Din-i Ilahi, or 'Religion of God,' was a syncretic belief system introduced by the Mughal emperor Akbar in the late 16th century. It aimed to merge the best elements of various religions, including Islam, Hinduism, and Christianity, to promote unity and tolerance within his empire. This initiative was part of Akbar's broader efforts to consolidate his power and foster a more inclusive society in a diverse land-based empire.
