World’s Top Ten Biggest Wars in History

Ever since the evolution of man-kind, there has always existed this peculiar rage & urgency in our race to prove one’s dominancy upon the other. We all know that in ancient gladiator times power was determined by the size of the army and their ability to win wars, well has it changed that much? We humans seem to be caught in a never-ending war between ourselves whereas the beneficiaries never have done or will do any of the dirty work and just control everything from behind the scenes. The Oxford dictionary describes the act of war as a, ‘’ state of armed conflict between different countries or different groups within a country.’’

The following list is not in a chronological order, instead is sorted from the war with the lowest death toll to the highest. So here, we have the world’s ten biggest bloodiest wars in history.

 10. American Civil War (1861-1865)


The American Civil War was basically a war fought between the ‘North’ or the ‘Union’ and the South also known as the ‘Confederacy’ formed by the secession of several southern slave states. It was also known as the War Between the States or simply just the Civil War. The war had its roots set on issues of slavery and the extensions of it into the western territories of America. More than 800,000 people were killed in the war.


 9. Soviet War in Afghanistan (1979-1989)


A decade long war between the Soviet-led Afghan forces and the multi-national insurgent groups called the Mujahedeen; with the death toll of well over a million Afghan civilians and those that were participants in the war. The war although fought only in Afghanistan, billions of dollars were funded by countries like the United States, United Kingdom, Saudi Arabia and a few other.


8. Vietnam War (1955-1975)

Also known as the Second-Indochina War and as this period of American involvement in Vietnam made it the American War was basically a sequel to the First Indochina War that was fought between North Vietnam – supported by China and other communist allies and South Vietnam – supported by the United States and other anti-communist allies. Over a million civilians were killed in addition to the hundreds of thousands participants in the war.


7.  Thirty Year’s War (1618-1648)

Thirty Year’s War

One of the bloodiest wars on religion, as the name suggests itself a war that lasted over three decades; Thirty Year’s War was one of the longest and the most destructive conflicts in the European history and one of the longest continuous wars in Modern history. Historians have still not come to terms on the fact as to what ignited the fighting; rather there seem to be many parallel causes that fueled the war overtime. It grew as a religious war at first, but then developed into a continuation of the Bourbon-Habsburg rivalry for the European political pre-eminence with the death toll of well above 5 million people.


6. Napoleonic Wars (1803-1815)

napoleonic wars

Napoleonic Wars were a series of wars declared against the Napoleon’s French Empire by the opposing coalitions. The war was initially sparked by the French Revolution of 1789 and played out on an unprecedented scale, mainly owing to the application of modern mass conscription. French power was stronger than ever as Napoleon armies had conquered much of Europe but came to an ultimate military defeat after France’s disastrous invasion of Russia in 1812. With over six and a half million people dead the war came to an end resulting in the restoration of the Bourbon-Monarchy in France and the creation of the Concert of Europe.

5. Russian Civil War (1917-1922)

A war fought between the Bolshevik Red Army and the White Army, the loosely allied anti-Bolshevik forces; in the former Russian Empire was in fact a multi-party war with notably many foreign armies like the Allied Forces and pro-German armies warring against the Red Army. The war lasted only five short years but resulted in the death of over 7 million people all in all.

4.  Conquests by the Empire of Japan (1894-1945)

Conquests by the Empire of Japan

The Empire of Japan literally means the empire and world power that had existed from the Meiji Restoration that happened on 3rd January 1868 to the enactment of the post World War II Constitution of Japan on 3rd May 1947. Only after suffering a couple defeats and the atomic bombings of Hiroshima and Nagasaki did the Empire of Japan surrendered to the Allies on the 2nd of September, 1945. The American involvement gave birth to a new constitution and was forced on from 3rd May, 1947 officially dissolving the Empire which had already been the cause of over 20 million deaths.

3. World War I (1914-1918)

World war 1

World War I was one of the bloodiest global wars in the history of man-kind centered in Europe that began on 28 July 1914. It was previously called the Great War from its occurrence until the start of the mother of all blood baths in history, World War II. It involved all the great powers in the world, assembled in two opposing alliances the Allies and the Central Powers. The death toll for World War I was estimated to be around a staggering 50 million plus.

2.  Mongol Conquests (1206-1368)


A war that sparked in the dawn of the 13th century which resulted in the vast expansion of the Mongol Empire that covered much of Asia and Eastern Europe by mid 1300. It is believed by many historians that Mongol raids and invasions were one of the deadliest conflicts in human history up through that period. The Mongols brought terror to Europe on a scale not ever seen again until the twentieth century with more than 60 million killings on their way.

 1.  World War II (1939-1945)

world war 2

Also known as the Second World War, fought between the vast majority of the world’s nations – including all the great powers – eventually forming two opposing military alliances like the First World War; the Allies and the Axis. Marked by mass deaths of civilians, including the Holocaust and the only use of nuclear weapons in warfare up to present, the war resulted in over 70 million fatalities and is believed to be the deadliest, bloodiest war ever in history which shook forever the foundations of our own existence.

Final Conclusion: Although these wars were fought on different territories by various groups and countries on different time periods in history; the ones who always suffered and lost were the same innocent civilians. Never in the field of human conflict was so much owed by so many to so few, like in these pointless wars for blinding power. Albert Einstein was once asked by a reporter after the World War II had ended, ‘’Sir what type of machinery and weapons do you think will be used in the World War III?’’ He answered with a smile, ‘’I don’t know about the World War III but if there is a World War IV, then it will surely be fought with sticks and stones.’’

  1. Bullshit. American civil war in top 10? hahahaha. You are probably a patriotic Merican. Let me tell you something. USA hasnt ever fought a big war that centered around usa. It only helped the big boys now and then. The vietnam war and soviet war in afghanistan dont belong in a list like this neither

    • Are you just jealous that your country does not have a major war that is no the list?

      And yes they do, you historically ignorant tard.

      • Americans came in WW II only to avoid soviets to conquer whole Europe. They came for their own benefits, as they always do.

        Maybe you should ask yourself why they maintained Hiro Hito on his throne while killing thousands of innocents in Hiroshima and Nagasaki.

        Ask yourself also with they trained and supported moudjahidins in Afghanistan before calling them talibans and fighting them.

        Ask yourself where are the mass destruction weapons proofs of Bush for invading Iraq.

        Ask yourself why IBM (and especially the Hollerith machine) were sold to nazis to help organize holocaust….

        I like to see stupid american patriots like you with only a good or bad in a story.

        And remember that USA wouldn’t either exist if frenchies didn’t come to support them in Indepedance war.

        • America came into the WWII because of Pearl Harbor not because of the Soviets.
          Honestly America’s priorities were not that focused on them just yet.
          Hirohito was spared because there existed no strong evidence of him even being in control of his country and since he only spoke to the nation when surrendering.
          Bush is generally considered a moron who shouldn’t have been put in power in the first place.
          IBM is a company not America. Yes it is American however it is not America.
          France helped America in its because it wanted to hurt it’s current rival England. Most countries need help getting on their feet in order to do anything worth while. Not to mention that countries must be recognized by other countries to even be considered countries. And it doesn’t really matter where we were then.
          Now… I hope you also notice that the original comment made a comment about the U.S. not being in any U.S. centered wars. NOT the validity of U.S. actions.
          Thank you.
          A not so proud American.

          • Technically if we go to another country, there are countries considered “more free.” But when I was talking about U.S. and being a “Not so proud American” I was not talking about me resenting the rights and liberties I do have. I am simply stating that I am not proud of my country and what it does all the time and therefore attacking the idea that I say it because I am a patriot so that it will not be used against me. Sorry for offending you. I mean no disrespect. Thank You.

          • It is possible to be a proud American and not agree with certain actions of our government.
            I love this country.

        • Yeah, and the attack on Pearl Harbor had no effect. Soviet originally supported the Nazis because they believe they could have a share of Poland if Hitler could be trusted. In the end, they were fooled.
          Hirohito was not as foolhardy as Hitler to die-hard till the end. His speech about nuclear weapon was true to an extent. Besides, he was the Emperor of Japan, and it could not be without the permission of his people that he be tried as a war-criminal, unless the US had terrorized the Japanese so that they would give in. US occupation of Japan is widely considered more humane than, say, Soviet occupation of Poland and Germany.
          And SHUT THE HELL UP ABOUT THE HOLOCAUST! The Jews extermination had many roots, some of which are controversial, some of which are not even bothered and some of which are just made up by corporations to accuse one another. For example, the RAF claimed that Hitler killed the Jews because he would get money out of that. PURE BULLSHIT! The fact that everybody is speaking about it without solid proofs just makes me sick.
          I am from Vietnam. And I find your comment offensive to the site.

      • I agree in some points, but the United States would never fund the Holocaust, and of course bush attacked Iraq because of nuclear weapons, the Islamic people have proved time and time again that they have no buisness with nuclear weaponry. and what gives you the right to judge the U.S? had it not been for the United States, Hitler would have conquered Europe, and the Japanese asia, and had you properly studied American history, you would know that the Continental Army had already won the war before the “frenchies” (again very prejudice) came to help. General Lafayette may have trained our militia, but not the Army. all the french did to help in the effort was blockade Cornwallis from escaping, due to the fact that the Continental Army had already wor the war

        • It is just my belief, but the since the Nazis invested a lot in the Holocaust, it is possible that is was funded indirectly by several countries. Perhaps through borrowings or leasing. Hitler planned the Holocaust long before world war 2. How else would they be able to build up such massive war-machine when their economy was in turmoil from the Great Depression? I might be wrong though, as Germany was an autarky state (without international trade).

      • You’re proud of a country that is responsible for terror as america supported mujahideen and pakistan ,america starts every war in world so dont give this bullshit no one likes to be in this list except people like u and country likeamerica

        • And what country would you be proud of belonging to? One that breeds terrorists, or perhaps one that persecutes people because they have different beliefs? And oh my gosh, maybe one that thinks it is ok to rape and torture women because they are not equal with men???

      • the only super power left what did you write that from your computer made in japan or china saying america is the only super power left is really ignorant don’t get me wrong i love america but you are being stupid Europe asked america to take part in the world wars because England was smart enough to realize that if if the germans took England america was screwed and don’t say that you would have won anyway because you would have been fighting a war on 2 sides japan and Germany would have been bombing and attacking you.are you really saying that Europe can’t fight their own wars because america did that so well in the middle east i don’t even really care but your being stupid

  2. i just had a look at all the conversation!nice discussions but tell me ! Is there any need to become so personal when it comes to countries,freedom and rights.It is really very good to get knowledge about history and i personally appreciate Mr Nikhil to upload such information here.You know what ! i am from India and i feel good that i am Indian but i really cant say that i proud to be an Indian because every country has some good and bad.Ever day i see so many wrong things around me and it happens every where in the world ,so we should have a healthy discussions on the present situations in the countries ..

  3. Since 1206(mongol conquests), up until 1945(world war II), 220 million people have died from these wars, and this is not including the other smaller wars that have occurred in between. So imagine if there were no wars ever, all of these people would have been alive, and procreating. Making Babies!!!! Multiplying since 1206!!! The planet is over crowded as it is. If not war then it would have been disease, or starvation. Disease and starvation lead to desperation. Desperation destroys societies. People fight wars because of their beliefs. And beliefs that are willing to die for will bind a society by a common chord. Does that make any sense? Wars keep the people focused. Remember the pride that America gleaned from when the woman went into the factorys to build war machines for their husbands? remember the good feelings from those posters?people got together for a cause, they werre focused on a common goal. just my opinon. not facts.

  4. This is a rubbish list. It ignores all of the conflicts in Ancient China and the 19th Century Civil War that had a larger death toll then the American Civil War.

  5. War is evil regardless who started it and who ended it. No credit of any kind from this end. You kill people which I reject from every part of my body–from soul. Every human being is part of me from the beginning of human existence–from civilization if there is thing like that. Human hearts are warped–dirty and very sick. I continue to search where we fit into peace and understanding that we must be about-Human being. We human beings work at it to find where we fit in. There is competition between evil and good-who wins I wonder. The good must prevail. I’m still on that journey with sadness working at where I fit in. Loving my neighbor that Jesus Christ our LOrd died for. Pray for me if you pray. I pray seriously..
