The Kingdom of Gumma was one of the five Oromo kingdoms located in Western Ethiopia. The Kingdom of Gumma originated in the early nineteenth century CE and had its capital located in Chora. [1] Like its neighbouring Oromo kingdoms, the Kingdom of Gumma seemed to be politically and administratively similar to the Kingdom of Jimma. [2] The Kingdom of Gumma was an Islamic kingdom and was particularly active in Jihadis movements in the second half of the nineteenth century. [3] The Kingdom of Gumma was eventually annexed into the Ethiopian Empire by Menelik II at the turn of the twentieth century. [4]

“To the south of the two kingdoms of Guma and Limmu are still mainly in the basin of the Orghesa or Didesa, one of the largest but on of the least known rivers in the Abai system. The town of Chora, capital of Guma, is situated on an affluent of this watercourse.” [1]

“The kingdom of Guma arose at the start to the nineteenth century, one of a cluster of small kingdoms in a region known as Gibe.” [1] “Shortly before the conquest of Menelik these states headed by Guma began to raid the pagan states of Leqa Horda, Leqa Billo, Nole Kabba, and Hanna Gafare, who leagued together as ‘the Four Pagans’ (arfa Oromata) which caused the other coalition to distinguish itself by the title of ‘the Four Muslims’ (arfa naggadota).

“Fourth, the Muslim resistance in Wallo seems also to have led to the growth of a Jihadic movement in the Gibe region. The Muslim clerics who made Islam the religion of the masses and nurtured Islamic culture in Wallo, brought the spirit of resistance with them to the Gibe region.

levels. The following quote suggest that the military hierarchy of the Kingdom of Gumma was similar to that of the Kingdom of Jimma. “Little has been said about the neighboring Galla states of Limmu, Gomma, Guma, and Gera. There is not enough evidence available about these monarchies to be able to compare them with Jimma structurally. It is possible to say, on the basis of Cecchi’s account primarily, that these kingdoms shared a number of features with Jimma. [...] All had similar border guards, customs gates, alarm drums, and war organization. In these respects they shared a common political culture with Jimma.” [1] Hierarchy for the Kingdom of Jimma: 1.King :“The armed forces of the kingdom were under the direct control of the king and his military leaders.” [2] :2. Minister of War ::“Before the turn of the century, Abba Roro’s son, Abba Digga, became Abba Jifar’s war minister and one of his closest confidants.” [3] ::3. General :::“Abba Gojam Babella, a leading general and governor who fought in the wars at the turn of the century, and whom many legends are told, was from Gera.” [4] :::4. Lesser officers (it seems reasonable to infer the existence of at least one intermediary level between generals and soldiers) ::::5. Soldiers, e.g. Abba k’oro k’awe (governor’s rifles) and foreign mercenaries :::::“Two of these groups, the abba k’oro k’awe (governor’s rifles) and the Jeberti were made of local men who served for only one week out of four and who were repaid with exemption from taxation and corvee service.” [5] Jeberti- “Two of these groups, the abba k’oro k’awe (governor’s rifles) and the Jeberti were made of local men who served for only one week out of four and who were repaid with exemption from taxation and corvee service.” [5] Foreign Mercenaries- “The third group was made up of 1,500 mercenaries from such northern regions as Shoa, Wollo, Gojam, and Gondar.” [6]

levels. Four levels mentioned by Herbert S. Lewis’ quote below. Highly likely there are more levels present. The following quote suggests that the Kingdom of Gumma was structured similarly to the other Oromo kingdoms, especially the Kingdom of Jimma. An expert would, however, need to confirm this. “Little has been said about the neighboring Galla states of Limmu, Gomma, Guma, and Gera. There is not enough evidence available about these monarchies to be able to compare them with Jimma structurally. It is possible to say, on the basis of Cecchi’s account primarily, that these kingdoms shared a number of features with Jimma. For example, the kings were not considered sacred personages but they did stand out above any other political figures in these states. In Cerulli’s collection of folktales and poetry all the warriors and heroes appear to be directly subservient to the kings. These kingdoms were organized into provinces (k’oros) with abba gandas below the abba’koros. The official called the abba mizan (‘father of the scales’) in Gera seems to have been the same as the nagadras in Jimma. All had similar border guards, customs gates, alarm drums, and war organization. In these respects they shared a common political culture with Jimma.” [1] 1.Monarch:2. Vizier/close adviser (inferred from similar polities) ::3. Lesser court officials (inferred from similar polities) :::4. Governors (abba k’oros) ::::5. Lesser provincial officials (inferred from necessity to administrate provinces) :::::6. District head (abba ganda) ::::::7. Lesser district officials (inferred from necessity to administrative districts :::::::8-12. NB 12 is the number of levels we assigned to Jimma based on the literature consulted for that polity.

Through Hirmata (where the modern town of Jimma is situated) passed caravans to the southwest (to Kafa, Maji, Gimira); the south (Kullo, Konta, Uba, and elsewhere); to the west (Gomma, Guma, Gera Ilubabor); and north to Limmu, Nonno, Shoa, Wollo, and Gondar.” [1]

“The Maria Theresa dollar, known as the thaler in Austria, was first minted in Vienna in 1751 and named after the Austrian Empress Maria Theresa. It was 80 percent pure silver. In the late 18th century, Arab traders probably introduced the Maria Theresa thaler to Ethiopia and, by the mid-19th century it had become the most widely acceptable form of currency. Before 1935, the coinage of Menelik II and Halie Selassie failed to dislodge the thaler. During the Italian-Ethiopian War (1935-1936), there were some 50 million thalers in circulation. [1]
