Why is world war 1 known as modern war?

Answer 1

World War I is known as modern war primarily due to the significant advancements in technology and tactics that transformed the battlefield. Innovations such as tanks, airplanes, machine guns, and chemical weapons changed combat dynamics and led to unprecedented levels of destruction. Additionally, the scale of mobilization and the involvement of multiple nations reflected a shift toward total war, where entire societies were engaged in the conflict. This combination of technology and total war strategies marked a departure from previous military conflicts.
