Bahá'í Faith
While Baha'u'llah was in Baghdad, he had many problems, but he also made many friends. The government of Persia was unhappy that he seemed to be doing well in Baghdad, and so they asked the Ottoman Empire to move him further away from Persia. When he was about to leave, in 1863, he held a festival for 12 days on a small island in the Tigris river, which he called Ridvan, which means paradise. There he told some of his closest friends and family that he was the promised one of all of the major religions, and that eventually the whole world would know his message.
