Beginning in 1914, WWI forced people from all over the European continent to contribute to their respective countries in many ways. Women nursed hurt soldiers, and men accepted calls to the front line. Hardly anyone escaped the conflict unscathed.
Historical photos immortalized those intense moments, and though photographers captured the images in black and white, they remain quite poignant. In some especially haunting frames, soldiers wear gas masks and stand in trenches.
Indeed, times were tumultuous, but thanks to these snapshots, no one will forget the four-year-long story any time soon.
