dedication to Jewish practice. Religious martyrdom is considered one of the more significant contributions of Hellenistic Judaism to Western Civilization. 1 Maccabees and 2 Maccabees recount numerous martyrdoms suffered by Jews resisting Hellenizing (adoption of Greek ideas or customs of a Hellenistic civilization) by their Seleucid overlords, being executed for such crimes as observing the Sabbath, circumcising their boys or . According to W. H. C. Frend, "Judaism was itself a religion of martyrdom" and it was this "Jewish psychology of martyrdom" that inspired Christian martyrdom.
Martyrdom (called shahadat in Punjabi) is a fundamental concept in Sikhism and represents an important institution of the faith. The Sikh Gurus and the Sikhs that followed them are some of the greatest[peacock term] examples of martyrs who fought  against Mughal tyranny and oppression, upholding the fundamentals of Sikhism, where their lives were taken during non-violent protesting or in battles. Sikhs believe in Ibaadat se Shahadat (from love to martyrdom). Some famous Sikh martyrs include:
