    • The war used many new weapons such as chemical weapons (poison gas, mustard gas) and machine guns

    • The war used a new style of combat called trench warfare → Soldiers would hide in dirty trenches and occasionally peek out to shoot → War took a long time and was a stalemate for so long → Massive casualties & long battles

​​

  • In each nation, governments mobilized their economies for the war effort and also created propaganda to boost nationalism and pro-war spirit

    • Nations imposed mandatory production quotas and encouraged women to join the industrial workforce to produce weapons and other war supplies
