1. Imperial expansion:
As European powers sought to expand their empires and gain access to resources, they came into conflict with each other. For example, the British and French competed for control of Egypt and Sudan, while Russia and Austria-Hungary competed for influence in the Balkans.
2. Nationalism and imperialism:
Nationalism was on the rise in Europe during the late 19th and early 20th centuries, and this was closely tied to imperialism. Many Europeans believed that their nation was superior and should expand its empire, regardless of the cost to other nations. This sense of national pride and rivalry contributed to tensions between European powers.
3. Balance of power:
The European powers maintained a balance of power in Europe, which meant that they tried to prevent any one country from becoming too powerful. If one country became too powerful, the others would form alliances against it. This system of balance of power was constantly shifting, and it was a major factor in the outbreak of World War I.
4. Arms race:
The arms race was a competition between European powers to build up their militaries. This arms race was fueled by fears of war and by the desire to be prepared for any conflict. The arms race placed a heavy burden on the European economies and contributed to the sense of insecurity and distrust that led to war.
5. Assassination of Archduke Franz Ferdinand:
The assassination of Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, was the immediate trigger that sparked World War I. The assassination was carried out by a Serbian nationalist, and it led to a chain of events that culminated in the outbreak of war.
In summary, the rivalries between European empires were a significant cause of World War I. Imperial expansion, nationalism, the balance of power, the arms race, and the assassination of Archduke Franz Ferdinand all contributed to the outbreak of war in 1914.
