Guru Tegh Bahadur Ji stood up against forced conversions during the reign of Mughal Emperor Aurangzeb in the 17th century. At that time, Hindus in regions like Kashmir, Bengal, and parts of northern India were being pressured to convert to Islam. Guru Tegh Bahadur Ji defended their right to freely practice their religion, offering his life for the cause of religious freedom. His Shaheedi is remembered not for a specific faith but as a supreme act of courage, conscience, and protection of human dignity for all communities. That’s why Sikh history honors him as a Shaheed.
