Abstract
The present text deals with the application of Rodney Stark's model "Why religious groups succeed or fail" on the Baha'ism (Baha'i faith) in the USA. Baha'ism is a relatively young and ambitious religious movement originally from Iran whose goal is to spread to all countries in the world and to establish a so co-called "world Bahá'i civilization." The central role was assigned to the United States of America, where is located the biggest western Baha'i community.
Based on Stark's model, we can say that the Baha'ism (it meets only two criteria of ten) is an unsuccessful religious movement, which is consistent with a low number of adherents according to the US censuses.
