Bahá’u’lláh (1817–1892) was born in Iran as Mirza Husayn 'Ali and became the most influential of the early followers of the Báb. He acquired the title Bahá’u’lláh (Arabic for "the Glory of God") in 1848. In 1863 he announced a claim to be a messenger of God, the one whose coming was predicted by the Bible, the Qur’an, and by his forerunner, the Báb. Because of his claims, Bahá’u’lláh was repeatedly imprisoned and banished. In his forty-year ministry he produced over over 18,000 unique works, mostly letters and prayers, which defined the basics of his religion. He died in 1892 in Akka, a prison city in Palestine.
