The Battle of Omdurman was fought during the Anglo-Egyptian conquest of Sudan between a British–Egyptian expeditionary force commanded by British Commander-in-Chief (sirdar) major general Horatio Herbert Kitchener and a Sudanese army of the Mahdist State, led by Abdallahi ibn Muhammad, the successor to the self-proclaimed Mahdi, Muhammad Ahmad. The battle took place on 2 September 1898, at Kerreri, 11 kilometres (6.8 mi) north of Omdurman.
The Battle of Umm Diwaykarat on 25 November 1899 marked the final defeat of the Mahdist State in Sudan, when Anglo-Egyptian forces under the command of Lord Kitchener defeated what was left of the Mahdist armies under the command of the Abdallahi ibn Muhammad, known as the Khalifa, after the equally disastrous Battle of Omdurman a year earlier.
Yohannes IV was Emperor of Ethiopia from 1871 to his death in 1889 at the Battle of Gallabat, and governor of Tigray from 1869 to 1871. During his reign he successfully defended Ethiopia against a large-scale Egyptian invasion.
The Solomonic dynasty, also known as the House of Solomon, was the ruling dynasty of the Ethiopian Empire from the thirteenth to twentieth centuries. The dynasty was founded by Yekuno Amlak, who overthrew the Zagwe dynasty in 1270. His successors claimed he was descended from the legendary king Menelik I, the supposed son of the biblical King Solomon and the Queen of Sheba, in order to legitimize the dynasty's assumption of power. Although this claimed ancestry gave the dynasty its name, there is no credible evidence that the dynasty was descended from Solomon or the Davidic line. The Solomonic dynasty remained in power until 1974, when its last emperor Haile Selassie was overthrown by a coup d'état.
El-Gadarif, also spelt Gedaref or Gedarif, is the capital of the state of Al Qadarif in Sudan. It lies on the road that connects Khartoum with Gallabat on the Ethiopian border, about 410 kilometres (250 mi) from the capital.
Gallabat is a village in the Sudanese state of Al Qadarif. It lies at one of the country's border crossing points with Ethiopia; on the other side of the border is Ethiopia's corresponding border village Metemma.
The River War: An Historical Account of the Reconquest of the Soudan (1899), by Winston Churchill, is a history of the conquest of the Sudan between 1896 and 1899 by Anglo-Egyptian forces led by Lord Kitchener. He defeated the Sudanese Dervish forces, led by Khalifa Abdallahi ibn Muhammad, heir to the self-proclaimed Mahdi Muhammad Ahmad, who had vowed to conquer Egypt and drive out the Ottomans. The first, two-volume, edition includes accounts of Churchill's own experiences as a British Army officer during the war, and his views on its conduct.
The Battle of Atbara also known as the Battle of the Atbara River took place during the Mahdist War. Anglo-Egyptian forces defeated 15,000 Mahdists on the banks of the River Atbara. The battle proved to be the turning point in the reconquest of Sudan by the British and Egyptian coalition.
Osman Digna was a follower of Muhammad Ahmad, the self-proclaimed Mahdi, in Sudan, who became his best known military commander during the Mahdist War. He was claimed to be a descendant from the Abbasid family. As the Mahdi's ablest general, he played an important role in the fate of General Charles George Gordon and the end of Turkish-Egyptian rule in Sudan.
The Mahdist War was a war between the Mahdist Sudanese, led by Muhammad Ahmad bin Abdullah, who had proclaimed himself the "Mahdi" of Islam, and the forces of the Khedivate of Egypt, initially, and later the forces of Britain. After four years of revolt, the Mahdist rebels overthrew the Ottoman-Egyptian administration with the fall of Khartoum and gained control over Sudan. The Mahdist State launched several unsuccessful invasions of their neighbours, expanding the scale of the conflict to also include the Italian Empire, the Congo Free State and the Ethiopian Empire. They also faced significant internal rebellion. Anglo-Egyptian forces reconquered Sudan in 1898 and the Mahdist state collapsed following defeat at the battle of Omdurman. The last organised resistance from the Mahdists ended the next year, leading to the creation of Anglo-Egyptian Sudan (1899–1956), a de jure condominium of the British Empire, and the Kingdom of Egypt, in which Britain had de facto control over Sudan.
The Battle of Toski (Tushkah) was part of the Mahdist War. It took place on August 3, 1889, in southern Egypt between the Anglo-Egyptian forces and the Mahdist forces of the Sudan.
The Battle of Gallabat, also known as the Battle of Metemma, was fought on 9–10 March 1889 during the Mahdist War between the Mahdist Sudanese and Ethiopian forces. It is a critical event in Ethiopian history because Nəgusä Nägäst Yohannes IV was killed in this battle, and because it was the last major battle on the Ethiopian front of the Mahdist War. The fighting occurred at the site of the twin settlements of Gallabat and Metemma.
The Battle of Tamai took place on 13 March 1884 between a British force under Sir Gerald Graham and a Mahdist Sudanese army led by Osman Digna.
The Battle of Ferkeh occurred during the Mahdist War in which an army of Mahdists was surprised and routed by Egyptian forces, led by Sir Herbert Kitchener, on 7 June 1896. It was the first significant action of the reconquest of Sudan, which culminated in the September 1898 Battle of Omdurman.
The Battle of Embabo was fought 6 June 1882, between the Shewan forces of Negus Menelik and the Gojjame forces of Negus Tekle Haymanot. The forces fought to gain control over the Oromo areas south of the Gibe River. The Gojjame forces under Tekle Haymanot were defeated. This is one of the three battles which Donald Donham lists that led to Shewan supremacy over the rest of Ethiopia.
Hailu Tekle Haymanot, also named Hailu II of Gojjam, was an army commander and a member of the nobility of the Ethiopian Empire. He represented a provincial ruling elite who were often at odds with the Ethiopian central government. Hailu Tekle Haymanot was an independent-minded potentate who, throughout his life, was mistrustful of and mistrusted by the Emperor.
Tekle Haymanot Tesema, also known as Adal Tesema, Tekle Haymanot of Gojjam, and Tekle Haimanot of Gojjam, was King of Gojjam. He was later an army commander and a member of the nobility of the Ethiopian Empire.
The Anglo-Egyptian conquest of Sudan in 1896–1899 was a reconquest of territory lost by the Khedives of Egypt in 1884–1885 during the Mahdist War. The British had failed to organise an orderly withdrawal of the Egyptian Army from Sudan, and the defeat at Khartoum left only Suakin and Equatoria under Egyptian control after 1885. The conquest of 1896–1899 defeated and destroyed the Mahdist State and re-established Anglo-Egyptian rule, which remained until Sudan became independent in 1956.
The Italo-Ethiopian War of 1887–1889 was an undeclared war between the Kingdom of Italy and the Ethiopian Empire occurring during the Italian colonization of Eritrea. The conflict ended with a treaty of friendship, which delimited the border between Ethiopia and Italian Eritrea but contained clauses whose different interpretations led to another Italo-Ethiopian war.
The Mahdi's tomb or qubba is located in Omdurman, Sudan. It was the burial place of Muhammad Ahmad, the leader of an Islamic revolt against Turco-Egyptian Sudan in the late 19th century.
