QWho promulgated Din-i Ilahi?

The Din-i Ilahi (lit. "Religion of God") was a syncretic religion propounded by the Mughal emperor Akbar the Great in 1582 AD, intending to merge the best elements of the religions of his empire, and thereby reconcile the differences that divided his subjects. The elements were primarily drawn from Islam and Hinduism, but some others were also taken from Christianity, Jainism, Sikhism and Zoroastrianism.

Akbar promoted tolerance of other faiths. In fact, not only did he tolerate them, he encouraged debate on philosophical and religious issues. This led to the creation of the Ibadat Khana ("House of Worship") at Fatehpur Sikri in 1575. He had already repealed the jizya (tax on non-Muslims) in 1568. A religious experience while hunting in 1578 further increased his interest in the religious traditions of his empire

From the discussions held at the Ibadat Khana, Akbar concluded that no single religion could claim the monopoly of truth. This inspired him to create the Din-i Ilahi in 1582. Various pious Muslims, among them the Qadi of Bengal and the seminal Sufi personality Shaykh Ahmad Sirhindi, responded by declaring this to be blasphemy to Islam. According to a renowned historian Mubarak Ali, Din-i Ilahi is a name not present in Akbar's period. At that time it was called Tawhid-i-Ilahi ("divine monotheism"), as it is written by Abu Al Fazal, a court historian during the reign of Akbar. So it can be said that it was not a religion in proper sense or in comparison with the mainstream religions. As there was no compulsion in its acceptance, no reward, no punishment and no establishment of religious institutions. Furthermore, it can be said that it was a political system to bring unity in plurality rather than a religion.
