Achievements and Crises (1900-1945)

The first half of the 20th century was one of rapid technological advances. It was a period when the tensions between industrialized nations resulted in World War I and set the stage for World War II. While World War II transformed the balance of world power, it was the most destructive and costly war in terms of human casualties and material resources expended.
