Akbar, the Mughal emperor Humayun's son and heir from his Sindhi queen Hameeda Banu Begum, had a broad vision of Indian and Islamic traditions. One of Emperor Akbar's most unusual ideas regarding religion was Din-i-Ilahi (Faith of God), which was an eclectic mix of Islam, Zoroastrianism, Hinduism, Jainism and Christianity. It was proclaimed the state religion until his death. These actions, however, met with stiff opposition from the Muslim clergy, especially the Sufi Shaykh Alf Sani Ahmad Sirhindi. Akbar's abolition of poll-tax on non-Muslims, acceptance of ideas from other religious philosophies, toleration of public worship by all religions and his interest in other faiths showed an attitude of considerable religious tolerance, which, in the minds of his orthodox Muslim opponents, were tantamount to apostasy. Akbar's imperial expansion acquired many Hindu states, many of whom were Hindu Rajputs, through vassalage. The Rajput vassals maintained semi-autonomy in running religious affairs. Many Hindu Rajput vassals built monumental Hindu temples during the period, such as Chaturbhuj Temple and Lakshmi Temple at Orchha, by the Mughal vassal, the Hindu Rajput Orchha State.
