Historians offer more than one explanation for why Jahangir moved against Guru Arjan specifically in 1606, and the accounts are not mutually exclusive: alongside the general Mughal unease at the growing institutional strength and following of the Sikh community this entry's first article describes, Jahangir's own memoirs record his anger at reports that Guru Arjan had blessed or otherwise supported Khusrau Mirza, the emperor's own son, who led an unsuccessful rebellion against his father that same year, a specific and immediate political charge layered on top of the broader, longer-building suspicion of the Guru's authority and resources.
Whether the Khusrau connection was the decisive trigger, a convenient additional justification for an arrest Jahangir was already inclined to make, or a genuinely central cause in its own right remains debated among historians working from the available Mughal and Sikh sources, which do not fully agree on the sequence and weight of events, but the political rebellion angle is a documented part of the historical record around the martyrdom that sits alongside, rather than replacing, the institutional and religious tensions between the growing Sikh community and the Mughal state that the broader Sikh historical tradition emphasises.
