Imperialism: The competition for colonies and resources among European powers led to conflicts and tensions between nations. Each country wanted to expand and establish colonies, resulting in territorial disputes and rivalries.

Nationalism: Nationalistic feelings and desire for self-determination fueled tensions between different ethnic and national groups. This led to the rise of independence movements and power struggles within empires, ultimately contributing to the outbreak of war.

Militarism: The arms race between major powers, particularly Germany and Britain, increased tensions and created a sense of distrust and insecurity. The build-up of military forces and the development of new technologies heightened the risk of conflict.

Alliance System: The system of alliances that had been formed by various nations in Europe increased the likelihood of a widespread conflict. The complex network of treaties and agreements meant that a dispute between two countries could quickly escalate into a full-scale war involving multiple nations.
