The broad cause of the Spanish-American War can be attributed to manifest destiny and domestic economic interests. During the late 19th century, the prevailing ideology of manifest destiny fueled the belief that the United States was destined to expand its territory and influence across the globe. This mindset encouraged American intervention in international conflicts, particularly those in the Western Hemisphere.

Additionally, domestic economic interests played a significant role in the escalation towards war. The U.S. was keenly interested in expanding trade markets and securing economic opportunities in Cuba and other parts of the Caribbean, where American investments in sugar and other resources were substantial. The economic instability in Cuba, particularly due to its struggles against Spanish colonial rule, attracted American attention. Many Americans saw the possibility of intervention not only as a means to liberate oppressed populations but also as a way to solidify U.S. economic interests in the region.

These factors collectively fostered a climate ripe for conflict, leading to the U.S. involvement in the Spanish-American War as a demonstration of its growing power and commitment to its economic and territorial aspirations.
