Evidence from Muslim geographers and Ethiopian royal chronicles demonstrates that Oromos were in the Ethiopian Highlands as early as the Middle Ages. These societies maintained dynamic relations across frontiers—from the Christianized provinces of northern Shewa to the Muslim centers of Harar. Modern day Shewa was historically divided into three subdivisions: Gerra-Medir, Mamma-Midir, and Lallo-Midir. These names derive from three early rulers—Gerra, Mamma, and Lallo—who governed the region before the rise of the Shewan dynasty. Accounts describe them as Christianized rulers. Arabic sources from the 13th century describe a region called Gazla, also rendered as Karla or Garla. The Andalusian geographer Ibn Saʿīd al-Maghribī provided one of the earliest known accounts: "The land of Kazla begins from the equator, neighbouring the Zanj of al-Habasha, and stretches south of Mount Murus, which is said to provide the people of Janbeyta and those regions with gold and silver mines. It lies four days' journey from Janbeyta. To its east and north it extends from there, running eastward and bending northward until it cuts across the Nile of al-Habasha and ends at their sea." Historians such as Tadeusz Lewicki identified Gazla with the interior highlands of southern Ethiopia, likely inhabited by Cushitic-speaking peoples—possibly early Oromo populations. Its location near the sources of the Nile and south of the Abyssinian kingdom situates it between modern-day Bale, Arsi, and Hararghe. The references to mineral wealth and proximity to trade centers imply that Gazla was a politically organized and economically connected region. The description of Gazla "cutting across the Nile of al-Habasha and ending at their sea" indicates a geographical span from the Ethiopian interior to the Indian Ocean coast. This aligns with evidence for early trade routes linking the Ethiopian plateau with ports such as Mogadishu, Marka, and Brava, suggesting that Gazla served as a key corridor of cultural and commercial exchange between the interior and the Zanj coast. In medieval Ethiopian Christian literature, the term Arämi (አራሚ) was used to denote pagans, non-Christians, or infidels. It was especially applied to non-Christian Oromo groups and to Muslims living along the southern frontier of the Christian kingdom. The term could also function interchangeably with Tanbalat for Muslims, and in some cases was even extended to other foreigners. A miracle of Saint Täklä Haymanot, edited by Getatchew Haile (1984), refers to "the seven regions of the Arämi (Muslims)", which parallels the seven Islamic provinces mentioned by Arabic writers concerning the early Kingdom of Ifat. This linguistic and historical correspondence suggests that the Arämi of Ethiopian chronicles and the Gazla of Arabic geography refer to overlapping frontier zones — multi-religious regions where Oromo, Harla, Somali, and other Cushitic peoples interacted with both Christian and Muslim influences. The Oromo remained independent until the last quarter of the 19th century, when they lost their sovereignty. From 1881 to 1886, Emperor Menelik II conducted several unsuccessful invasion campaigns against their territory. The Arsi Oromo demonstrated fierce resistance against this Abyssinian conquest, putting up stiff opposition against an enemy equipped with modern European firearms. They were ultimately defeated in 1886. In the 1940s some Arsi Oromo together with people from Bale province joined the Harari Kulub movement, an affiliate of the Somali Youth League that opposed Amhara Christian domination of Hararghe. The Ethiopian government violently suppressed these ethno-religious movements. During the 1970s the Arsi formed alliances with Somalia. In 1967, the imperial regime of Haile Selassie I outlawed the Mecha and Tulama Self-Help Association (MTSHA), an Oromo social movement, and conducted mass arrests and executions of its members. The group's leader, Colonel General Tadesse Birru, who was a prominent military officer, was among those arrested. The actions by the regime sparked outrage among the Oromo community, ultimately leading to the formation of the Oromo Liberation Front in 1973. The Oromos perceived the rule of Emperor Haile Selassie as oppressive, as the Oromo language was banned from education and use in administration, and speakers were privately and publicly mocked. The Amhara culture dominated throughout the eras of military and monarchic rule. Both the imperial and the Derg government relocated numerous Amharas into southern Ethiopia, including the present day Oromia region, in order to alleviate drought in the north of the country. They also served in government administration, courts, church and even in school, where Oromo texts were eliminated and replaced by Amharic. Further disruption under the Derg regime came through the forced concentration and resettlement of peasant communities in fewer villages. The Abyssinian elites perceived the Oromo identity and languages as opposing the expansion of an Ethiopian national identity. In the early 1990s, the Ethiopian Democratic People's Republic began to lose its control over Ethiopia. The OLF failed to maintain strong alliances with the other two rebel groups at the time: the Eritrean People's Liberation Front (EPLF) and the Tigray People's Liberation Front (TPLF). In 1990, the TPLF created an umbrella organization for several rebel groups in Ethiopia, the Ethiopian People's Revolutionary Democratic Front (EPRDF). The EPRDF's Oromo subordinate, the Oromo People's Democratic Organization (OPDO) was seen as an attempted replacement for the OLF. On 28 May 1991, the EPRDF seized power and established a transitional government. The EPRDF and the OLF pledged to work together in the new government; however, they were largely unable to cooperate, as the OLF saw the OPDO as an EPRDF ploy to limit their influence. In 1992, the OLF announced that it was withdrawing from the transitional government because of "harassment and [the]assassinations of its members". In response, the EPRDF sent soldiers to destroy OLA camps. Despite initial victories against the EPRDF, the OLF were eventually overwhelmed by the EPRDF's superior numbers and weaponry, forcing OLA soldiers to use guerrilla warfare instead of traditional tactics. In the late 1990s, most of the OLF's leaders had escaped Ethiopia, and the land originally administered by the OLF had been seized by the Ethiopian government, now led by the EPRDF. Prior to the establishment of present-day Addis Ababa the location was called Finfinne in Oromo, a name which refers to the presence of hot springs. The area was previously inhabited by various Oromo clans. In 2000, Oromia's capital was moved from Addis Ababa to Adama. Because this move sparked considerable controversy and protests among Oromo students, the Oromo Peoples' Democratic Organization (OPDO), part of the ruling EPRDF coalition, on 10 June 2005, officially announced plans to move the regional capital back to Addis Ababa. Further protests sparked on 25 April 2014, against the Addis Ababa Master Plan, then resumed on 12 September 2015 and continued into 2016, when renewed protests broke out across Ethiopia, centering around the Oromia region. Dozens of protesters were killed in the first days of the protests and internet service was cut in many parts of the region. In 2019, the Irreecha festival was celebrated in Addis Ababa after 150 years of being banned.

Oromia shares a boundary with almost every region of Ethiopia except for the Tigray Region. These boundaries have been disputed in a number of cases, most notably between Oromia and the Somali Region. One attempt to resolve the dispute between the two regions was the October 2004 referendum held in about 420 kebeles in 12 districts across five zones of the Somali Region. According to the official results of the referendum, about 80% of the disputed areas have fallen under Oromia administration, though there were allegations of voting irregularities in many of them. The results led over the following weeks to minorities in these kebeles being pressured to leave. In Oromiya, estimates based on figures given by local district and kebele authorities suggest that 21,520 people have become internally displaced persons (IDPs) in border districts, namely Mieso, Doba, and Erer in the West Hararghe Zone and East Hararghe Zones. Federal authorities believe that this number may be overstated by as much as 11,000. In Doba, the Ministry of Federal Affairs put the number of IDPs at 6,000. There are also more than 2,500 displaced persons in Mieso. In addition, there were reports of people being displaced in the border area of Moyale and Borena zones due to this conflict. Towns in the region include Adama, Ambo, Asella, Badessa, Bale Robe, Bedele, Bishoftu, Begi, Bule Hora, Burayu, Chiro, Dembidolo, Fiche, Gimbi, Goba, Haramaya, Holeta, Jimma, Koye Feche, Metu, Negele Arsi, Nekemte, Sebeta, Shashamane and Waliso, among many others.

Oromo is written with Latin characters known as Qubee, only formally adopted in 1991 after various other Latin-based orthographies had been used previously. Oromo is one of the official working languages of Ethiopia and is also the working language of several of the states within the Ethiopian federal system including Oromia, Harari and Dire Dawa regional states and of the Oromia Zone in the Amhara Region. It is a language of primary education in Oromia, Harari and of the Oromia Zone in the Amhara Region. It is used as an internet language for federal websites along with Tigrinya. There are more than 33.8% Oromo speakers in Ethiopia and it is considered the most widely spoken language in Ethiopia. It is also the most widely spoken Cushitic language and the fourth-most widely spoken language of Africa, after Arabic, Hausa and Swahili languages. Forms of Oromo are spoken as a first language by more than 35 million Oromo people in Ethiopia and by an additional half-million in parts of northern and eastern Kenya. It is also spoken by smaller numbers of emigrants in other African countries such as South Africa, Libya, Egypt and Sudan. Besides first language speakers, a number of members of other ethnicities who are in contact with the Oromo speak it as a second language. See, for example, Harari, Omotic-speaking Bambassi and the Nilo-Saharan-speaking Kwama in northwestern, eastern and south Oromia.

• Illustration — The road to Lega Dembi gold mine Oromia is a major contributor to Ethiopia's main exports - gold, coffee, khat and cattle. Lega Dembi in Guji Zone, owned by MIDROC has exported more than 5000 kilograms of gold, followed by Tulu Kapi gold deposit in West Welega Zone. Awoday in East Hararghe Zone is the biggest market of khat exporting to Djibouti and Somalia. Oromia also has more abundant livestock than any other region of Ethiopia, including camels. It is also the largest producer of cereals and coffee. The CSA reported that, from 2004 to 2005, 115,083 tons of coffee were produced in Oromia, based on inspection records from the Ethiopian Coffee and Tea Authority. This represents 50.7% of the total production in Ethiopia. Farmers in the Region had an estimated total of 17,214,540 cattle (representing 44.4% of Ethiopia's total cattle), 6,905,370 sheep (39.6), 4,849,060 goats (37.4%), 959,710 horses (63.25%), 63,460 mules (43.1%), 278,440 asses (11.1%), 139,830 camels (30.6%), 11,637,070 poultry of all species (37.7%), and 2,513,790 beehives (57.73%).
