The MAIN causes of the First World War are often summarised
by the acronym "MAIN," which stands for Militarism, Alliances,
Imperialism, and Nationalism. These interconnected factors
contributed to the outbreak of the war in 1914:
Militarism: The arms race and militarization of European
powers in the late 19th and early 20th centuries created a
volatile environment conducive to conflict. European nations
invested heavily in military technologies and expanded their
armies and navies, leading to heightened tensions and a sense
of competition for military supremacy.
Alliances: The system of alliances that formed in Europe prior
to the war contributed to its escalation into a global conflict. The
two main alliance blocs were the Triple Entente (comprising
France, Russia, and Britain) and the Triple Alliance (comprising
Germany, Austria-Hungary, and Italy). These alliances created
a delicate balance of power in Europe and meant that any
conflict between two nations could quickly escalate into a
broader war involving multiple powers.
Imperialism: Imperial competition and the scramble for
colonies and resources exacerbated tensions between
European powers. The competition for overseas territories and
spheres of influence fueled rivalries and conflicts, particularly in
Africa, the Balkans, and the Middle East. Imperial ambitions
contributed to the complex web of alliances and entanglements
that characterised the pre-war period.
Nationalism: Nationalism, characterised by pride in one's
nation and aspirations for self-determination, played a
significant role in the outbreak of war. Nationalist sentiment
fueled rivalries between ethnic and nationalist groups within
