Final answer:
World War I was different from previous wars because of its use of advanced weapons and technology, its global scale, and its lasting impact on the world.
Step-by-step explanation:
World War I, also known as the Great War, was different from previous wars in several ways. Firstly, it was the first industrialized war, making use of advanced weapons and technology from the Industrial Revolution. This included weapons like tanks, airplanes, machine guns, and poison gas, which greatly increased the scale and devastation of the conflict. Secondly, it was considered the first truly global war because it was fought on multiple fronts and involved nations from nearly every continent. This meant that the war affected daily life for citizens in ways never seen before, as entire nations had to participate and endure the hardships of war. The widespread use of colonial troops also brought people from different parts of the world together, playing out against the backdrop of the war. Lastly, the war had a lasting impact on the world, leading to significant changes in national boundaries and the shift of hegemony from Western Europe to the Soviet Union and the United States.
