Imperialism of Africa generally had some economic benefits, but it led to slavery and mistreatment of the native people of Africa. Governing powers competed with their neighbors to gain control of weaker nations at the expense of the natives. .
Japan's government was largely run and controlled by its army in the early 1930's, which fueled by imperialist ideas. Imperialistic movements within Japan led to the taking of control of other regions, which only supported Japanese pride and unity as a nation. The imperialist nation wanted to seize ownership from European colonies that had settled in Southeast Asia to increase its own economic benefits. The Japanese deceived Asians into taking their viewpoint by arguing that Japanese control would introduce freedom to the Asian people. This lie was exposed when the senseless killing and rape of the residents of Nanking took place. Japan's army invaded Southeast Asia in attempt to gain control of land and resources, eventually leading to the mass murder of the Chinese people. Corrupt political and military parties are held accountable for these atrocities.
Nationalism is a nation's pride in its culture, language, and history. Patriotism is just a sliver of what extreme nationalism represents. When a nation adopts nationalism it can take a variety of forms. "It can drive a state into expansionist military conflicts in an attempt to increase the nation's power or to bring within the nation's borders national groups living outside. Nationalism can also lead to persecution or, at its extreme, genocide of ethnic minorities". (Derbyshire, web) The success of nations that had colonized African countries had brought a sense of pride to these European colonies. The economic success and expansion of property had also given these European nations a sense of superiority. It also gave nations a sense of unity and safety; belonging to a group that represented its culture.
