The invasion of Anjouan, on 25 March 2008, was an amphibious assault led by the Comoros, backed by African Union (AU) forces, including troops from Sudan, Tanzania, Senegal, along with logistical support from Libya and France. The objective of the invasion was to topple Colonel Mohamed Bacar's leadership in Anjouan, an island in the Union of Comoros, when he refused to step down after a disputed 2007 election, in defiance of the federal government and the AU. The Comoros archipelago in the Indian Ocean has had a fractious history since independence from France in 1975, experiencing more than 20 coups or attempted coups.

The First Sudanese Civil War was a conflict from 1955 to 1972 between the northern part of Sudan and the southern Sudan region that demanded representation and more regional autonomy. Half a million people died over the 17 years and the war was divided into four major stages: initial guerrilla warfare, the creation of the Anyanya insurgency, political strife within the government and establishment of the South Sudan Liberation Movement.

The Heglig Crisis was a brief war fought between the countries of Sudan and South Sudan in 2012 over oil-rich regions between South Sudan's Unity and Sudan's South Kordofan states.

Small-scale clashes continued until an agreement on borders and natural resources was signed on 26 September, resolving most aspects of the conflict.

The Lord's Resistance Army insurgency is an ongoing guerrilla campaign waged by the Lord's Resistance Army (LRA) insurgent group since 1987. Currently, there is low-level LRA activity in eastern Democratic Republic of the Congo and the Central African Republic. The movement is led by Joseph Kony, who proclaims himself the "spokesperson" of God and a spirit medium. It aims to overthrow Yoweri Museveni's Ugandan government and establish a theocratic state based on the Ten Commandments and Acholi tradition.

The Mahdist War was a war of the late 19th century between the Mahdist Sudanese of the religious leader Muhammad Ahmad bin Abd Allah, who had proclaimed himself the "Mahdi" of Islam, and the forces of the Khedivate of Egypt, initially, and later the forces of Britain. Eighteen years of war resulted in the nominally joint-rule state of the 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 the Sudan. The Sudanese launched several unsuccessful invasions of their neighbours, expanding the scale of the conflict to include not only Britain and Egypt but the Italian Empire, the Congo Free State and the Ethiopian Empire.

Operations on the Northern front, East Africa, 1940 in the Second World War, were conducted by the British in Sudan and the Armed Forces Command of Italian East Africa in Eritrea and Ethiopia. On 1 June 1940, Amedeo, Duke of Aosta the Viceroy and Governor-General of the Africa Orientale Italiana, commander in chief of the Armed Forces Command of the Royal Italian Army and General of the Air Force, had about 290,476 local and metropolitan troops and by 1 August, mobilisation had increased the number to 371,053 troops.

The Second Sudanese Civil War was a conflict from 1983 to 2005 between the central Sudanese government and the Sudan People's Liberation Army. It was largely a continuation of the First Sudanese Civil War of 1955 to 1972. Although it originated in southern Sudan, the civil war spread to the Nuba mountains and the Blue Nile. It lasted for 22 years and is one of the longest civil wars on record. The war resulted in the independence of South Sudan six years after the war ended.

The Simba rebellion of 1963–65, also known as the Orientale Revolt, was a rebellion in the Democratic Republic of the Congo which took place within the wider context of the Congo Crisis and the Cold War. The rebellion, located in the east of the country, was led by the followers of Patrice Lumumba, who had been ousted from power in 1960 by Joseph Kasa-Vubu and Joseph-Désiré Mobutu and subsequently killed in January 1961 in Katanga. The rebellion was contemporaneous with the Kwilu Rebellion led by fellow Lumumbist Pierre Mulele in central Congo.

The Sudanese conflict in South Kordofan and Blue Nile is an armed conflict in the Sudanese southern states of South Kordofan and Blue Nile between the Sudanese Army (SAF) and Sudan People's Liberation Movement-North (SPLM-N), a northern affiliate of the Sudan People's Liberation Movement (SPLM) in South Sudan. After some years of relative calm following the 2005 agreement which ended the second Sudanese civil war between the Sudanese government and SPLM rebels, fighting broke out again in the lead-up to South Sudan independence on 9 July 2011, starting in South Kordofan on 5 June and spreading to the neighboring Blue Nile state in September. SPLM-N, splitting from newly independent SPLM, took up arms against the inclusion of the two southern states in Sudan with no popular consultation and against the lack of democratic elections. The conflict is intertwined with the War in Darfur, since in November 2011 SPLM-N established a loose alliance with Darfuri rebels, called Sudan Revolutionary Front (SRF).

Sudanese nomadic conflicts are non-state conflicts between rival nomadic tribes taking place in the territory of Sudan and, since 2011, South Sudan. Conflict between nomadic tribes in Sudan is common, with fights breaking out over scarce resources, including grazing land, cattle and drinking water. Some of the tribes involved in these clashes have been the Messiria, Maalia, Rizeigat and Bani Hussein Arabic tribes inhabiting Darfur and West Kordofan, and the Dinka, Nuer and Murle African ethnic groups inhabiting South Sudan. Conflicts have been fueled by other major wars taking place in the same regions, in particular the Second Sudanese Civil War, the War in Darfur and the Sudanese conflict in South Kordofan and Blue Nile.

The Wad Habuba Revolt was an uprising in Anglo-Egyptian Sudan in mid-1908. Its causes laid in religious opposition to Christian British rule in Sudan, and a desire to restore the Mahdist State. It was led by a veteran of the Mahdist War, Abd al-Qadir Muhammad Imam Wad Habuba. It began in April, when al-Qadir took over the town of Tugur with 40 followers. From there, the rebellion spread to Katfia. Colonial authorities took the revolt very seriously and dispatched 2 infantry companies to quell the uprising. By the end of April, Katfia had been bloodlessly recaptured. On the night of 2 May, the rebels attempted to retake Katfia from the British, but were unsuccessful, and suffered 35 killed in this battle, while the British forces, led by Ernest Arthur Dickinson suffered 17 killed and wounded. By 3 May, the revolt had ended and al-Qadir had left for Omdurman on a donkey.

World War I was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. Contemporaneously known as the Great War or "the war to end all wars", it led to the mobilisation of more than 70 million military personnel, including 60 million Europeans, making it one of the largest wars in history. It is also one of the deadliest conflicts in history, with an estimated nine million combatant deaths and 13 million civilian deaths as a direct result of the war, while resulting genocides and the related 1918 Spanish flu pandemic caused another 17–100 million deaths worldwide, including an estimated 2.64 million Spanish flu deaths in Europe and as many as 675,000 Spanish flu deaths in the United States.
