`Abdu'l-Bahá, the son of the founder of the religion, wrote a series of letters, or tablets, to the followers of the religion in the United States in 1916-1917; these letters were compiled together in the book titled Tablets of the Divine Plan.
Following the release of these tablets and then `Abdu'l-Bahá's death in 1921, a few Bahá'ís began moving to or at least visiting Latin America.
