What were the major causes of World War I and how did it impact Turkey?

World War I, which lasted from 1914 to 1918, was one of the deadliest conflicts in human history, and had a profound impact on the world. The major causes of the war include nationalism, imperialism, militarism, and the complex system of alliances that existed between the major powers of Europe.

The war began with the assassination of Archduke Franz Ferdinand of Austria-Hungary by a Serbian nationalist in June 1914, which led to a chain reaction of events that ultimately drew in most of Europe's major powers.

Turkey, which was then part of the Ottoman Empire, entered the war on the side of Germany and Austria-Hungary in November 1914. The war had a devastating impact on Turkey, as it suffered heavy losses on the battlefield and its economy was severely disrupted. Additionally, the war contributed to the collapse of the Ottoman Empire, which was dissolved in the aftermath of the conflict.

As a result of the war, the political and social order of Europe was drastically changed, and the stage was set for the emergence of new world powers and the rise of ideologies such as fascism and communism. The war also had a lasting impact on international relations, as it led to the establishment of the League of Nations, an organization designed to promote peace and prevent future conflicts.
