Palo, also known as Las Reglas de Congo, is a religion with various denominations which developed in Cuba among Central African slaves and their descendants who originated in the Congo Basin. Denominations often referred to as "branches" of Palo include Mayombe (or Mallombe), Monte, Briyumba (or Brillumba), and Kimbisa.
The Spanish word palo "stick" was applied to the religion in Cuba due to the use of wooden sticks in the preparation of altars, which were also called la Nganga, el caldero, nkisi or la prenda. Priests of Palo are known as Paleros, Tatas (men), Yayas (women) or Nganguleros. Initiates are known as ngueyos or pino nuevo.
Palo has its roots in the Congo Basin of Central Africa, from where large numbers of Kongo slaves were brought to Cuba where the religion was organized. Palo's liturgical language is a mixture of the Spanish and Bantu languages, known as lengua, bozal or habla Congo.
The Palo belief system rests on two main pillars:
All natural objects, and particularly sticks, are thought to be infused with powers, often linked to the powers of spirits.
A certain number of spirits called Kimpungulu (singular: Mpungu) inhabit the Nkisi (sacred objects; also spelled Enkisi, Inquice, or Inquise). Kimpungulu are well known in name and deed, and are often venerated as spirits with anthropomorphic qualities. They are powerful entities, but they are ranked below the Supreme Creator Zambi or Nzambi, making Palo a henotheistic religion.
The main practice of Palo focuses upon the religious receptacle or altar known as "la Nganga", "el caldero", "nkisi" or "la prenda". This is a consecrated vessel which serves as a microcosm. Each Nganga is dedicated to a specific mpungu. Often, this religious vessel is also believed to be inhabited by a spirit of the dead (almost never the direct ancestor of the object's owner), also referred to as "Nfumbe", who acts as a guide for all religious activities which are performed with the Nganga.
