In order to avoid the danger of losing the socio-cultural practice of the ancestor, and the overall precolonial activities such as the Mandyeng, Nshok, Worom Chun, Vwana, ceremonies were brought into a single umbrella festival called Nzem Berom.
In the past the Berom regard Mandyeng/Nshok (they are very similar) the most vital festivals which ensured a good farming and hunting period and harvest.
Those that perform 'Mandyeng' claim their roots from Riyom, they include; Vwang, Kuru, Zawan, Gyel, Rim, Bachit, Bangai, Lwa, Sop, Jol, Wereng Kwi, Gwo, Kakuruk, Kuzeng, Kurak, Kuchin, Rahos and Tahoss.
[6] So much so, that most Berom names are derived from game animals, most importantly duiker[citation needed], due to their perceived beauty.
Berom ancestral lands are all located on high ground on the Jos plateau; beautiful scenery and undulating terrains.

24p/1916[JOS PROF NAK 473/1916], dated 15 August 1917, the Resident at Bauchi Province was instructed to send potentials from various native authorities including district and village heads to be elevated as chieftains by the Governor General.
[citation needed] In the pre-colonial period, the Berom were divided into autonomous political groups based on regions, but the colonial authority merged them under the Gbong Gwom in 1952 to help coordinate the activities of the natives.
[15] Under Dachung Gyang, the traditional institution was designated as the Berom Tribal Council[16] composing of local chiefs within the Jos Native Authority.
[citation needed] The emergence of Da Rwang Pam (1947 to his death on 14 July 1969[17] saw the elevation of the head of the Tribal Council to the stool of the Gbong Gwom Jos.
