A martyr is an individual who faces persecution or death in defense of, rejection of, or defiance against a belief or cause, often religious, as shaped by external pressures. Rooted in Christian tradition, the term has broadened to include political and cultural contexts, highlighting the role of collective memory in defining such figures.
Authors like John Greenleaf Whittier praised the endurance of martyrs, while J. C. McFeeters highlighted their spiritual example, and ʻAbdu'l-Bahá acknowledged their spirit of self-sacrifice. These differing viewpoints emphasize the martyr's dual function as both a symbol of defiance and a force for shaping communal identity, evolving from a religious icon to a wider representation of sacrifice in the human struggle.
