Sulh-i-kul was never merely a private disposition of Akbar's; it was legislated into the ordinary business of governing a vast, religiously mixed empire. The abolition of the jizya, the tax non-Muslims paid under classical Islamic law, in 1564 was its earliest large-scale expression, removing a fiscal marker of Hindu subordination from an empire in which Hindus formed the overwhelming majority of subjects.
Hindu Rajput nobles were brought into the highest ranks of Mughal administration and the military, some through marriage alliances with the imperial family, and Akbar extended patronage to Hindu temples, Jain pilgrimage sites and Zoroastrian communities alongside the mosques and Sufi shrines a Muslim emperor would be expected to support. None of this required Akbar to abandon Islam himself, and he continued, for most of his reign, to be recorded observing Islamic practice; sulh-i-kul asked the state to hold peace among faiths, not that the emperor personally renounce his own.
