World War II was the most destructive war in history. Estimates of those killed vary from 35 million to 60 million. The total for Europe alone was 15 million to 20 million—more than twice as many as in World War I.
Table ranking "History's Most Deadly Events": Influenza pandemic (1918-19) 20-40 million deaths; black death/plague (1348-50), 20-25 million deaths, AIDS pandemic (through 2000) 21.8 million deaths, World War II (1937-45), 15.9 million deaths, and World War I (1914-18) 9.2 million deaths.
The global number of deaths per day is around 150,000 deaths. The number of deaths per day varies depending on various factors such as natural disasters, accidents, illnesses, and violence.
While larger animals like sharks or hippos may seem a likely culprit, the animal that kills the most humans per year is actually the mosquito.
The most lethal war in human history is almost certainly World War II. Other wars may have been more lethal but lack credible records. Sixty to eighty million people died between 1939 and 1945. Twenty one to twenty five million of the deaths were military, the remainder civilian.
The Soviet Union suffered the highest number of fatalities of any single nation, with estimates mostly falling between 22 and 27 million deaths. China then suffered the second greatest, at around 20 million, although these figures are less certain and often overlap with the Chinese Civil War.
The Korean War: 'The Forgotten War'
American troops were sent to support the South and by the time a ceasefire was proclaimed in 1953, over five million soldiers and civilians had died. To this day, a formal peace treaty has not been signed.
According to historian Niall Ferguson, France is the most successful military power in history.
Countries such as Afghanistan, Central African Republic, Ethiopia, Libya, Mali, Somalia, South Sudan, and Syria are all currently experiencing civil wars, resulting in significant casualties and displacement. Drug wars are another form of conflict that can result in significant violence and unrest.
World War II was a conflict that involved virtually every part of the world from 1939 to 1945. The clash was between the Axis powers, which primarily included Germany, Italy, and Japan, and the Allied powers, which included Great Britain, France, the United States, the Soviet Union, and China.
As many as 20 million people died in China, including up to 3.75 million military deaths and 18.19 million civilian deaths.
World War II began on July 7, 1937—not in Poland or at Pearl Harbor, but in China. On that date, outside of Beijing, Japanese and Chinese troops clashed, and within a few days, the local conflict had escalated to a full, though undeclared, war between China and Japan.
Australia lost 34,000 service personnel during World War II. Total battle casualties were 72,814. Over 31,000 Australian became prisoners-of-war.
Military deaths from all causes totaled 21–25 million, including deaths in captivity of about 5 million prisoners of war. More than half of the total number of casualties are accounted for by the dead of the Republic of China and of the Soviet Union.
Axis powers. The Axis powers (Nazi Germany, Fascist Italy, and Imperial Japan) were some of the most systematic perpetrators of war crimes in modern history.
The Anglo-Zanzibar War was a military conflict fought between the United Kingdom and the Zanzibar Sultanate on 27 August 1896. The conflict lasted between 38 and 45 minutes, marking it as the shortest recorded war in history.
The Civil War was the deadliest war in American history. Altogether, over 600,000 died in the conflict, more than World War I and World War II combined. A soldier was 13 times more likely to die in the Civil War than in the Vietnam War.
Most countries in the world have fought bloody wars. Conflict and war is integral part of human history. However, China, China is the country where historically most people have died due to wars. China is an ancient civilization, and it's history of it's bloody conflicts is also that ancient.

Malaria. Mosquitos are the deadliest creature in the world because they transmit a number of deadly diseases, the worst of which is malaria. Malaria is a mosquito-borne disease caused by a parasite that results in fever, chills, headache, vomiting and, if left untreated, death.
