Explain how World War I was fought (total war, new technology, trench warfare) and its consequences: massive casualties, the fall of empires, the Treaty of Versailles, and the conditions that led to future conflict (Framework Key Idea 10.6).

What this topic is asking

Framework Key Idea 10.6 asks you to explain how World War I was fought (as a total war with deadly new technology and trench warfare) and its consequences: enormous casualties, the fall of empires, the Treaty of Versailles, and the conditions that led toward future conflict. The consequences are a major turning-point and cause-and-effect topic, because they lead straight into the interwar period and World War II.

How the war was fought

World War I was the first true total war. Governments directed factories to make weapons, rationed food, recruited millions of soldiers, employed women in war work, and used propaganda to sustain support. The fighting was made horrific by new technology: machine guns mowed down advancing troops, poison gas choked soldiers, and tanks, airplanes, and submarines appeared. On the Western Front the result was trench warfare, two lines of trenches facing each other across "no man's land", where attacks gained little ground at the cost of staggering casualties. The United States entered the war in 1917 (after German submarine attacks and the Zimmermann Telegram), tipping the balance toward the Allies, who won in November 1918.

The consequences

Why the consequences mattered

The peace settlement is one of the great turning points of the modern era. The Treaty of Versailles left Germany humiliated, resentful, and economically strained, conditions that Adolf Hitler and the Nazis would later exploit. The collapse of empires created unstable new states and unresolved nationalist tensions. The war also shattered faith in progress and left a generation traumatized. In short, the way World War I ended helped cause World War II twenty years later, which is exactly the cause-and-effect link the exam wants.

Try this

Q1. Name two new technologies that made World War I so deadly. [Recall]

• Cue. Any two of: machine guns, poison gas, tanks, airplanes, submarines.

Q2. Explain why the Treaty of Versailles is seen as a cause of World War II. [Short explanation]

• Cue. Its harsh terms (war-guilt clause, reparations, lost territory, disarmament) humiliated and impoverished Germany, creating resentment that Hitler and the Nazis exploited to gain power and pursue another war.
