Second Italo-Ethiopian War

On 19 February 1937, an assassination attempt against the Italian viceroy Rodolfo Graziani in Addis Ababa set off one of the worst atrocities of the occupation. Italian authorities and colonial forces responded with days of mass killings, arrests, and destruction directed at Ethiopian civilians. Known as Yekatit 12 in the Ethiopian calendar, the massacre revealed the extreme violence underpinning Fascist rule after the supposed end of the war. It also demonstrated that conquest had not brought stability but rather intensified repression against a population still resisting occupation. The massacre remains central to Ethiopian historical memory and to scholarly assessments of Italian colonial violence in East Africa.

In July 1936, the League of Nations ended the sanctions it had imposed on Italy, despite the fact that Ethiopia remained under occupation and the conquest had not been accepted as lawful by many observers. The rollback made clear that the League lacked both unity and the coercive means to defend its own principles when confronted by a major aggressor. For contemporaries, the Abyssinian crisis became a devastating lesson: moral condemnation without effective enforcement could not stop expansionist war. The decision badly damaged the League’s credibility and is often cited as a major step in the disintegration of the interwar international order that preceded wider conflict in Europe and beyond.

On 30 June 1936, Haile Selassie addressed the League of Nations in Geneva in one of the most famous anti-aggression speeches of the twentieth century. Speaking as the ruler of a conquered member state, he warned that the League’s failure to act decisively against Italy would endanger all smaller nations and undermine the entire system of collective security. The speech also brought global attention to Italian atrocities, including chemical warfare. Although the League did not reverse the conquest, the address became a landmark in international political rhetoric. It preserved Ethiopia’s legal and moral case before world opinion and later gained lasting significance in African and anti-colonial memory.

On 9 May 1936, Benito Mussolini announced the annexation of Ethiopia and proclaimed the creation of an Italian empire in East Africa. King Victor Emmanuel III was declared emperor of Ethiopia, and the Fascist regime celebrated the conquest as proof of its power and imperial destiny. This proclamation gave formal political shape to what the military occupation had achieved days earlier. Yet the annexation was never fully secure, because substantial Ethiopian resistance endured and many states refused to treat the conquest as legitimate. The declaration nevertheless marked the high point of Fascist prestige before the later disasters of the Second World War exposed the fragility of Mussolini’s empire.

Italian troops entered Addis Ababa on 5 May 1936, completing the main military phase of the conquest. The occupation of the capital gave Mussolini the triumph he wanted and allowed Fascist Italy to present the war as concluded, even though resistance would continue in many regions. For Ethiopia, the fall of the capital was a catastrophe that brought looting, disorder, and then formal occupation rule. Internationally, the event dramatized the failure of the League of Nations to protect a member state from open aggression. The capture of Addis Ababa also shifted the conflict from conventional invasion to colonial occupation, repression, and guerrilla resistance across the country.

On 2 May 1936, with military collapse looming and Addis Ababa no longer defensible, Haile Selassie departed Ethiopia for exile. Before leaving, he arranged for a regent to continue what authority remained, but the withdrawal marked the effective breakdown of centralized imperial command during the invasion. His departure was controversial for some contemporaries, yet it also preserved the emperor as an international symbol able to continue the diplomatic struggle abroad. From exile, Selassie sought to expose the illegality and brutality of Italy’s conquest, especially the use of poison gas and attacks on civilians. His removal from the country underscored the scale of the disaster Ethiopia was facing.

On 31 March 1936, Emperor Haile Selassie personally led a major counterattack at Maychew, hoping to halt the Italian advance and restore Ethiopian morale. Instead, the battle ended in a decisive defeat. Italian troops under Badoglio were entrenched and supported by artillery, aircraft, and chemical weapons, while Ethiopian forces made brave but costly assaults without comparable equipment. Maychew is widely regarded as the last major battle on the northern front and a decisive turning point in the war. After the defeat, organized imperial resistance in the north unraveled, and the road toward Addis Ababa lay increasingly open to the invading army.

On 29 February 1936, Italian forces launched the Battle of Shire, another key offensive on the northern front. Coming immediately after Tembien, the battle struck Ethiopian forces that were already under enormous pressure and struggling to regroup. The Italian advance, supported by superior logistics and firepower, drove the defenders back and deepened the strategic crisis facing the Ethiopian command. Shire mattered because it compounded the cumulative effect of consecutive defeats rather than standing alone as an isolated clash. By early March, the defensive structure protecting the route to the heartland had been badly weakened, leaving the emperor with narrowing options and increasing urgency to attempt a decisive counterstroke.

From 27 to 29 February 1936, the Second Battle of Tembien dealt another crippling blow to Ethiopian resistance. Badoglio’s army attacked the forces of Ras Kassa and Ras Seyoum in Tembien Province after previous fighting in the same region. The battle is especially significant because Italian forces again used heavy aerial bombardment and mustard gas, magnifying their battlefield dominance and causing severe casualties. The defeat prevented Ethiopian commanders from re-forming an effective northern defensive line after Amba Aradam. Together with the nearby fighting at Shire, Tembien helped open the road southward and made it increasingly difficult for Emperor Haile Selassie to stabilize the front before the final drive toward the interior.

The Battle of Amba Aradam began on 10 February 1936 and developed into one of the decisive engagements of the war in northern Ethiopia. Italian forces under Pietro Badoglio attacked Ethiopian armies gathered around the massif, using coordinated artillery, aircraft, and, notoriously, chemical weapons including mustard gas. The Ethiopian defenders fought from rugged highland terrain but were outmatched by concentrated modern firepower. The Italian victory shattered one of the largest Ethiopian field forces and accelerated the collapse of organized resistance in the north. Amba Aradam therefore marked a crucial transition from hard-fought campaigning to a succession of Italian breakthroughs that pushed toward the imperial center of Ethiopia.

Between 10 and 13 January 1936, forces under Rodolfo Graziani launched a major offensive in the south at the Battle of Ganale Doria. Ethiopian troops under Ras Desta Damtew had advanced into the Ogaden, but they faced Italian superiority in aircraft, firepower, and mobility. The battle ended in an Italian victory that disrupted Ethiopian hopes of mounting a sustained threat from the southeastern front. It also demonstrated how the war was being fought on multiple axes, not only in the north where the main invasion had begun. The fighting around the Ganale Doria River further revealed the increasing importance of air power and mechanized colonial warfare in determining the campaign’s outcome.

On 18 November 1935, the League of Nations put economic sanctions into effect against Italy after identifying it as the aggressor. The move was one of the League’s most important collective-security tests, yet the sanctions were limited and excluded key materials such as oil. Major powers were unwilling to take the stronger steps needed to halt Mussolini’s campaign, and the Suez Canal remained open to Italian traffic. As a result, the penalties carried moral and diplomatic significance but failed to stop the invasion. The sanctions episode became a lasting example of the League’s inability to enforce its principles against determined expansionist states.

Italian troops seized Aksum on 15 October 1935, extending their early advance into one of Ethiopia’s most revered historic centers. Aksum was not only a strategic northern town but also a place associated with Ethiopia’s ancient monarchy, Orthodox Christian heritage, and long imperial tradition. During the occupation, the famous Aksum obelisk was removed and sent to Rome, turning conquest into a symbolic act of imperial appropriation. The capture reinforced the message that the war was aimed not merely at defeating an army but at subordinating an independent African state with deep historical legitimacy to Fascist colonial rule.

Just three days after crossing the frontier, Italian forces occupied Adwa, the northern Ethiopian town whose name carried enormous symbolic weight. Adwa was where Ethiopia had decisively defeated Italy in 1896, preserving its sovereignty and becoming an anti-colonial symbol across Africa and the wider Black world. The 1935 capture therefore had significance beyond military geography: it was presented by the Fascist regime as revenge for national humiliation and proof that modern Italy had erased the memory of earlier defeat. The fall of Adwa also showed how rapidly the northern front was moving in Italy’s favor during the opening phase of the campaign.

On 3 October 1935, Mussolini’s forces launched a full-scale invasion of Ethiopia, attacking from Italian Eritrea in the north and from Italian Somaliland in the southeast. The assault came after Italy rejected diplomatic efforts and arbitration. The campaign was marked by overwhelming Italian advantages in artillery, aircraft, armor, and logistics against an Ethiopian army that contained many brave but poorly equipped formations. The invasion exposed the weakness of interwar collective security, because the League of Nations condemned the aggression but could not stop it. Historians often view this date as one of the key steps on the road toward the wider international breakdown that culminated in the Second World War.

A clash at the oasis wells of Walwal in the disputed Ogaden borderland became the direct diplomatic trigger for the Second Italo-Ethiopian War. Fighting broke out between Ethiopian forces and an Italian-backed colonial garrison after weeks of tension over rival claims and military encroachment. Although the League of Nations later pursued mediation, Fascist Italy used the incident to intensify propaganda, mobilize troops, and frame Ethiopia as the aggressor. The confrontation transformed a border dispute into an international crisis and gave Benito Mussolini the excuse he needed to pursue a long-prepared invasion intended to avenge Italy’s 1896 defeat at Adwa and expand its East African empire.
