World War I Practice Worksheet
| # | Answer |
|---|---|
| 1 | An alliance is an agreement between countries to support and protect one another. Before World War I, alliances were important because they connected countries and made a small conflict more likely to grow into a larger war. |
| 2 | Two major causes were militarism and nationalism. Militarism meant countries were building up strong armies and weapons, which made them ready for war. Nationalism meant people felt very loyal to their own country and wanted it to be powerful, which increased tensions between nations. |
| 3 | The assassination of Archduke Franz Ferdinand was important because he was a leader of Austria-Hungary. His death caused anger and tension, and Austria-Hungary blamed Serbia. This set off a chain of events because other countries joined in to support their allies. |
| 4 | The alliance system turned a conflict between a few countries into a world war because countries promised to help their allies. When Austria-Hungary and Serbia became involved, other powerful countries such as Germany, Russia, France, and Britain were pulled into the fighting on different sides. |
| 5 | World War I changed governments by causing the collapse of some empires and the creation of new countries. It also changed life for people by bringing great loss, debt, and damage, and it led many governments to think more carefully about peace and international cooperation in the future. |
