What Was World War I?

描述

1914年，一位奧地利大公被暗殺，引發了一場長達四年的災難性沖突，數十個國家卷入其中，世界各地都發生了戰爭。

This compelling addition to the What Was? series covers what was supposed to be “the war to end all wars” but tragically wasn’t.

In 1914, the assassination of an Austrian archduke set off a disastrous four-year-long conflict involving dozens of countries with battles taking place in all parts of the world. World War I was the first to use planes and tanks as well as deadly gases that left soldiers blinded or “shell shocked” (a condition now called Post Traumatic Stress Syndrome).
