Which of the following empires was dissolved as a result of World War I?

The Austro-Hungarian Empire was dissolved as a direct result of World War I due to a combination of military defeat, nationalist movements, and the subsequent peace treaties that reshaped the map of Europe. Following the end of the war in 1918, the empire faced internal strife as various ethnic groups sought independence. This culminated in the empire’s official dissolution, leading to the establishment of several new nation-states, including Austria and Hungary, among others.

In contrast, the other empires mentioned—such as the British Empire, French Empire, and Spanish Empire—did not experience dissolution during or as a result of World War I. Instead, while they lost some colonies or faced challenges, they continued to exist in various forms post-war. The British and French empires actually expanded in some areas despite the war, while the Spanish Empire remained intact, particularly in its colonies in Latin America and the Philippines. Thus, the Austro-Hungarian Empire stands out as the empire significantly affected by the outcomes of World War I, leading to its complete disintegration.
