The Bahá'í Faith in Brazil started in 1919 with Bahá'ís first visiting the country that year, and the first Bahá'í Local Spiritual Assembly in Brazil was established in 1928. There followed a period of growth with the arrival of coordinated pioneers from the United States finding national Brazilian converts and in 1961 an independent national Bahá'í community was formed. During the 1992 Earth Summit, which was held in Brazil, the international and local Bahá'í community were given the responsibility for organizing a series of different programs, and since then the involvements of the Bahá'í community in the country have continued to multiply. The Association of Religion Data Archives (relying on World Christian Encyclopedia) estimated some 42211 Bahá'ís in 2005.
`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. The sixth of the tablets was the first to mention Latin American regions and was written on April 8, 1916, but was delayed in being presented in the United States until 1919—after the end of the First World War and the Spanish flu. The first actions on the part of Bahá'í community towards Latin America were that of a few individuals who made trips to Mexico and South America near or before this unveiling in 1919, including Mr. and Mrs. Frankland, and Roy C. Wilhelm, and Martha Root. Root's travels, probably the first Bahá'í to Brazil, began in the summer of 1919 - stopping first in Brazil, then Argentina and Uruguay before setting out to cross the Andes mountains into Chile in winter. The sixth tablet was translated and presented by Mirza Ahmad Sohrab on April 4, 1919, and published in Star of the West magazine on December 12, 1919.
