What does M.A.I.N.S mean for the causes of World War 1?

M.A.I.N.S is an acronym representing the four main causes of World War I: Militarism, Alliances, Imperialism, and Nationalism. Militarism refers to the arms race and military buildup among European powers. Alliances involved complex agreements between nations that created a web of obligations, leading to widespread conflict. Imperialism and Nationalism fostered competition and rivalries, as countries sought to expand their empires and assert their national identities, ultimately contributing to the outbreak of war in 1914.
