Challenge: Bahá'í Country

Your challenge, if you choose to accept it, is to create a nation where a majority of the poplation adheres to the Bahá'í Faith.
 
Only country I think would have a chance would be Samoa.

Upon independence, a very large number of Samoans convert to the faith of their Paramount Chief. This religion is passed down to their children. Also, Mormon missionaries stop targeting the island and begin focusing more on Tonga, and many of those who would convert to Mormonism instead become Bahais.

By the present time, 75% of Samoans are Bahais, and the House of Worship in Apia is one of the largest and most popular religious places in the world, a pilgrimage site rivaling Haifa as one of the holiest places in the Bahai world.
