Obeah is associated with both benign and malignant magic, charms, luck, and with mysticism in general. In some Caribbean nations, Obeah refers to folk religions of the African diaspora. In some cases, aspects of these folk religions have survived through syncretism with Christian symbolism and practice introduced by European colonials and slave owners. Casual observation may conclude that Christian symbolism is incorporated into Obeah worship, but in fact may represent clandestine worship and religious protest.
During slavery, Obeah was directed against the European slave masters. However, with the rise of Christianity, Obeah is considered a taboo, and the term has pejorative associations. 
In parts of the Caribbean where Obeah existed, slaves were taken from a variety of African nations with differing spiritual practices and religions. It is from these arrivals and their spiritualisms that Obeah originates. The theory of origin that is most accepted and is supported by the W. E. B. Du Bois Institute database traces obeah to the dibia or obia (Igbo: doctoring) traditions of the Igbo people. Specialists in Obia (also spelled Obea) were known as Ndi Obia (Igbo: Obia people) and practised the same activities as the obeah men and women of the Caribbean like predicting the future and manufacturing charms. Among the Igbo there were oracles known as ọbiạ which were said to be able to talk. Parts of the Caribbean where Obeah was most active imported a large number of its slaves from the Igbo dominated Bight of Biafra.
In another theory, the Efik language is the root of obeah where the word obeah comes from the Efik ubio meaning 'a bad omen'. The last theory of the origin of Obeah lies with the Ashanti who called their priests (or Obayifoɔ) practices Obayie(Akan: witchcraft). There is also evidence of Akan names among Obeah men of the Caribbean in the 17th and 18th centuries. The Akan origin of Obeah has been criticised by several writers with an Igbo origin thought to be more likely. However, in colonies where Bight of Biafra slaves were less represented and Akan were plenty (Suriname and Guyana), Obeah is thought to be more of a mixture of Akan beliefs.
Obeah came to mean any physical object, such as a talisman or charm, that was used for evil magical purposes. Obeah incorporated various beliefs from the religions of later migrants to the colonies it was present. Obeah also influenced other religions in the Caribbean, e.g. Christianity which incorporated some Obeah beliefs.
The term 'obeah' is first found in documents from the early 18th century, as in its connection to Nanny of the Maroons, but discussion of it becomes more frequent after it was made illegal in Jamaica after Tacky's War, in which an obeahman provided advice to the rebels.
In 1787 a letter to an English newspaper referred to "Obiu-women" interpreting the wishes of the dead at the funeral of a murdered slave in Jamaica: a footnote explained the term as meaning "Wise-women".
A continuing source of white anxiety related to Obeah was the belief that practitioners were skilled in using poisons, as mentioned in Matthew Lewis's Journal of a West India Proprietor. An anti-Obeah law passed in Barbados in 1818 specifically forbade the possession of "any poison, or any noxious or destructive substance".A doctor who examined the medicine chest of an Obeah man arrested in Jamaica in 1866 identified white arsenic as one of the powders in it, but could not identify the others. The unnamed correspondent reporting this affirmed "The Jamaica herbal is an extensive one, and comprises some highly poisonous juices, of which the Obeah men have a perfect knowledge."
During the mid 19th century the appearance of a comet in the sky became the focal point of an outbreak of religious fanatical millennialism among the Myal men of Jamaica. Spiritualism was at that time sweeping the English-speaking nations as well, and it readily appealed to those in the Afro-Caribbean diaspora, as spirit contact, especially with the dead, is an essential part of many African religions.
During the conflict between Myal and Obeah, the Myal men positioned themselves as the "good" opponents to "evil" Obeah. They claimed that Obeah men stole people's shadows, and they set themselves up as the helpers of those who wished to have their shadows restored. Myal men contacted spirits in order to expose the evil works they ascribed to the Obeah men, and led public parades which resulted in crowd-hysteria that engendered violent antagonism against Obeah men. The public "discovery"[according to whom?] of buried Obeah charms, presumed to be of evil intent, led on more than one occasion to violence against the rival Obeah men.
Laws were passed that limited both Obeah and Myal traditions but due to the outrages perpetrated by the mobs of Myalists, the British government of Jamaica sent many Myal men to prison[when?], and this, along with the failure of their millennialist prophecies[clarification needed].
Obeah in Trinidad and Tobago
One aspect of Obeah that is familiar to Trinidad and Tobago, though not all other nations where Obeah is practiced, is the Moko-Jumbie, or stilt dancer. Moko was a common word for Ibibio slaves. In the Trinidad and Tobago Obeah tradition. A Douen is a child who has died before being baptized, and is said to be forced to forever walk the earth at night in English-speaking regions of the Caribbean. Jewelry is made from deadly toxic red and black seeds called jumbies, jumbie eyes or jumbie beads (seeds of Abrus precatorius containing the lethal AB toxinabrin) in the Caribbean and South America. By contrast, the moko-jumbie of Trinidad and Tobago is brightly colored, dances in the daylight, and is very much alive. The moko-jumbie also represents the flip side of spiritual darkness, as stilt-dancing is most popular around holy days and Carnival.
Obeah in literature
Although 18th-century literature mentions Obeah often, one of the earliest references to Obeah in fiction can be found in 1800, in William Earle's novel Obi; or, The History of Three-Finger'd Jack, a narrative inspired by true events that was also reinterpreted in several dramatic versions on the London stage in 1800 and following. One of the next major books about Obeah was Hamel, the Obeah Man (1827). Several early plantation novels also include Obeah plots. In Marryat's novel Poor Jack (1840) a rich young plantation-owner ridicules superstitions held by English sailors but himself believes in Obeah.
The 20th century saw less actual Obeah in open practice, yet it still appears quite often in fiction and drama. The following is only a partial list:
A main character in the 2009 YA novel Three Witches by Paula Jolin (Roaring Brook/MacMillan)is a native of Trinidad and attempts to use Obeah to raise a dead classmate.
Several characters in the book "The Book of Night Women" by Marlon James are said to practice Obeah, and it is a focal point at a number of points in the novel.
In the book "The devil that follows me" A powerful Obeah woman named Mama Shirley is mentioned, and she's also visited by the main Character Scott Brown. Mama Shirley tells Scott Brown about what a duppy is, and he also seeks her help. The book can be seen here http://amzn.com/B00FXO7GL4
Bahamian singer Exuma recorded the song "Obeah Man", which was included on his eponymous debut album in 1970.
African American singer, pianist and civil rights activist Nina Simone took on the role of "Obeah Woman" in the song of the same name which she performed live on It Is Finished (1974). She used this image of a powerful African witch, who "could hug the sun, kiss the moon and eat thunder" to manifest her rage concerning the situation of African-Americans at the time.
The film Meet Joe Black features a Jamaican woman who calls the title character an "obeah man" (translated as "evil spirit") until she has learned that he is in fact a personification of Death.
Obeah is the religion listed on a computer screen of a 13 year old girl, Alisa Beldon, identified as a latent telepath in the Babylon 5 episode "Legacies" (Season 1, Episode 17).
In the television series version of Da Kink in My Hair hairstylist Starr chants to give herself strength which suspiciously sound like spells to some of the Caribbean clients of the West Indian hair salon. When styling church-going Sister Corrine the woman exclaims "Don't bother bring dat obia business to me...get this vodou witchcraft woman 'way from me head!" illustrating the contrasts between acceptance and disdain for obeah in the Caribbean.
In episode 2 of the 1974–1975 television series Kolchak: The Night Stalker, entitled "Zombie", a grandmother, identified as "Mamalois" (the feminine version of "papaloi", an Obeah priest), seeks revenge for her grandson's death by turning him into a zombie to do her bidding.
Obeah plays a major role in the 2001 horror movie "Ritual".
