Final answer:
During New Imperialism, Europeans primarily established colonies in Africa and India, with Africa nearly wholly controlled and India under significant British influence.
Step-by-step explanation:
During the era of New Imperialism, European powers primarily established colonies in two key regions: Africa and India. The 'Scramble for Africa' led to the near-total control of the continent by various European countries. Britain, seeking precious resources, expanded its influence into Asia, with significant control over India after the dissolution of the Mughal Empire and the establishment of the British Raj.
France focused its colonial efforts in Southeast Asia and established a stronghold in what became known as French Indochina. While other regions like South America experienced economic imperialism and Japan was involved in the process as an imperial power (particularly in Korea), the two primary areas of European colonization during New Imperialism were indeed Africa and India.
