Two hours and eleven minutes after sunset Siyyid `Alí-Muhammad made His declaration to Mullá Husayn-i-Bushrú'í in the upper room of His House. [DB52-65]

“I am, I am, I am, the promised One! I am the One whose name you have for a thousand years invoked, at whose mention you have risen, whose advent you have longed to witness, and the hour of whose Revelation you have prayed God to hasten. Verily I say, it is incumbent upon the peoples of both the East and the West to obey My word and to pledge allegiance to My person.” [DB315-316]

The garden was located in a large agricultural area immediately north of the walls of the city of Baghdad, about 450 metres (1,480 ft) from the city's northern Mu'azzam gate. Located on the eastern bank of the Tigris River in what is now the Bab al-Mu'azzam neighbourhood of Baghdad's Rusafa District, it was directly opposite the district in which Bahá'u'lláh lived during his stay in the city, on the river's western bank.

Extract from a Tablet of Baha'u'llah-Khadimu'llah. (Edited provisional translation below)

"On the first day that the Ancient Beauty occupied the Most Great Throne in a Garden which hath been designated Ridván, the Tongue of Grandeur uttered three blessed verses.
[1] The first of them was that in this Manifestation the use of the sword in holy war is put aside.
[2] Secondly, prior to the completion of a millennium any theophanological claim put forward by any person must be considered baseless. In this respect the year should be considered a complete year.
[3] Thirdly, the True One, exalted be His Glory, at that time manifested all the Divine Names upon all things.
“Verily, all created things were immersed in the sea of purification when, on that first day of Ridván, We shed upon the whole of creation the splendours of Our most excellent Names and Our most exalted Attributes”. [Kitab-i-Aqdas para75 p47]

And the following choice verse was subsequently revealed but has been ordained to be of the same rank as the preceding three; namely, whatever personal designations are mentioned before the Face, whether living or dead, such have thereby attained the Presence of God by virtue of being mentioned by the King of Pre-Existence.

1. He forbade the use of the sword.
2. He stated that no other Manifestations will appear before one thousand years. This was later reiterated in the Kitáb-i-Badí‘ and in The Kitáb-i-Aqdas.
3. He stated that, as from that moment, all the names and attributes of God were manifested within all created things, implying the advent of a new Day. [RB1:278–80]

During the 12 days in the Ridván Garden Bahá'u'lláh confided to ‘Abdu'l-Bahá that He was ‘Him Whom God shall make manifest'. [CH82]

Given that the Balfour Declaration was not a unilateral document on behalf of the British but rather something which had been agreed upon privately by allied diplomats before it was issued, it is viewed as the beginning of a legal process, which involved the San Remo conference of 1920 where the Declaration was officially adopted by the allied powers and latter, the creation of the British Mandate for Palestine in 1922.

The implementation of the Declaration was not without its failings. It provided for the safeguarding of the rights of the residents of Palestine saying ‘nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine’. In the run up to WWII that the British wanted to placate the Arab leadership in the Mandate. They issued a White Paper limiting Jewish immigration to the Mandate to fifteen thousand every year for five years, ultimately refusing entry to thousands of Jewish refugees from Europe, many of whom would tragically die in the Holocaust.

"His letters to Bahá’í institutions and to Bahá’ís in general began almost at once, and many will be found in Bahá’í Administration, beginning January 21, 1922. Early or late, his communications were not merely writings, they were the dynamic that moved the Bahá’í world. These letters in effect built the Administrative Order, its most vital features being found there. They taught the Bahá’í Assemblies how to be, how to consult, what their duties were. The book also contains the Declaration of Trust and By-Laws drawn up by the international lawyer Mountfort Mills, carefully reviewed by Shoghi Effendi, and adopted in 1926 by the National Spiritual Assembly of the United States and Canada, at this time under one jurisdiction. (Khan, back in America by then. Shoghi Effendi wished all National Spiritual Assemblies to adopt, with necessary local adaptations, this Declaration of Trust and ByLaws, which set forth the character and objectives of Bahá’í communities worldwide."
