Baghdad – The House of Bahá'u'lláh in Baghdad, is a place ofBaháʼí pilgrimage. Its significance is that it is whereBahá'u'lláh lived in from 1853 to 1863 (except for two years). It is designated in theKitáb-i-Aqdas as a place of pilgrimage and is considered a holy place byBaháʼís.[1] During the 1920s the house was confiscated byShiah authorities, who were hostile to the Baháʼí Faith. The Council of theLeague of Nations upheld the Baháʼí's claim to the house, but it has not yet been returned to the Baháʼí community.[1][2]
