Final answer:
In the late 1880s, the percentage of Africa controlled by Europe had significantly increased from 10% to around 90%, marking the peak of the 'Scramble for Africa' where European powers aggressively colonized the continent irrespective of the endemic societies.
Step-by-step explanation:
In the late 1880s, the percentage of Africa under European control increased dramatically from roughly 10% in 1876 to about 90% by 1900. This expansion was a result of the Second Industrial Revolution, during which European nations sought access to raw materials and new markets. The period is referred to as the "Scramble for Africa", characterized by heightened colonization efforts and competition among European powers.
Notable events like the Berlin Conference of 1884 solidified European claims to African territory, disregarding the autonomy and presence of native African societies and kingdoms. Britain, France, Belgium, and Germany were among the largest colonial powers, and the majority of Africa's modern borders trace back to the decisions made during this time of aggressive European imperialism.
