Step-by-step explanation:
The factors leading to the outbreak of World War I (WWI) included new alliances, nationalism, militarism, Social Darwinism, and New Imperialism. The formation of new alliances, such as the Triple Entente and the Triple Alliance, created tensions between different nations. Nationalism, which emphasized loyalty and pride in one's nation, led to intense rivalries and competition between countries. Militarism, where nations built up their military strength, increased the likelihood of conflict. Social Darwinism, which applied the concepts of natural selection to societies, fueled the belief in the superiority of one's own nation. Finally, New Imperialism, the scramble for colonies and resources, heightened tensions between imperial powers. These factors collectively contributed to the outbreak of WWI.
