World War I: The "Great War"

From August 1914 to November 1918, an unprecedented catastrophe gripped the world that continues to reverberate into our own time. World War I was touched off by a terrorist act in Bosnia and all too quickly expanded far beyond the expectations of those who were involved to become the first "total war"—the first conflict involving entire societies mobilized to wage unrestrained war, devoting all their wealth, industries, institutions, and the lives of their citizens to win victory at any price. The cost was ghastly: Altogether, at least nine million soldiers died. Twenty million were wounded, seven million of them permanently disabled. Some estimates put the civilian deaths at almost six million. And countless survivors suffered from psychological trauma for decades after. The world itself would never be the same.
