After the Civil War, Americans had little interest in expansionism. However, in the 1890s, some Americans wanted to pursue the idea of ​​Manifest Destiny that had already inspired their ancestors when they acquired territories from Native Americans and then from Mexico. Although Americans at the turn of the 20th century were not zealous about overseas expansion, they were also aware of European imperialist designs. In fact, European powers like France, Germany, Great Britain, and Russia vied for control of foreign lands and resources. Therefore, fear of dwindling natural resources and the depression of the 1890s encouraged the business elite to seek new markets.

Additionally, the Americans waged war against Spain for control of the Philippines and Cuba.
