European Imperialism was an ideology and a foreign policy of expansionism carried out by different European powers since the 16th century until the beginning of the 20th century. In this process, European powers did not oppose to enslavement, on the contrary, they created slaves trade networks to supply their colonies in the Americas with force of labor taken from Western Africa.
At the end of the 19th century, the new imperialism was characterized by an unprecedented and aggressive competition for the acquisition of overseas territories accompanied by the emergence in the colonizing countries of doctrines of racial superiority that denied the ability of subjugated peoples to govern themselves. Around 1880, most of Africa was still unoccupied by the Western powers and that continent became the main objective of the “new” imperialist expansion, giving rise to the so-called “repartition of Africa.” For this reason, from the imperial powers point of view, the European, Western, white, and Christian civilization was seen as superior to the rest.
The European presence in Southeast Asia was carried out mainly by the French, the Dutch, and the Spanish empires, while the British empire was confined to some territories known as the Straits Settlements controlled by the British East India Company. The British presence in this region was not significant enough to spread the English language.
