Answer:
There is no single country that can be said to be solely responsible for starting World War I, as the causes of the war were complex and have been the subject of much historical debate. Some historians argue that Germany, led by Kaiser Wilhelm II, was the primary instigator of the conflict, while others point to the actions of other European powers, such as Russia, Austria-Hungary and Serbia, as contributing factors. Ultimately, it was a confluence of interlocking alliances, territorial disputes, and imperialism, as well as the actions of individual political leaders, that led to the outbreak of war in 1914.
