The day marks the death of Guru Arjan in Mughal custody at Lahore, an execution the emperor Jahangir recorded ordering in his own memoirs. No account of when Sikhs first kept the anniversary has been identified, and its place on 16 June comes from the Nanakshahi calendar rather than from any founding act.
The order, in the emperor's own hand
Jahangir's account of what he did next is unusually direct. He ordered the man produced, handed his houses and children to Murtaza Khan, and "having confiscated his property commanded that he should be put to death".
The passage gives him no religion of his own. It calls him "a Hindu named Arjun" and notes that "They called him Guru", and it records a confiscation rather than a fine.
