To understand why the United States sought to become a world power in the 1890s, we need to look at the historical context of that time. The late 19th century, known as the "Age of Imperialism," was a period when powerful European nations sought to extend their influence and control over territories around the world. The United States, eager to compete, also desired to assert itself on the global stage for several reasons:

1. Economic Expansion: The Industrial Revolution had transformed the United States into a major industrial and economic power. However, with a growing population and industrial capacity, the country needed new markets to sell its goods and access to raw materials. By establishing a global presence, the U.S. could secure favorable trade agreements, open new markets, and expand its economic influence.

2. National Security: As the U.S. economy grew, so did its need for resources such as oil, minerals, and strategic military bases. By expanding its territories, the United States aimed to secure these resources and create a buffer zone for national defense. Additionally, having a strong navy and overseas territories would enhance its ability to project power and protect its interests abroad.

3. Ideological Motivation: Some Americans believed in the concept of "Manifest Destiny," the idea that it was their nation's destiny to expand its territory and spread democracy and American values. This ideology fueled the desire to project American influence globally and promote democratic principles.

4. Military Strategy: As European powers colonized other regions, the United States felt pressured to establish its own presence to prevent being excluded from emerging global conflicts. By acquiring territories strategically, the U.S. could establish coaling stations, naval bases, and military outposts, thereby enhancing its military capabilities and global reach.

It is important to note that these motivations were not universally shared among Americans, and debates over imperialism and its consequences were prevalent at the time. Nonetheless, these factors collectively contributed to the United States' pursuit of becoming a world power in the 1890s.
