Final answer:
Guru Tegh Bahadur was a leader of Sikhism, and his execution by the Mughal Emperor Aurangzeb was a significant event in the history of Sikh-Mughal relations.
Step-by-step explanation:
Guru Tegh Bahadur was a leader of Sikhism. This monotheistic faith, which originated in the Punjab region of northwestern India during the 15th century, is known for combining elements of Hinduism and Islam. Guru Tegh Bahadur was the ninth Sikh Guru, and his execution by the Mughal Emperor Aurangzeb marked a significant point of conflict between the Mughal Empire and the Sikhs. Aurangzeb's policies toward non-Muslims, including severe persecution and the imposition of additional taxes, created substantial resistance among the Sikhs and further entrenched their identity as a distinct religious community.
