Final answer:
Guru Arjan Dev Ji was made to sit on a red-hot iron plate under the rule of Mughal Emperor Jahangir. This incident is a notable event in Sikh history.
Step-by-step explanation:
Guru Arjan Dev Ji, the fifth Sikh Guru, was made to sit on a red-hot iron plate under the rule of Mughal Emperor Jahangir. Jahangir succeeded his father, Akbar, and ascended the throne in 1605. While he inherited a strong economy and a well-administered empire, he sought to outshine Akbar's achievements. Guru Arjan Dev Ji's martyrdom is one of the historic events that occurred during his reign, marking a significant turning point in Sikh history.
It is pertinent to note that Aurangzeb, another Mughal Emperor, is known to have executed Guru Tegh Bahadur, the ninth Sikh Guru, indicating the complex and often strained relations between the Mughal authorities and Sikh Gurus during this period. Guru Tegh Bahadur was a leader of the Sikh religion.
