At present there are Bahai congregations in sixteen of the United States, in Canada, Hawaii, South Africa, England, Germany and Russia, as well as in India and Burmah. The future of its propaganda in Christendom lacks promise. Yet its measure of success makes it desirable to examine its claims and the facts regarding them. Fortunately besides the older Babi books, there is an abundance of Bahai literature. There are (1) Treatises of Baha Ullah, (2) Tablets (Letters) and Addresses of Abdul Baha, (3) Persian Narratives, (4) Evidential books and tracts by its propagators, (5) Narratives of pilgrimages to Acca. From an independent point of view, little has been written. Nearly all of the many articles which have appeared in periodical literature have been from the pens of Bahais, though often not so ostensibly. Prof. E. G. Browne of Cambridge University, England, has translated and edited important Babi-Bahai works. His Introductions, Notes and Appendices to these books are storehouses of erudition and enable the reader to correct the biased information of the text. They pertain for the most part to the Babi period. So do the able contributions of Mr. A. L. M. Nicolas, the Consul of France, with whom, as my neighbour at Tabriz, I have had the pleasure of valuable conversations on this subject on which he is such an authority. I have had as sources of information also a manuscript "Life of Baha Ullah" by Mohammed Javad Kasvini, the "Kitab-ul-Akdas," Most Holy Book, translated by Dr. I. G. Kheiralla, in manuscript, and various unpublished letters and documents. Besides all this, I have been in personal contact with Bahais in Persia for a generation. My language teachers were Bahais, one of them a convert to Christianity. I have found their journal, the _Star of the West_, a prolific source of information. I may claim not to be of the class referred to by Abdul Baha when he says, "Baha Ullah will be assailed by those who are not informed of his principles." After sketching, in brief, the history of Bahaism I will examine its religious, moral, political and social doctrine and life. In doing this I shall quote for the most part from the words of the "Revelation" and its adherents, in order to insure fairness and justice. In the course of the investigation, the history and character of the founders will be considered. Finally I shall describe its propaganda in the Occident. Bahais declare that Babism is abrogated and superseded. In reality it is dead and I do not treat of it, except as it throws light on the history or doctrines of Bahaism. To all intents and purposes, the Bab is as much an obsolete prophet as Mani or Babak.
