Question: What is the term given to the period of time in which militaristic European powers increased their control of Africa from 10 to 90%?

The "Scramble for Africa" was the occupation, division, and colonisation of African territory by European powers during the period of New Imperialism, between 1881 and 1914.  It is also called the Partition of Africa and by some, the Conquest of Africa.  In 1870, only 10 percent of Africa was under European control; by 1914 it had increased to almost 90 percent of the continent, with only Ethiopia (Abyssinia), the Dervish state (present-day Somalia) and Liberia still being independent. <SEP> The occupation of the Ottoman Bank (Turkish: "Osmanlı Bankası Baskını" , "Raid on the Ottoman Bank"; Armenian: Պանք Օթօմանի գրաւումը , "Bank Otomani k'ravumĕ" "Ottoman Bank takeover") by members of the Armenian Revolutionary Federation (Dashnak Party) took place in Constantinople, the capital of the Ottoman Empire, on 26 August 1896.  In an effort to raise further awareness and action by the major European powers, 28 armed men and women led primarily by Papken Siuni and Armen Garo took over the bank which largely employed European personnel from Great Britain and France.  Stirred largely due to the inaction of the European powers in regard to mass-pogroms and massacres of Armenians instigated by the Sultan Abdul-Hamid II, the Armenian Revolutionary Federation members saw its seizure as their best attempt to bring full attention to the massacres.  The Ottoman Bank, at the time, served as an important financial center for both the Empire and the countries of Europe. <SEP> The Anglo-Portuguese Treaty of 1891 was an agreement between the United Kingdom of Great Britain and Ireland and Portugal which fixed the boundaries between the British Central Africa Protectorate, (now Malawi), and the territories administered by the British South Africa Company in Mashonaland and Matabeleland, (now parts of Zimbabwe), and North-Western Rhodesia (now part of Zambia) and Portuguese Mozambique and also between the British South Africa Company administered territories of North-Eastern Rhodesia (now in Zambia), and Portuguese Angola.  This treaty brought to an end over 20 years of increasing disagreement over conflicting territorial claims in the eastern part of Central Africa, where Portugal has long-standing claims based on prior discovery and exploration but where British citizens set up missions and embryonic trading concerns in the Shire Highlands in what is now Malawi from the 1860s.  These disagreements were increased in the 1870s and 1880s, firstly by a dispute over a British claim to part of Delagoa Bay and by the failure of bi-lateral negotiations between the two countries over the boundaries of Portuguese territories and secondly as a result of the Berlin Conference of 1884–85, which set-out the doctrine of effective occupation.  After the Berlin Conference, Portugal tried to establish a zone of effective occupation linking its colonies in Angola and Mozambique through expeditions making treaties that would establish protectorates over local peoples and obtaining recognition from other European powers.  The relative success of these Portuguese efforts alarmed the British government of Lord Salisbury, which was also under pressure from missionaries in the Shire Highlands, and also Cecil Rhodes, who founded the British South Africa Company in 1888 with the aim of controlling as much of south-central Africa as it could.  For these reasons, and in response to a minor armed conflict in the Shire Highlands, Lord Salisbury issued the 1890 British Ultimatum which required Portugal to evacuate the areas in dispute.  Lord Salisbury refused the Portuguese request for arbitration and, after an abortive attempt to fix the boundaries of their respective territories in 1890, the Anglo-Portuguese Treaty of 1891 was accepted by Portugal under duress. <SEP> Expansionist nationalism is an aggressive and radical form of nationalism that incorporates autonomous, patriotic sentiments with a belief in expansionism.  The term was coined during the late nineteenth century as European powers indulged in the 'Scramble for Africa' in the name of national glory, but has been most associated with militarist governments during the 20th century including Fascist Italy, Nazi Germany, the Japanese empire, and the Balkans countries of Albania (Greater Albania), Croatia (Greater Croatia) and Serbia (Greater Serbia).
