The mainstream Sikh tradition recognised Guru Arjan as the fifth Guru, and Hargobind as the sixth Guru. Arjan, at age 18, became the fifth Guru in 1581 inheriting the title from his father. After his execution by the Muslim officials of the Mughal Empire, his son Hargobind became the sixth Guru. Guru Arjan Dev was made to sit on burning hot sheet/plate and hot sand was poured on him. After 5 days of torture, he was taken for bath in the river. He entered the river but was never seen again. His martyrdom is remembered as Shaheedi Divas of Guru Arjan.
