For a period of about five centuries, Kagera was home to nine different kingdoms with highly hierarchical societies. Before European colonialism, coffee was a traditional crop in the area, used for its stimulant properties and in local cultural rituals. During colonial times, coffee was transformed into a cash crop. Bananas were a staple food in the region. Although there was a gender-based division of labour in the traditional Bahaya society, women of the time were not thought to be inferior to men. In fact women commanded special respect in all traditional rituals. For example, upon the death of a head of a family (Nyin'enju), during the following inheritance rituals the "Main Inheritor" (Omusika) had to have a female counterpart selected from among his sisters to share his authority. Similarly, upon the death of a reigning king, during the crowning of the next king, there had to be a "sister to the nation" ("Kinyany'engoma") who was also selected from among his sisters.
