The fall of the Ottoman Empire refers to the gradual decline and eventual disintegration of one of history's most powerful empires, culminating in its official dissolution after World War I in 1922. This decline was marked by a series of military defeats, territorial losses, and the rise of nationalist movements, especially within its Arab provinces, which sought independence from Ottoman rule. The consequences of this fall had profound effects on the political landscape of the Middle East and set the stage for new nation-states and conflicts in the region.
