Final answer:
Between 1884 and the 1950's, Britain, France, Belgium, and Germany were the main European nations dominating Africa, following the Scramble for Africa which was formalized by the Berlin Conference.
Step-by-step explanation:
During the late 19th century and the first half of the 20th century, several European nations established their dominance over most of Africa. The Berlin Conference of 1884-1885 was pivotal in this context, as it marked the start of the Scramble for Africa. The major colonial powers included Britain, France, Belgium, and Germany. Other colonial powers such as Portugal and Spain maintained colonies from earlier centuries.
Primary motivations for colonization included the search for raw materials, new markets for goods, international prestige, national pride, and military superiority. Technological advancements like steamships, quinine for malaria, and improved weaponry gave Europeans an edge over African resistances. By 1900, around 90% of Africa was under European control, with only Ethiopia and Liberia maintaining independence.
Post-World War II saw the rise of anti-colonial movements, and many African nations gained independence in the 1950's and 1960's, marking the end of European colonial rule in Africa.
