2L - Mussolini and Empire: the invasion of Abyssinia and the conduct of the war
Learn why Italy invaded Ethiopia, how conquest was achieved, and why the war increased Mussolini's popularity while damaging collective security and changing Italy's international position.
From Walwal to invasion
Italy invaded Ethiopia, then commonly called Abyssinia in Europe, on 3 October 1935. Ethiopia was an independent state and a member of the League of Nations. Emperor Haile Selassie appealed to the League against aggression. The conflict was therefore not simply a dispute about dividing colonial territory among European powers.
Mussolini’s aims overlapped. Conquest promised to erase the memory of Italy’s defeat at Adwa in 1896, enlarge its African empire and demonstrate the vigour of Fascism. Ethiopia lay between Eritrea and Italian Somaliland, providing a geographical setting for expansion. Mussolini also expected a foreign success to strengthen support for his regime at home. Claims about land, resources and settlement supplied an economic justification, but did not establish that conquest would pay for itself.
The clash at Walwal in December 1934, where Ethiopian and Italian colonial forces confronted each other around a disputed frontier post, supplied an immediate pretext. It did not create the underlying imperial ambition. Italy demanded concessions and prepared large forces while diplomatic efforts continued. Treating Walwal as the sole cause hides the choice to turn a local dispute into a war of conquest.
Pretext and underlying cause
A pretext is a stated justification for action. An underlying cause explains the longer-term interests or pressures that make that action attractive. They can be different.
The international situation encouraged the gamble. France wanted Italy’s cooperation against Germany; Britain wished to avoid a Mediterranean conflict while supporting the League. Mussolini believed that their fear of alienating Italy would limit effective opposition. That expectation did not remove his responsibility for invasion: an opportunity to act and a decision to exploit it are separate elements of causation.
Conquest and the conduct of war
Italian forces attacked from Eritrea in the north and Somaliland in the south. Emilio De Bono initially commanded the northern advance; Mussolini replaced him with Pietro Badoglio in November 1935 when progress appeared too slow. Rodolfo Graziani commanded the southern campaign. This change shows how the demand for a rapid political victory affected military leadership.
Ethiopian armies resisted despite major disadvantages in aircraft, communications, artillery and mechanised equipment. Italian forces also used colonial troops, especially Eritrean askari; the army was not composed solely of men from the Italian mainland. Ethiopian forces achieved local successes and attempted to exploit difficult terrain, but could not match Italy’s ability to concentrate firepower and supplies. Badoglio’s offensives in early 1936 broke major northern armies; the defeat at Maychew on 31 March weakened Haile Selassie’s remaining conventional resistance.
The explanation must include the methods used. Italy employed mustard gas against Ethiopian forces and civilians, violating the 1925 Geneva Protocol. Italian aircraft also attacked protected medical units. Mussolini authorised chemical warfare; describing these acts only as unauthorised misconduct by individual soldiers removes leadership responsibility. The ICRC’s archival account documents attacks on Red Cross hospitals and the evidence surrounding violations.
Haile Selassie left the country, and Italian troops entered Addis Ababa on 5 May 1936. Mussolini proclaimed an empire on 9 May; Victor Emmanuel III became its claimed emperor. Ethiopia was combined with Eritrea and Italian Somaliland in Italian East Africa. The occupation of the capital and the proclamation did not mean that every area had accepted Italian control.
Resistance continued, and colonial authorities used executions, punitive operations and collective reprisals to impose rule. Following the attempted assassination of Graziani in Addis Ababa in February 1937, Italian reprisals killed large numbers of civilians; the later massacre at Debre Libanos targeted a religious community. Precise casualty estimates remain debated, but the organised repression is not in doubt. Empire depended on coercion and African resistance persisted after the conventional military defeat.
League sanctions and failed compromise
The League identified Italy as the aggressor and imposed economic sanctions in November 1935. Sanctions restricted loans and aspects of trade, but did not include a comprehensive oil embargo. Britain did not close the Suez Canal to Italian supply ships. Italy could obtain important materials from non-participating states, so the pressure raised costs without immediately preventing the campaign.
