The Baháʼí Faith was formed in the late 19th-century Middle East by Baháʼu'lláh, and teaches that an official line of succession of leadership is part of a divine covenant that assures unity and prevents schism. There are no major schisms in the Baháʼí Faith, and attempts to form alternative leadership have either become extinct with time or have remained in extremely small numbers that are shunned by the majority. The largest extant sect is related to Mason Remey's claim to leadership in 1960, which has continued with two or three groups numbering at most 200 collectively, mostly in the United States.

The Baháʼí Faith is a religion founded in the 19th century that teaches the essential worth of all religions and the unity of all people. Established by Baháʼu'lláh, it initially developed in Iran and parts of the Middle East, where it has faced ongoing persecution since its inception. The religion is estimated to have 5 to 8 million adherents, known as Baháʼís, spread throughout most of the world's countries and territories.
