What were the six basic causes of World War 1?

The six basic causes of World War I were militarism, alliances, Imperialism, nationalism, crises in the Balkans, and the assassination of Archduke Franz Ferdinand. Militarism involved the arms race and the glorification of military power. Alliances created complex treaties that entangled multiple nations in conflict. Imperialism fueled competition for colonies, while nationalism stirred tensions among ethnic groups, particularly in the Balkans, ultimately leading to the assassination of the Archduke, which triggered the war.
