June 1912: While in New York, ‘Abdu’l-Baha declares His own station as the ‘Center of the Covenant’ – New York becomes the City of the Covenant

The next day, June 19th, was an historic day for the Bahá'ís of New York, for on that day 'Abdu'l-Bahá named their city the City of the Covenant. He spoke in their gathering of the Tablet of the Branch, revealed by Bahá'u'lláh in Adrianople, and declared His own station: the Centre of the Covenant. In New York He had made this emphatic, authoritative statement in public, and therefore New York was invested with that distinction. On the same day He received the manuscript of The Brilliant Proof which He greatly admired, and arranged for its translation and publication in the United States.
