Sikhism emerged in the Punjab during the Mughal period. Conflict between early Sikhs and the Muslim power centre at Delhi reached an early high point in 1606 when Guru Arjan Dev, the fifth guru of the Sikhs, was tortured and killed by the Mughal Emperor Jahangir. After his death, his son Guru Har Gobind moved in and turned the Sikhs into a warrior community. He was the first to defeat the Mughal empire in a battle at Sri Hargobindpur in Gurdaspur,[15] after which the Sikhs organised themselves militarily. Tegh Bahadur became the Guru in 1665 leading the community until 1675, when he was executed by the Mughal Emperor Aurangzeb.
