By 1916, World War I had changed into something much larger than a battlefield conflict.

In Episode 4 of Moments That Shape Us, the focus shifts from the trenches to the home front, where entire nations became part of the war effort. Governments took control of industries, economies were redirected toward production, and civilians were asked to support the war through rationing, labor, and propaganda.

This episode also examines two of the deadliest battles of the war, including Battle of Verdun and Battle of the Somme, where massive losses resulted in very little movement on the front lines. These battles revealed the true scale and cost of modern industrial warfare.

As the war expanded beyond soldiers and into everyday life, it became clear that this was no longer a limited conflict. It was a total war, involving entire societies and demanding everything they could give.
