Militarism – Countries were building huge armies and weapons. Alliances – Agreements among competing nations to help each other if war broke out. Imperialism – Race for empires and opening up new markets. Nationalism – Intense national loyalty. People wanted independence from empires and creation of their own states.

The assassin was Gavrilo Princip, a Serbian nationalist, and a member of the terrorist organization “The Black Hand.”

Soldiers fought from 2 lines of trenches or ditches. The trenches reached from the English Channel to Switzerland. Eventually, the 2 sides reached a stalemate which lasted until 1917.
