And early in Jahangir's reign, he is insecure about his hold on power. And remember, the Mughals are ruling from the same region where the Sikhs are having an increasingly growing following, not just from Hindus, but also from Muslims. Threatened by this growing following, Jahangir imprisons Guru Arjan and tortures Guru Arjan, trying to get him to renounce the faith, to convert to Islam. Guru Arjan refuses, despite many days of excruciating torture, being boiled alive. Eventually, he dies, and there's slightly varying accounts of how it happens. After his death, his son, who will be known as Guru Hargobind, comes to power. And Guru Hargobind, as legend has it, on direction from his father before he would die, tells him that the Sikhs need to protect themselves.
