The Martyrdom of Guru Tegh Bahadur Ji commemorates the ninth Sikh Guru, who was executed in 1675 in Delhi for defending the religious freedom of Kashmiri Pandits and refusing to convert to Islam under the Mughal emperor Aurangzeb. His sacrifice is revered as a profound act of courage and selflessness, made not to protect his own faith but the right of others to practice theirs freely. Sikhs mark this day with solemn prayers, kirtan, and reflection at gurdwaras, honoring his legacy as a defender of religious liberty and human dignity for people of all faiths.
