In April 1863, shortly before his forced departure from Baghdad under continued Ottoman pressure to move him further from the Iranian border, Baha'u'llah spent twelve days in the Najibiyyih Garden on the outskirts of the city, a period Baha'is later renamed the Garden of Ridvan, meaning paradise. During this period, according to Baha'i accounts, Baha'u'llah announced to a small circle of family members and followers gathered with him that he was the promised figure the Bab's own writings had foretold, the one Baha'i teaching identifies as the fulfillment of eschatological expectation across multiple religious traditions.
The declaration came after years in which Baha'u'llah had lived in Baghdad as a leading, though not the sole, figure within the Babi exile community there, working to reunify and stabilize a movement that had been severely weakened by the earlier Iranian persecutions and by internal leadership disputes. His announcement at Ridvan marked a decisive shift, distinguishing the followers who accepted his claim, who would become the Baha'i community proper, from other Babis who did not.
Following the Ridvan declaration, Baha'u'llah and his family and followers were moved onward by Ottoman authorities, first to Constantinople and then to Adrianople, before his final, more settled exile and imprisonment at Akka, in present day Israel, where he would spend the rest of his life.
