The Báb was martyred in Tabriz; and Bahá'u'lláh, exiled into Iraq in 1852, announced Himself in Baghdad. For the Persian government had decided that as long as He remained in Persia the peace of the country would be disturbed; therefore, He was exiled in the expectation that Persia would become quiet. His banishment, however, produced the opposite effect. New tumult arose, and the mention of His greatness and influence spread everywhere throughout the country. The proclamation of His manifestation and mission was made in Baghdad. He called His friends together there and spoke to them of God.
