Outside of Cuba, Palo is generally called Palo Mayombe ; however, this is a misnomer since not all lineages and houses are truly Mayombe – in fact, most are not. To my knowledge there is only one (perhaps a couple) Munanzo outside of Cuba that are accepted as a true Mayombe houses amongst the elders on the Island.
In Cuba, “Palo Monte” is used far more frequently to speak to the entire body of Regla-Kongo Palo tradition. Other terms such as Palo Cruzado (‘crossed palo’, denoting heavy syncretization with other religions), Palo Cristiano (‘Christian palo’) and Palo Judio (‘Jewish palo’, not actually jewish, but simply non-Christian) deserve a brief mention. However, these are not specific ramas of Palo, but rather terms that are used to denote the degree of syncretism and mixing in individual lineages and practices.
There are many houses (munansos) and foundational lineages (ramas) of Palo Monte, but commonly they are understood to fit within three major forms or sub ‘reglas’ within the greater Regla-Kongo:
Mayombe
Biyumba (Vrillumba o Brillumba)
Kimbiza
Palo Mayombe is the oldest and most orthodox form of Palo. The origins trace back to a specific Nkisi cult in the Mayombe region of Cabinda (NW Congo) from where it gets its name and the tradition came into its own in the caves and wilderness of the Pinar del Rio highlands of Cuba. Mayomberos typically shun away from syncretism and are extremely orthodox in our practices. The most well known of the Mayombe houses are the houses of “Batalla Saca Empeño” and “Bejuco Nfinda”.
Palo Biyumba developed out of Palo Mayombe and rose in popularity during Cuba’s war of Independence. It was the first regla to initiate people of non-Bantu ancestry and frequently worked with and developed pacts with dead spirits of no particular blood or spiritual lineage (often times to send them out for warring intentions). It is a vast regla and has many ramas and sub-lineages. Indeed, a great number of houses today are some offshoot of Biyumba. Broadly speaking, Palo Biyumba is more oriented toward the various mpungos and over time some lineages have introduced a degree of syncretization with elements of Ocha and Catholicism.
Palo Kimbisa was popular on the eastern side of the Cuban island and has absorbed many influences from Catholicism to Freemasonry to Haitian Vodou. Kimbisa likely originated within an already syncretized Catholic-Kongo religious tradition from the Kingdom of Kongo following Kimpa Vita’s Christian reform in the 18th C. In Kimbisa the mpungos are paramount and are seen as divinities and saints. Thus, Kimbiseros will venerate the mpungos and focus much of their work calling upon them, instead of upon the dead. The most well known Kimbisa rama is Andrés Petit’s La Regla Kimbisa de Santo Cristo del Buen Viaje.
The Kimbisa prendas/ngangas I have seen also tend to be huge in comparison to Mayombe. Although my elders have reassured me that there are Kimbisa prendas that are built almost identical to Mayombe as there is more variance per house/lineage than across the greater sub-reglas. It is also common to see Kimbisa (as well as Briyumba) prendas with crucifixes. Moreover, many Kimbiseros and Biymberos will make a distinction between prendas judias or prendas ndoki(those without crucifixes and containing the bones of non-baptized individuals) used to curse, kill, and other malefica; and prendas cristianas (with cross and baptized nfumbe) used to heal and general benefica. This distinction does not appear in Mayombe.
