Mankind has been involved in wars since their very existence on earth. These wars were fought for controlling the resources, extending one’s territory or control and domination over others. Seen in a broader perspective, all wars have been caused due to greed and hunger for power. It must have started from small groups of people in a settlement or village and extended to rivalries among tribes.
As the humans progressed, their sphere of influence widened and so have been the scope and territories of war. Humans have already witnessed the horrors of two world wars where millions of people from several countries lost their lives in meaningless wars which have scarred the humanity forever. Yet man has not learned his lesson. A third world war with stockpiles of nuclear arsenals has the potential to destroy all humanity several times over. It will make humankind on planet earth, extinct forever.
The following is a list of the 11 bloodiest wars in the history of mankind. These are listed by the death tolls. These deaths are not necessarily of only the army and military those were directly involved in the war, but also includes civilian casualty. Civilian deaths were also caused due to the outcomes of the wars such as famine, epidemics, diseases, atrocities and anything that contributed to these deaths.
Here are the top 11 Deadliest Wars In Human History

His military campaigns are estimated by some scholars to have caused the deaths of 17 million people. This is about 5% of the total population of the world at that time. This also means it must be at least 10% of the population in Asia and nearby regions. He was the great-great-great-grandfather of Babur (1483-1530). Babur was the founder of the Mughal Empire in India. The Mughals ruled India and nearby for over three centuries, from 1526 to 1857.

8. Spanish Conquest of Mexico, 1519 to 1632, 24.5 million deaths
The Spanish conquest of the Aztec Empire is one of the bloodiest wars in human history and amounted to what can now be called genocide.

They captured the Aztec emperor Moctezuma and Tenochtitlan, the capital of the Aztec Empire. The Spaniards allowed a massive Aztec feast to be celebrated in Tenochtitlan. Then just like the earlier massacre in Cholula, they closed off all the exits from the place. Then they massacred the celebrating Aztec noblemen. Later famine and smallpox almost wiped out the Aztec civilization, making the conquest of Aztecs complete. The fall of the Aztec Empire resulted in formation of the Spanish overseas empire. It was called New Spain and later came to be called Mexico.
7. Qing dynasty conquest of Ming dynasty, 1616 to 1662, 25 million deaths
The Qing conquest of the Ming, also known as the Manchu conquest of China, was a period of mass bloodshed in China. The Qing dynasty was ruling Manchuria. The Ming dynasty was in the South of China.

6. Conquest of the Americas, 1492 to 1691, 34 million deaths
European colonization of the Americas started from the 10th–11th century onwards. The West Norse sailors explored and briefly settled on the shores of present-day Canada. They were Vikings who had discovered and settled in Greenland and later sailed up the Arctic region of North America alongside Greenland and reached Canada. Extensive European colonization began much later in 1492. It started with Spanish expedition by Christopher Columbus. He sailed west to find a new trade route to the Far East but landed in what was called by Europeans as the “New World”. Hispaniola became the first European settlement in the Americas. Columbus’ first two voyages in 1492 reached the Bahamas and Caribbean islands, Hispaniola, Puerto Rico and Cuba.
In 1497, Englishman from Bristol John Cabot landed on the North American coast. One year later, Columbus’s third voyage reached the South American coast. Thus Spain was the first European power to settle and colonize the largest areas in North America, the Caribbean and to the southern tip of South America. France also founded colonies in the Americas, in eastern North America, Caribbean islands, and small coastal parts of South America. Portugal colonized Brazil. All these conquests and colonization destroyed the indigenous cultures like the Incas and the Aztecs. In North America the Red Indians and other indigenous tribes perished in millions. Eventually, the entire America came under the control of European governments, leading to profound changes to its landscape, population, and plant and animal life.
5. Three Kingdoms War, 184 to 280 A.D., 37 million deaths
The Three Kingdoms was the division of China between the states of Wei, Shu and Wu. All these states claimed legitimate succession from the Han dynasty. It refers to the period between 220 AD and the conquest of the state of Wu by the Jin dynasty in 280A.D. The earlier period, from 184 to 220, was marked by infighting between warlords in various parts of China. The later part of the era was marked by the conquest of Shu by Wei, the usurping of Wei by the Jin dynasty and the conquest of Wu by the Jin. The Three Kingdoms period is one of the bloodiest period in Chinese history.
A nationwide census taken in AD 280 by the Jin dynasty showed a loss of three-fourth of the Chinese population and household. This means roughly three out of four persons perished in the war. Such was the deadly and devastating effect of the war. However, in this period many scientific developments took place due to war efforts. This historical period has been greatly romanticized in the cultures of China, Japan, Korea, and Vietnam. It finds its place in operas, folk stories, novels etc.

2. Mongol Conquests, 1206 to 1324, 40 to 70 million deaths
The Mongol invasions and conquests are part of the history of Asia. These invasions continued for over a century. Genghis Khan, history’s most notorious invader, forged the initial Mongol Empire in Central Asia. He exerted his influence and conquest all around the globe including West Asia, East Asia, Southeast Asia and Europe. The Mongol invasions took place throughout the 13th century. It resulted in a vast Mongol Empire, which extended almost whole of Asia and Eastern Europe. The deaths that occurred during the Mongol invasions were the deadliest in human history. Also, the Mongol invasions spread the deadly bubonic plague. This spread across Asia and Europe and caused death to millions. It was known in history as the Black Death of the 14th century.
The Mongol Empire reached Eastern Europe by the 1240’s. The Mongol empire was an empire of the land, and is called a tellurocracy or continental power, as it spread over continents. It was helped by the grass which supported Mongol cavalry and cattle. The Mongol conquests and plunders took place during the warmer seasons when plenty of grass was available for the horses and the cattle to feed on their way to the conquests. Tartar and Mongol raids against Russian states continued till around 1260. In China the Mongols territories continued into the 14th century under the Yuan dynasty. In Persia it continued till the 15th century under the Timurid Empire. In India, the Mongol state flourished and survived till the 19th century, known as the Mughal Empire.
Thus the Mongols captured almost 20 percent of Earth’s land spreading over Asia and Eastern Europe. The Mongols were the most barbarians and bloodthirsty conquerors. It is said that around 100,000 Chinese committed mass suicide just to avoid being killed by the Mongols.
1. World War II, 1939 to 1945, 40 to 80 million deaths
The Second World War, also known as the World War II or WW2 was the bloodiest war in human history with about 80 million people losing their lives. It was the grand-daddy of all wars ever fought by humans since their existence on earth. It was a global war which began in 1939 and ended in 1945. The majority of the countries in the world were involved in this war. There were two opposite warring camps known as the Axis and the Allies. It was the most widespread war in history that affected people’s lives in more than 30 countries.
The wartime efforts meant that it was a war for existence and the countries sacrificed all their resources in the war. The resources included young men and women as well as the country’s entire economic, industrial, and scientific resources and capabilities. The mass deaths include those caused by the holocaust in which about 11 million people died. It also includes the deaths caused by dropping the nuclear bombs at Hiroshima and Nagasaki. These huge deaths are separate from those in the battle fronts and those caused by aerial bombings. It is the deadliest war that has been seen by humans ever since they evolved as humans in this planet. It is surprising that the humans after all such progress through centuries would indulge in a war that would cause deaths at such colossal levels.
It is so surprising and shocking to find that as humanity is making progress, it is fighting more deadly war against its own species. Before the World War II, all the countries of the world had made tremendous progress. Life for humans had become so comfortable and luxurious after the Industrial Revolution in the nineteenth century. There were automobiles, trains and buses, airplanes, cinema, hotels and restaurants, telephone, radio etc. despite all these luxuries, comfort and entertainment, the greed and animal instincts in man is never dulled and it rears its ugly head. One can only hope that the coming generation understands the horrors of wars, and that these wars can completely wipe off humans from this planet forever.
