Kaffa was divided into four sub-groups, who spoke a common language Kefficho, one of the Gonga/Kefoid group of Omotic languages; a number of groups of foreigners, Ethiopian Muslim traders and members of the Ethiopian Church, also lived in the kingdom. There were a number of groups of people, "but with the status of submerged status", who also lived in the kingdom; these included the "Manjo", or hunters; the "Manne", or leatherworkers; and the "Qemmo", or blacksmiths. The "Manjo" even had their own king, appointed by the King of Kaffa, and were given the duties of guarding the royal compounds and the gates of the kingdom. The kingdom was overrun and conquered in 1897, and was eventually annexed by Ethiopia.
