Greater Somalia or Greater Somaliland (; ), is the geographic location comprising the regions in the Horn of Africa in which ethnic Somalis live and have historically inhabited.
During the Scramble for Africa at the end of the 19th century, Somali-inhabited territories were partitioned between imperial powers. The unification of these territories became a focal objective of an independent Somalia. Referred to as "Greater Somalia," these regions, at the outset of Somali independence, encompassed State of Somaliland (former British Somaliland) and Trust Territory of Somaliland (former Italian Somaliland), which had successfully merged into a single nation in 1960. French Somaliland, the Northern Frontier District (NFD) in Kenya, and the Ogaden region in Ethiopia were placed under the control of neighboring states, despite the pre-independence unification efforts of Somali nationalists.
The post-independence governments of the Somali Republic (1960–1969) and the Somali Democratic Republic (1969–1991) expended significant effort towards the unification of the NFD and French Somaliland with Somalia; however, their primary focus was the Ogaden region, which had been occupied by Ethiopia since Menelik's invasions in the 1890s. From 1960 onwards, Somalis in Ethiopia and Kenya seeking self-determination have waged several insurgencies with the support of neighbouring Somalia, such as the Shifta War, escalating into several major interstate conflicts including the 1964 Ethio-Somali War and 1977 Ogaden War in Ethiopia.
However, following the breakout of the Somali Civil War and the splintering of Somalia into various autonomous polities, the concept of Greater Somalia has seen a decline in support, with some Somali diaspora communities advocating for autonomy or secession (such as Puntland and Somaliland) rather than a fully-fledged union.
History Since the early 20th century, the vision of Greater Somalia has taken shape, aiming to unite all Somali-inhabited regions in the Horn of Africa into a single nation. This concept, known as Pan-Somalism, seeks to consolidate these territories into one cohesive Somali state. The pursuit of this ideal has fueled conflicts, notably Somalia’s role in the Ogaden War with Ethiopia over the Somali Region and its support for Somali insurgents against Kenya. In 1946, the Somali Youth League proposed Harar as the future capital of Greater Somalia, dispatching delegates to the United Nations office in Mogadishu to advocate for this vision.
Colonialism The colonisation of Somali territories during the Scramble for Africa in the late 19th and early 20th centuries involved multiple European powers and the Ethiopian Empire, driven by strategic and economic interests. The United Kingdom, France, and the Kingdom of Italy were the primary colonial powers vying for control of Somali-inhabited regions, motivated mainly by the need for trade routes and geopolitical dominance. Emperor Menelik's expansion into Somali inhabited territory coincided with the European colonial advances in the Horn of Africa, during which the Ethiopian Empire imported a significant amount of arms from European powers. The large scale importation of European arms completely upset the balance of power between the Somalis and the Ethiopian Empire, as the colonial powers blocked Somalis from receiving firearms.
Britain established a protectorate in northern Somalia (modern-day Somaliland) by signing treaties with the local Isaaq clans in the 1880s, guaranteeing nominal independence but controlling trade and order at ports like Berbera. Many of these clans had signed the protection treaties with the British in response to Ethiopian Emperor Menelik's Invasions. The agreements dictated the protection of Somali rights and the maintenance of independence.
France developed Djibouti as a coaling station, formalising French Somaliland in 1884, which remained a colony until 1977 when it later became the Republic of Djibouti. Italy also acquired southern Somali territories, establishing Italian Somaliland by 1889.
The Anglo-Ethiopian Treaty of 1897 granted the Ethiopian Empire sovereignty over the Ogaden and Haud regions, an effectively illegal action by the British Empire, since the treaty directly contravened the protection agreements Britain had previously concluded with several Somali clans. The Dervish Movement however, led by Sayyid Mohammed Abdullah Hassan, was a significant anti-colonial movement that united various Somali clans, repelled British and Ethiopian forces multiple times, and created a proto-state. The Dervish movement was defeated in 1920 by the British launching a combined air and ground campaign—the first major aerial bombardment in Africa. The anti-colonial resistance of the Dervish movement and other groups fostered early Somali nationalism and resentment against the borders imposed by colonial powers, laying ideological groundwork for Greater Somalia.
During World War I, the British entered into an agreement with Italy, promising to transfer control of a significant part of the Jubaland protectorate, a region located in southwestern Somalia. Italy, in return for joining the Allied powers, was to be granted this substantial portion of land. In 1924, Trans-Juba was transferred to Italian Somaliland as stipulated in the wartime pact.Alex Thomson, "An Introduction to African Politics", 2 edition, (Routledge: 2000), p.23 Britain retained control of the southern half of the partitioned Jubaland territory, which was later merged into the Northern Frontier District (NFD) of Kenya.
Over the next few years, Britain and Italy solidified control over their respective Somalilands, while France governed Djibouti. Somali-inhabited areas in the Northern Frontier District and the Ogaden region remained under foreign rule. During this time, Somali clans faced considerable economic marginalisation and restricted movement due to colonial boundaries, fueling discontent. They were largely excluded from administrative roles, with the colonial authorities favoring European settlers or imported labor, which limited political influence and economic opportunities for them. Additionally, colonial education and economic systems were designed to serve the colonisers’ needs, offering minimal benefits to Somalis and eroding their cultural practices.
In the 1920s and 1930s, there were no permanent Ethiopian settlements or administration in any Somali inhabited land, only military encampments. Due to native hostility, the Ogaden region was barely occupied by Ethiopian authorities, who exerted little to no presence east of Jijiga, until the Anglo-Ethiopian boundary commission in 1934 and the Wal Wal incident in 1935. The incident at Wal Wal ignited the Second Italo-Ethiopian War and paved the way for Italy’s occupation of Ethiopia. It arose from a dispute over the poorly defined border between Ethiopia and Italian Somaliland. Britain and Ethiopia had established a joint boundary commission to clarify the Somali-Ethiopia border. However, the commission’s work was incomplete, and disagreements persisted, which left the region’s status ambiguous.
By 1936, Italian forces had captured Addis Ababa, leading to the military occupation of Ethiopia and the proclamation of Italian East Africa, which incorporated Ethiopia, Eritrea, and Italian Somaliland. In a bid to gain support among the Somali population, the Italians pushed forth their own vision of the Greater Somalia's realization within Italian East Africa.Tripodi, Paolo. The Colonial Legacy in Somalia p. 104 (New York, 1999) During World War II, Italian forces invaded and occupied British Somaliland. In 1940, Mussolini boasted to a group of Somalis in Rome that with the conquest of British Somaliland, nearly all Somali lands were united, fulfilling their dream of a union of all Somalis.Antonicelli, Franco. Trent'anni di storia italiana 1915 - 1945. p. 47
However the British regained control of British Somaliland, liberated Ethiopia from Fascist Italy and conquered Italian Somaliland by 1941.Federal Research Division, Somalia: A Country Study, (Kessinger Publishing, LLC: 2004), p.38 Following World War II, Somali leaders in the Ogaden region of Ethiopia repeatedly put forward demands for self-determination, only to be ignored by both Ethiopia and the United Nations. The Potsdam Conference was held in 1945, where the Allied powers decided to not return Italian Somaliland to Italy. The UN opted instead in 1949 to grant Italy trusteeship of Italian Somaliland for a period of ten years, after which the region would become independent.Aristide R. Zolberg et al., Escape from Violence: Conflict and the Refugee Crisis in the Developing World, (Oxford University Press: 1992), p.106
Meanwhile, in 1948, under pressure from World War II allies and to the dismay of Somalis, the British returned the Haud (an important grazing area that was presumably "protected" by British treaties with the Somalis in 1884 and 1886) and the Ogaden Region to Ethiopia, based on the Anglo-Ethiopian Treaty in which the British ceded Somali territory to Menelik II in exchange for his help fighting against the Somali clans.David D. Laitin, Politics, Language, and Thought: The Somali Experience, (University Of Chicago Press: 1977), p.73 Britain included the proviso that the Somali residents would retain their autonomy. Regardless, Ethiopia immediately claimed sovereignty over the Haud region. This prompted an unsuccessful bid by Britain in 1956 to buy back the Somali lands that it had turned over.
In the mid-1950s, Ethiopia gained full control over the Ogaden region for the first time and began incorporating it into Ethiopian imperial administration. Virtually no infrastructure was developed there, with scarcely any paved roads, electricity lines, schools, or hospitals constructed. The Ethiopian presence primarily consisted of soldiers and tax collectors. The Somalis were discriminated against by the ruling Amhara elite, and were poorly integrated into the Ethiopian Empire. In 1958, the UN Trusteeship Council established an arbitration tribunal to resolve the territorial dispute between Ethiopia and Somalia but the effort proved ineffective. The Somalis consistently rejected the 1897 Anglo-Ethiopian delimitation and refused to recognise its legal validity. Growing discontent fueled demands for Somalis to take control of Somali majority areas.
Independence After Somalia’s independence in 1960, successive governments launched a campaign to reclaim what they termed "lost territories," raising the issue with regional and international bodies such as the United Nations. In a meeting with Israeli Defense Minister Moshe Dayan, the Ethiopian Emperor Haile Selassie asserted that the Somali nationalist aspiration for a Greater Somalia was driven by Nasserite agitation, and expressed hope to the Israelis that the Somali Republic itself would eventually be incorporated into the Ethiopian Empire.
The newly formed Somali government and army had felt pressured and obliged to respond to what Somali citizens widely perceived as oppression of their brethren by an Ethiopian military occupation. In a bid to control the population of the region during the 1963 Ogaden revolt, an Ethiopian Imperial Army division based out of Harar torched Somali villages and watering holes were machine gunned by aircraft in order to control the regions overwhelming nomadic population by denying them access to water. The Americans and Israelis assisted the Ethiopians in violently suppressing the Somali nationalist struggle in the Ogaden. In 1964, the first Ethiopian-Somali War erupted along the border, ending in an armistice after two months of interstate fighting.
