At its greatest extent it spanned 6,000 mi (9,700 km), covered an area of 33,000,000 km2 (12,700,000 sq mi), 22% of the Earth’s total land area, and held sway over a population of 100 million.

It was the most widespread war in history, with more than 100 million military personnel mobilized. In a state of “total war,” the major participants placed their entire economic, industrial, and scientific capabilities at the service of the war effort, erasing the distinction between civilian and military resources. Marked by significant events involving the mass death of civilians, including the Holocaust and the only use of nuclear weapons in warfare, it was the deadliest conflict in human history, resulting in 50 million to over 70 million fatalities.

The start date for WWII is inaccurate. Though 1939 was when Great Britain declared war on Germany, I’d say the Japanese invasion of Manchuria is 1931 started the war. At the latest, I’d say the war started with the 1937 Japanese invasion of China, considering the fact that fighting there took place until the end of the war and millions of Chinese people were killed.
