This population of horses owes its name to the biotope in which it has long evolved in the wild, Mount Kundudo.^[1][2][3][4] Very little is known about their history, as there are no written sources.^[2][5] Oral tradition, gathered from the oldest local inhabitants, has it that these horses have been known for over 200 years, and that the future emperor Haile Selassie I captured one of them with the help of his uncle, at the age of 10.^[2][6] One oral hypothesis as to the origin of these horses is that their ancestors were military mounts left behind after the Ethiopian-Adal war, which pitted Muslim chief Ahmed Gragn against Christian chief Dawit II from 1528 to 1560.^[2][5][7] It is possible that a small group of 10 to 15 horses survived for decades despite the past presence of lions and cheetahs.^[6] However, there is no tangible evidence in favor of an origin theory.^[8][9][10] The relatively close genetic distance between the Kundudo wild horses and the domesticated Abyssinian horses suggests, however, that the Kundudo may be a sub-population of Abyssinian horses that returned to the wild in the recent past,^[11][12][13] perhaps during the military events of the 16th century.^[12][13]

The horses of Mount Kundudo were rediscovered at the beginning of the 21st century, when a team led by Ethiopian researcher Effa Delesa Kefena explored the ecozones specific to Ethiopian horses.^[5] This research highlighted the difficulties of communicating about Ethiopian horses, which are not even well known locally.^[10] On 3 January 2008, the researchers first found a single mare, around 11 years old, with a hooves that had never been groomed and showing no signs of domestication.^[6] They took a DNA sample and nicknamed her "Basra ".^[6] In October 2010, they counted a total of 18 horses in the mountain area.^[5][8] In 2013, a survey expedition was sent by the Ethiopian Biodiversity Institute, which counted just 11 horses.^[5]

There is no stud book.^[1] These horses are undergoing a process of re-domestication,^{[1][9][14][15]} as some of them are captured annually by a local farmer, to be put to work.^[5]

Their morphology is described as faulty, with irregular shapes, short backs with plunging toplines, and paunchy bellies.^[1][14][16] However, the small number of horses studied means that no consistent morphological data can be deduced.^[17][18]

Kundudo horses are one of eight horse breeds identified in Ethiopia.^[19] And, along with the Borana (the Ethiopian breed from which it diverges the most^[20]) Kundudo horses are most distant genetically from the other Ethiopian horse breeds.^[11][21] This study attributes one gene cluster to Kundudo alone.^[21] The Ethiopian breed closest to Kundudo is the Abyssinian.^[11] The population also shows low genetic diversity,^[11] the lowest of all Ethiopian horse populations studied.^[22] It is likely that these horses have undergone a phenomenon of genetic drift, due to the low number of founder individuals, isolation over a long period of time, and the absence of crossbreeding with horses of external origin.^[23] However, their genetic heritage is neither exceptional nor unique compared to other equine populations of this type.^[24]

Although these horses have returned to the wild, and constitute one of Africa's three "wild" horse populations,^[25] some of them are regularly captured by a local farmer who puts them to work for harvest time, before releasing them.^[6] They are considered to be of little use for this purpose, with little pulling power, and are resistant to the work demanded of them.^[6] However, this farmer may have captured or sold some of the foals.^[6]

Studies suggest that the grazing area at the top of Mount Kundudo could gradually be turned into a tourist attraction, along the lines of the Namib horse attraction,^[6] based on the tourism potential of wild horse watching.^[26] The Namib horses are known worldwide, wrongly, as the only "wild" horses in Africa.^[2]

The DAD-IS database provides no data on numbers,^[1] but the herd is tiny.^[27] These horses are essentially local, confined to the Mount Kundudo region of eastern Ethiopia,^[1][14][16] where they are reputed to be rare.^[9] They graze on an area of 13 hectares, and drink from a waterhole at the top of the mountain, which never dries up, even in the hot season.^[6] They are the last wild horses in East Africa.^[6] They are highly threatened with extinction, due to their rarity, consanguinity, poor breeding practices and the demand for their foals.^[1][8] Since 2011, this animal population has been classified as critically endangered.^[5] The Ethiopian Biodiversity Institute has put in place conservation procedures, including the freezing of stallion semen.^[5] The breed's importance in terms of its link with Ethiopian history was emphasized.^[28]

In 2016, CAB International listed the breed as "potentially extinct", the last recorded population of 11 horses in 2013 being too low to ensure the population's sustainability.^[9]
