'Abdu'l-Bahá
(The Center of the Covenant)
23 May, 1844 - 28 November, 1921
[Bahá'u'lláh's] eldest son, 'Abbas Effendi, known as 'Abdu'l-Bahá (the Servant of Bahá), appointed by Him as His lawful successor and the authorized Interpreter of His teachings, Who since early childhood had been closely associated with His Father, and shared His exile and tribulations, remained a prisoner until 1908, when, as a result of the Young Turk Revolution, He was released from His confinement. Establishing His residence in Haifa, He embarked soon after on His three-year journey to Egypt, Europe, and North America in the course of which He expounded before vast audiences the teachings of His Father and predicted the approach of that catastrophe that was soon to befall mankind. He returned to His home on the eve of the first World War, in the course of which He was exposed to constant danger, until the liberation of Palestine by the forces under the command of General Allenby, who extended the utmost consideration to Him and to the small band of His fellow-exiles in 'Akká and Haifa. In 1921 He passed away, and was buried in a vault in the mausoleum erected on Mount Carmel, at the express instruction of Bahá'u'lláh, for the remains of the Báb, which had previously been transferred from Tabríz to the Holy Land after having been preserved and concealed for no less than sixty years.
