The term "World War I" is often used interchangeably with the "First World War", as they both refer to the global conflict that lasted from 1914 to 1918. Other common synonyms for this war include the "Great War", the "War to End All Wars", and the "European War". Some historians refer to this conflict as the "Imperial War" because it involved the major colonial powers of Europe. In Russia, it is known as the "Eastern Front", while in Japan, it is called the "Taishō Period's Europe War". Regardless of the synonym used, World War I had a profound impact on the world and reshaped the political and economic landscape of Europe.
