1917 brought with it tremendous change in the war, and in society itself.

After devastating defeats and growing opposition in the form of riots and strikes, Tsar Nicholas II of Russia was forced to abdicate and a series of revolutions followed. Germany had entered the Great War with the expectation of a short conflict and a decisive victory, but the Western Front came to a stalemate and the German army suffered devastating casualties, low morale and a lack of supplies - leading some fighting men to rebel. France, similarly fatigued with war, dealt with its own mutinies. Revolt rocked the remains of the Ottoman Empire. And opposition to war itself led many conscientious objectors in all nations to refuse to fight.

The war was the beginning of the end for many empires and ushered in a new world, though at a high cost.
