Nationalism played a significant role in bringing about World War I by fostering a sense of pride and superiority among the nations involved. People were intensely proud of their countries and sought to assert their nation's power and influence over others. This often led to heightened tensions and rivalries, as countries pursued aggressive policies to demonstrate their strength and superiority. Nationalist sentiments also fueled competition for colonies, military power, and economic dominance, which increased hostilities. Additionally, ethnic nationalism contributed to internal strife within empires, leading to calls for independence and self-determination. The combination of national pride and resentment toward rival nations created an environment ripe for conflict, ultimately contributing to the outbreak of the war.
