Technological development in the first half of the 20th century, waves of new imperialism and industrialization, and global conflicts, including World War I and World War II, created ways to promote further interaction and conflict. Global Environment From 1900 to 1945, the relationship between West (North America and Europe) and Africa was based on early colonialism, and the relationship between West and Latin America was still based on economics rather than politics It was still small. The relationship between west and Asia has changed as more and more intense.
Early in the 20th century, American imperialism was adequate as global industrial power and society needed to comply with social Darwinism. However, the first amendment goes further than university entrance
In the 20th century, there was a serious political change in technology and leadership. Treatment of the 20th century as a "century of America" may be a bit exaggerable, but the rise of America as a superpower is enough to quickly and dramatically justify it as it is exaggerated. It is based on a large increase in natural resources and ensures productivity gains through extensive industrialization. And the success of the United States which achieved this goal has been proved and proved in two world wars. In these wars, technical leadership was handed over from the UK and European countries to the United States. This is not to say that the fountain of European innovation has run out. From that, many important inventions of the 20th century were born.
New imperialism: European power from the late 19th century to the early 20th century, and expansion of the American and Japanese empires during the colonial period. This period is known for its unprecedented pursuit of the acquisition of overseas territory. At that time, the state promised to build their empires through the advancement and development of new technologies, conquer their territory, and utilize their resources. The new wave of imperialism reflects the ongoing conflict between the great powers, the economic desire for new resources and markets, and the spirit of "civilized mission".
