Portrait of `Abdu'l-Bahá.
While `Abdu'l-Bahá was still a prisoner of the Ottomans the first Bahá'í pilgrims from the western world arrived in Acre in 1898. After His release in 1908, `Abdu'l-Bahá set out on a series of journeys which, in 1911-1913, took Him to Europe and America. There He proclaimed Bahá'u'lláh's message of unity and social justice to church congregations, peace societies, the members of trade unions, university faculties, journalists, government officials, and many public audiences.
`Abdu'l-Bahá passed away in 1921, having consolidated the foundations of the Bahá'í Faith and greatly expanded its reach. The northern rooms of the Shrine of the Báb, where He is interred, are a place of pilgrimage for Bahá'ís visiting the World Centre of their Faith.
