Guru Arjan Dev Ji's martyrdom, observed as Shaheedi Diwas, commemorates the fifth Sikh Guru's torture and death in Lahore in 1606 under the orders of Mughal Emperor Jahangir. The Guru was arrested after refusing to remove passages from the Adi Granth deemed offensive and declining to pay a fine, with court factions and his own brother Prithi Chand conspiring against him . He endured five days of severe torture at Lahore Fort—including being seated on hot iron plates and having boiling water poured over him while steadfastly refusing to compromise his faith . He breathed his last on May 30, 1606, becoming the first Sikh Guru to embrace martyrdom . His sacrifice profoundly shaped Sikh consciousness, inspiring his son Guru Hargobind to adopt the doctrine of Miri-Piri and establish the Akal Takht, marking a turning point toward armed resistance against oppression .
