The Ibadat Khana was a meeting house built in 1575 CE by the Mughal Emperor Akbar at his palace in Fatehpur Sikri to gather religious leaders of many faiths in discussion. He built it originally as a debating house open only to Sunni Muslims, but following a series of petty squabbles which turned ugly, Akbar encouraged Hindus, Roman Catholics and even atheists to participate. Religious leaders and philosophers from around this diverse empire, as well as those passing through, were invited to Akbar's Thursday evening discussions.
