  • Mahdist War

    1881–1899

    The Mahdist War (1881–1899) was a colonial conflict between the Mahdist Sudanese, led by Muhammad Ahmad who proclaimed himself the Mahdi, and the forces of Egypt and later Britain. Beginning in 1881, the Mahdists overthrew Egyptian rule in Sudan and established a Mahdist state. The British later joined the conflict alongside Egypt, eventually defeating the Mahdists. The war involved other powers such as Italy, the Congo Free State, Ethiopia, and France, and was marked by internal rebellions and famine.

  • French conquest of Algeria

    1830–1904Algiers, Algeria

    Between 1830 and 1904, France launched a military invasion and prolonged war of conquest in Algeria. In June 1830, French forces landed near Algiers, quickly seizing the capital and coastal areas. Over the following decades, despite internal political strife, France repeatedly reinforced its military presence to suppress resistance in the interior, gradually extending control southward into the Sahara, and finalizing its colonial borders by 1904.

South Asia

  • Outbreak of the Aceh War

    1873–1904

    In early 1873, discussions between representatives of the Aceh Sultanate and the United States in Singapore provoked the Netherlands, leading to a Dutch military attack on Aceh and the start of the Aceh War. The conflict was part of a series of late 19th-century wars that consolidated Dutch rule over modern-day Indonesia, ultimately ending in 1904 with the Dutch annexation of Aceh and control over the entire Indonesian archipelago. The war lasted over three decades, resulting in around 4,000 Dutch and 25,000 Acehnese deaths.
