Final answer:
The start of World War 1 was contributed by the alliance system, nationalism, and imperialism.
Step-by-step explanation:
There were several factors that contributed to the start of World War 1:
- Alliance system: The complex network of alliances between different countries created a situation where a conflict in one region could quickly escalate into a global war. For example, the assassination of Archduke Franz Ferdinand of Austria-Hungary by a Serbian nationalist led to a chain reaction of declarations of war.
- Nationalism: The intense loyalty and pride that many people felt towards their own country exacerbated tensions between nations. In many cases, this nationalism fueled conflicts and rivalries.
- Imperialism: The competition among European powers for colonies and resources around the world created tensions and rivalries, particularly in Africa and Asia. This rivalry contributed to the overall tension in Europe and increased the likelihood of conflict.
