The Arbegnoch () were Ethiopian resistance fighters who opposed the Italian occupation of Ethiopia during the period of Italian East Africa (1936–1941).

Resistance began during the final stages of the Second Italo-Ethiopian War but took a more organized form after the Italian capture of Addis Ababa in May 1936. The movement evolved in two phases: an initial stage of semi-conventional warfare led largely by remnants of the imperial army and members of the upper nobility, followed by a prolonged period of guerrilla warfare after 1937 led by regional chiefs, local leaders, and fighters drawn from the broader population.

Encouraged by the exiled emperor Haile Selassie, resistance groups spread across much of the country, from Gondar in the north to Omo region in the south. The patriots relied on guerrilla tactics such as ambushing Italian convoys, destroying roads and bridges, attacking isolated garrisons, and disrupting communications. They were supported by local populations who supplied food, intelligence, and recruits, while clandestine agents known as Wust Arbegnoch (Insider Patriots) operated in towns under Italian control.

Despite limited weapons and the absence of centralized leadership, the resistance significantly weakened Italian authority outside major towns. By tying down large numbers of Italian troops in garrisons, the Arbegnoch helped pave the way for the Allied offensive in East Africa during World War II. In 1941, British and Ethiopian forces re-entered Ethiopia, and Haile Selassie returned to Addis Ababa, marking the end of Italian rule and the restoration of Ethiopian independence.

History Italian invasion A couple of months into the Second Italo-Ethiopian War on 9 December 1935, Ethiopian Minister of War Mulugeta Yeggazu ordered all chiefs in the north to undertake "patriotic resistance against the Italians for taking away the independence of Ethiopia". The Ethiopians first adopted guerrilla tactics in early 1936, when Ras Imru implemented a tactic of attrition through continuous guerrilla warfare. After deploying the bulk of his troops between Selekleka and Shire Enda Selassie, Imru sent several highly mobile units of 400 to 500 men to disrupt the Italian positions behind enemy lines. His men intercepted supply convoys and achieved important successes such as the annihilation of three bands of irregulars from the XXVII Eritrean Battalion, ambushing a convoy of vehicles near Damo Galilà, and destroying the ammunition depot at Mai Scium (whose explosion lost over 5,000 artillery shells and thousands of small arms rounds).

As disruption increased, the Italians were forced to deploy more troops to Tigray, away from the campaign further south. The Italians began referring to the rebels as shifta, which roughly translates from Amharic to English as "bandit"; the word also has a connotation of "one who rebels against an unjust authority", while the Ethiopians referred to them as Arbegnoch (). Addis Ababa fell to the advancing Italians on 5 May 1936 and the Ethiopians withdrew to nearby areas to regroup; Abebe Aregai went to Ankober, Balcha Safo to Gurage, Zewdu Asfaw to Mulo, Blatta Takale Wolde Hawariat to Limmu and the Kassa brothers (Aberra, Wondosson, and Asfawossen) to Selale. Haile Mariam conducted hit-and-run attacks around the capital. Emperor Haile Selassie fled the country with 117 chests of gold ingots which were used to fund his court in exile and the Patriots' activities.

The emperor left 10,000 troops under the command of Aberra Kassa with orders to continue resistance. On 21 June, Kassa held a meeting with Bishop Abune Petros and several other Patriot leaders at Debre Libanos, about north of Addis Ababa. Plans were made to storm the occupied capital but a lack of transport and radio equipment made it impossible to mount a coordinated attack. The deposed government in Gore was never able to provide any meaningful leadership to the Patriots or remaining military formations but sporadic resistance was undertaken by independent groups around the capital.

Beginning of the guerrilla war

The situation in Addis Ababa in the first weeks after the conquest was difficult for the Italians; communications were possible only through the long route from Eritrea, violence and disorder were widespread within the city, while Marshal Rodolfo Graziani, initially having only 9,000 soldiers, feared an attack by Ethiopian guerrillas who were reported "all around Addis Ababa"; there were rumors that many thousands of Arbegnoch were ready to attack. The situation of the Italians improved in mid-July with the arrival of substantial reinforcements which increased the garrison to 35,000 men; moreover, new exhortations were arriving from Rome to the governor to extend the occupation and to "be harsh, implacable with all the Abyssinians", Mussolini called for a "regime of absolute terror".

The Arbegnoch of Shewa were actually determined to attack Addis Ababa. In a meeting in Debre Libanos, with the presence of Aberra Kassa, Abune Petros and other leaders, a rash plan was decided to assault the capital with five separate columns, counting above all on exploiting a general uprising of the population. The assault began on 28 July 1936 on a foggy morning but, despite some successes, the guerrillas failed to coordinate their attacks; while Aberra Kassa's men arrived by surprise without encountering resistance as far as the center of Addis Ababa where they unleashed panic, Fikre Mariam was stopped by the course of a flooded stream and then blocked by reinforced Italian units. In the meantime, Abebe Aregai's Arbegnoch initially advanced almost as far as Graziani's residence but were then attacked by Eritrean askaris, the last two Ethiopian columns failed on the first day even to enter into the city due to the nearby floods. Fighting in Addis Ababa continued until 30 July 1936, the Arbegnoch of the Kassa brothers courageously held their positions despite counterattacks by the Italian-Eritrean forces led by generals Italo Gariboldi and Sebastiano Gallina, finally the guerrillas had to flee the city, due to attacks from the air force. One of the Arbegnoch leaders, Abune Petros was captured and immediately executed by the Italians.

While in Shewa the guerrillas dominated the countryside, the attempt to organize a solid resistance movement in the west of the Abyssinian territory was unsuccessful due to the opposition of the leaders of the Oromo population, who were traditionally hostile to Amhara rule. Marshal Graziani, urged by Mussolini, decided to intervene immediately in western Ethiopia by sending a small air expedition to Nekemte. On 26 June 1936 the Italian air expedition landed in Nekemte to meet with local Oromo chiefs who had wished to submit to Italian rule. The next night a group of guerrillas led by Kefle Nasibu and Belai Haile attacked the encamped Italians and massacred them. 12 Italians were killed and all of their aircraft were destroyed, among the dead were Italian aviators Vincenzo Magliocco and Antonio Locatelli. Despite this success, the Italians managed to foment the general revolt of Oromo tribes and on 8 October 1936 they returned to Nekemte where they welcomed the submission of important local leaders.

Anti-guerrilla operations of 1936 On 11 October 1936, the Minister of Colonies Alessandro Lessona had arrived in Addis Ababa, to confer personally with Marshal Graziani; regarding the tactics to be followed to crush the Ethiopian resistance and ensure total domination over the territory. After observing the ongoing fighting between guerrillas and Italian troops, the minister immediately entered into conflict with Graziani and the generals accused of not acting with the necessary energy to eliminate the resistance. The governor then issued new draconian orders stating that it was "time to put an end to weaknesses" and requesting to be regularly informed of the "number of people who have gone to arms". Lessona left Addis Ababa on 21 October while Marshal Graziani began the general autumn offensive against the guerrillas of Shewa.

On 27 October 1936, the Italians launched an offensive against the guerrillas near Ejere. Eritrean askaris overran the positions of the guerrillas and killed many of them, including the feared Ethiopian resistance leader Fikre Mariam. In the following weeks the Italians attacked the Shewan guerrillas in the Awash Valley, after fierce fighting, the Arbegnoch had to abandon the territories around the capital. The guerrillas of Gurage in southern Shewa led by Balcha Safo were attacked on 6 November 1936 by an Italian mechanized column led by Colonel Princivalle. After a valiant resistance the guerrillas were defeated and Balcha Safo was killed.

Imru Haile Selassie who was still resisting the Italians was forced to retreat south after the Welega Oromo submitted to Italian rule. The Italians followed him, and pinned him down on the north bank of the Gojeb River, where he surrendered on 19 December 1936. He surrendered together with the chiefs Keflè Nasibù and Belai Haile, and a group of "Youth Ethiopians".Mockler, Haile Selassie, pp. 163–168 On this occasion, Marshal Graziani decided to spare the life of the Abyssinian leader who, after consultations with Rome, was declared a prisoner of war and then deported to Italy.

After the failed attack on Addis Ababa, Wondosson Kassa decided to take refuge with his men around Mount Abuna Yosef before resuming guerrilla warfare in September 1936 near the town of Lalibela. Marshal Graziani took brutal measures against this resistance group, also employing, according to the instructions of Minister Lessona, mustard gases that were used extensively on the villages between Lalibelà and Bilbolà Ghiorghis. Wondosson Kassa was finally intercepted with his men near the source of Tekezé River and on 10 December 1936 was captured by Wollo Oromo collaborators, in the same evening he was then executed. The two other Kassa brothers (Aberra and Asfawossen), had taken refuge in Fiche, most of their men went to join the resistance leader of Abebe Aregai, they had agreed to surrender to the Italians and were captured by the troops of Ruggero Tracchia on 21 December 1936. The two Abyssinian leaders were then executed on 18:35 on the same day.

After the death of the Kassa brothers and the capture of Ras Imru, at the end of 1936 only Desta Damtew still remained active after having moved with about 2,000 men to the Sidamo region, in November he had repeatedly attacked the Italian forces of General Carlo Geloso before retreating to the mountainous region of Arbegona. With Dejazmach Gabremariam, Dejazmach Beyene Merid (Shum of modern Bale Province), and a dwindling number of soldiers, for the next few months Ras Desta eluded the Italians until they were trapped near Lake Shala in the Battle of Gogetti and annihilated. Wounded, Ras Desta managed to escape, only to be captured and hanged by Italian soldiers on 24 February 1937.Mockler, p. 172f His body left hanging for days the Italian authorities and the propaganda exalted the victory and the execution which seemed to symbolize the definitive victory of fascist Italy.

Attack on Graziani and reprisals

On 19 February 1937 – Yekatit 12 according to the Ge'ez calendar – saw the attempted assassination of Marshal Graziani by Eritrean rebels Abraham Deboch and Mogos Asgedom in Addis Ababa. The Italian response was immediate. According to Mockler, "Italian carabinieri had fired into the crowds of beggars and poor assembled for the distribution of alms; and it is said that the Federal Secretary, Guido Cortese, even fired his revolver into the group of Ethiopian dignitaries standing around him." Hours later, Cortese gave the fatal order:
