What is the difference between macumba and candomble?

Macumba is a syncretic religion practiced in Brazil, Argentina, Uruguay and Paraguay. It is sometimes considered by non-practitioners to be a form of witchcraft or black magic. Macumba was originally used to categorize all religions who practiced or believed in animistic-syncretism during the 1800s. In the 1900s Macumba became a slang term among Brazilians who are affiliated with these religions. The religions that are referred to under the umbrella term Macumba are Candomblé, Giro, and Mesa Blanca.
