What was the number of people who participated in the Second World War?

In World War II, there were about 7 million people who died directly from war and war-related reasons (such as disasters caused by war, famine, lack of medical care, spread of infectious diseases, conscription, labor recruitment, slaughter, etc.) (about two-thirds of the battlefields in Europe and Africa, and one-third of those who died in Europe and Africa died in Nazi concentration camps or were massacred by Nazi firing squads, accounting for deliberate slaughter in World War II. Among them, 26.6 million people died in the Soviet Union (from 1941 to 1945, soldiers accounted for 35%, and the number of casualties caused by war in the Soviet Union was extremely huge, and the cumulative number of casualties among registered soldiers alone was as high as more than 18.3 million), and about 18.5 million people died in China (from 1937 to 1945, soldiers accounted for about 15%, and the cumulative number of casualties caused by war was about 16 million. However, World War II was not the war with the largest number of deaths in history. The war with the largest number of deaths in history was the Mongolian expansion war in the 13th century, which can be called the real World War I. Its battlefield covered Europe and Asia, covering an area of 25 million square kilometers, causing hundreds of millions of deaths. Only in China, The population dropped from more than 11 million before the war to 5 million after the war (population reduction and death are not the same concept, because it has offset the birth population, so the actual number of abnormal deaths is much larger than the population reduction), including 7.68 million in the Central Plains to 87,, and 12.67 million in the South to 9 million, when the world population was only about 4 million. The war spread over a wide area, causing heavy losses of life and property. Not only the First World War was hard to compare with it, but even the Second World War was dwarfed. The invention of cameras, cameras and other machines witnessed the tragic two world wars, while the bloodiness and brutality of the Mongolian war 7 years ago could only be tasted in black and white. But in any case, war will always be the nightmare of ordinary people, and I hope there will be no more war in the world.
