The Apostles of Baháʼu'lláh were nineteen prominent early followers of Baháʼu'lláh, the founder of the Baháʼí Faith. The apostles were designated as such by Shoghi Effendi, head of the religion in the earlier half of the 20th century, and the list was included in The Baháʼí World, Vol. III (pp. 80–81). These individuals played a vital role in the development of the Baháʼí Faith, consolidating its adherents and bringing its teachings around the world.
