In honor of World War I's centennial this year, The Open University has "colorized" a sample of select photos from the conflict with the help of a photograph restoration expert.
The photos, which were originally in black and white, feel jarringly current when colorized. World War I began 100 years ago, but these photos remind us one of the worst and seemingly most inexplicable conflicts in history isn't quite as far off as it might seem.
The conflict, which killed over nine million people and affected almost ever corner of the globe, began on July 28, 1914. Thought of as the "war to end all wars," World War I marked a number of firsts in military conflict, including the use of planes, tanks, and chemical weapons.
