The Martyrdom of Guru Tegh Bahadur Sahib honors the ninth Guru of Sikhism, who sacrificed his life in 1675 to protect religious freedom. He was executed by the Mughal emperor for standing against the forced conversion of Hindus, symbolizing courage, spiritual strength, and the defense of human rights. Sikhs commemorate the day with prayers, kirtan (devotional singing), and reflection on his legacy of selflessness and justice.
