Some of the very earliest adherents of Christianity in the Middle East may have worn this hairstyle; there are descriptions of James the Just, first Bishop of Jerusalem, who is said to have worn them to his ankles. Pre-Columbian Aztec priests were described in Aztec codices (including the Durán Codex, the Codex Tudela and the Codex Mendoza) as wearing their hair untouched, allowing it to grow long and curl around itself. Bernal Diaz del Castillo records:here were priests with long robes of black cloth ... The hair of these priests was very long and so knotted that it could not be separated or disentangled, and most of them had their ears scarified, and their hair was clotted with blood. In Senegal, the Baye Fall, followers of the Mouride movement, a Sufi movement of Islam founded in 1887 AD by Shaykh Aamadu Bàmba Mbàkke, are famous for growing dreadlocks and wearing multi-colored gowns. Cheikh Ibra Fall, founder of the Baye Fall school of the Mouride Brotherhood, popularized the style by adding a mystic touch to it. Warriors among the Fulani, Wolof and Serer in Mauritania, and Mandinka in Mali were known for centuries to have worn cornrows when young and dreadlocks when old. Larry Wolff in his book Inventing Eastern Europe: The Map of Civilization on the Mind of Enlightenment mentions that in Poland, for about a thousand years, some people wore a knotted hairstyle similar to that of some Scythians.
The most recognizable of these groups are known as the Ngagpas of Tibet. For Buddhists of these particular sects and degrees of initiation, their locked hair is not only a symbol of their vows but an embodiment of the particular powers they are sworn to carry. 1.4.15 of the Hevajra Tantra states that the practitioner of particular ceremonies "should arrange his piled up hair" as part of the ceremonial protocol. Hinduism
The practice of Jaṭā (dreadlocks) is practiced in modern day Hinduism, most notably by Sadhus who follow Śiva. The Kapalikas, first commonly referenced in the 6th century CE, were known to wear Jaṭā as a form of deity imitation of the deva Bhairava-Śiva. Shiva is often depicted with dreadlocks. Rastafari
Rastafari movement dreadlocks are symbolic of the Lion of Judah which is sometimes centered on the Ethiopian flag. Rastafari hold that Haile Selassie is a direct descendant of King Solomon and the Queen of Sheba, through their son Menelik I. Their dreadlocks were inspired by the Nazarites of the Bible. Haile Selassie was crowned Emperor of Ethiopia in 1930. Many Jamaican Rastafarians claimed that Selassies coronation was evidence that he was the black messiah that they believed was prophesied in the Book of Revelation. Some street preachers such as Leonard Howell, Archibald Dunkley, Robert Hinds, and Joseph Hibbert began to claim that "Haile Selassie was the returned Jesus". During the Great Depression in the 1930s, the Rastafari message spread from  Kingston to the rest of Jamaica, especially among poor communities.
