The reconstruction of Germany was a long process. After World War II, Germany suffered heavy losses: the country's cities were severely damaged from the heavy bombings by the French and Polish armies, as well as the allied airlifts attempting to help retake the German cities, agricultural production was only 35% of what it was before the war. During the war, 10.3 million Germans had been killed, roughly 11 percent of the population (see also World War II casualties).
