The Rastafari movement, or Rasta, is a spiritual movement. It arose in the 1930s in Jamaica, a country with a predominantly Christian culture where 98% of the people were the black descendants of slaves.

Most of its adherents worship Haile Selassie I, Emperor of Ethiopia (ruled 1930–1974), as God incarnate, the Second Advent, or the reincarnation of Jesus. Members of the Rastafari movement are known as Rastas, or Rastafari.

The name Rastafari is taken from Ras Tafari, the pre-regnal title of Haile Selassie I, composed of Amharic Ras (literally meaning “Head”, an Ethiopian title equivalent to Duke), and Haile Selassie’s pre-regnal given name Tafari.

[edit]Jah
“ … Ethiopia shall soon stretch out her hands unto God. ”
— Psalms 68:31
Rastafari are monotheists, worshipping a singular God whom they call Jah. Jah is the term taken from the “KJV” (King James Version of the Bible), Psalms 68. 

Rastas see Jah as being in the form of the Holy Trinity, that is, Father, Son and the Holy Spirit. Rastas say that Jah, in the form of the Holy Spirit (incarnate), lives within the human, and for this reason they often refer to themselves as “I and I”.
