/kloc-which event at the end of 0/9 has a direct causal relationship with the rise of the United States?

/kloc-at the end of 0/9 and the beginning of the 20th century, the United States began to become stronger. Even at the beginning of the 20th century, the United States surpassed the established capitalist powers such as Britain and France in some aspects. What makes America strong in this era? I think there are two main reasons: social economy and physical geography.

The reasons of social economy and physical geography are interactive and contribute to the strength of the United States. Socio-economic reasons include social system, political and economic system, industrial revolution and various policies and socio-economic environment of economic development. Physical geography is the geographical position, land and resources of the United States.

Socioeconomic reasons. After the War of Independence, the United States embarked on the road of developing capitalism and gradually established and improved the capitalist system. Later, the American Civil War further cleared the obstacles to the development of American capitalism. The American Civil War was the second bourgeois revolution in America. Industrial and commercial capitalism in the north won the civil war and abolished slavery. During the reconstruction period, after the democratic transformation in the south, the American economy developed rapidly on the basis of more single capitalism. The American Civil War promoted the unification of American countries, and at the same time formed a unified domestic market, which greatly promoted the later economic development of the United States, and at the same time, the strong national strength also provided a solid backing for economic development.

/kloc-in the middle and late of the 0/9th century, the second industrial revolution began and gradually developed in depth, and the United States seized this opportunity well. During the second industrial revolution, the United States applied a lot of new science and technology in economic production, which effectively promoted economic development. During this period, the United States plundered a large number of overseas resources, vigorously expanded overseas capital markets and accelerated economic development. By the end of 19, due to the in-depth development of the second industrial revolution, major capitalist countries have successively entered the stage of imperialism, and liberal capitalism has developed into monopoly capitalism. During this period, the United States also entered the stage of imperialism, forming monopoly production forms such as trusts. The concentration of bank capital in the United States is relatively high, and the combination of bank capital and industrial capital forms financial capital and financial oligarchy. The monopoly bourgeoisie in the United States also manipulated the country's economic lifeline and affected the country's political life. On this basis, the United States has become a typical trust imperialism. After independence, the United States embarked on the road of large-scale territorial expansion. After a long period of development, by the end of 19, the United States had become a big agricultural country, and the development of agriculture provided raw materials and promoted the development of industry. The capitalist mode of production has external expansion, and the United States has carried out long-term unique American-style economic construction under the capitalist mode of production, which contributed to the strength of the United States in this period.

After the American War of Independence, after a long period of political construction, a relatively democratic political system was formed. These systems minimize and avoid the losses caused by the mistakes of state leaders, and ensure and implement the full enjoyment of civil rights by every citizen to the greatest extent. This system has also attracted elites and outstanding figures from all over the world to serve it. The two-party system implemented in the United States has played a role in easing contradictions and protecting the monopoly bourgeoisie. A good political environment provides conditions for the healthy development of economy.

The United States has always attached great importance to scientific and technological inventions and the development of education. Science and technology are the primary productive forces, and the development of science and technology in the United States has promoted the rapid development of productive forces. The development of education has improved the quality of citizens, promoted the research and development of science and technology, and provided the guarantee of talents and technology for the strength of the United States.

American politics is relatively democratic, which makes domestic political situation relatively stable. Since President Washington, the United States has always had isolationism. The United States is unwilling to interfere in the affairs between European countries and is unwilling to pay attention to the wars of European countries. 19 At the end of the 20th century, European countries were constantly at war, and the United States stayed out of it, with relatively few wars and relatively stable society. The relative stability of American social and political environment provides a good environment for economic development and is conducive to the construction of American economy. At the same time, the relatively stable social and political environment in the United States has attracted a large number of immigrants. The influx of European immigrants has brought a lot of money, advanced production technology and advanced production tools to the United States. The influx of Asian and African immigrants has brought sufficient labor to the United States and promoted the development of wasteland in the United States. In a word, the influx of immigrants has injected new vitality into the development of American economy.

Natural geographical reasons. The United States has a unique geographical location. The long-term territorial expansion after the independence of the United States has greatly expanded the territory of the United States. At the same time, the expansion of land area has increased the natural resources of the United States and provided a broader place for industrial and agricultural production. Land resources provide conditions for agricultural development. But also provides abundant raw materials for industrial production. The unique geographical location of the United States, far from Europe, makes it far from the right and wrong of Europe, thus giving the United States better external conditions. The good natural conditions in the United States have promoted the economic construction of the United States and provided objective conditions for its strength.

In a word, the interaction of good socio-economic conditions and natural geographical environment made the United States strong at the end of 19 and the beginning of the 20th century inevitable. Among them, the main reason why the United States was strong during this period was its long-term economic construction in a good environment.
