Top 10 Wars in History

The Top Ten
1 World War 2

World War 2 was truly the most powerful war in history. It was also the greatest/most powerful human conflict ever. With 68,000,000-72,000,000 casualties ( more than 2.5% of the world's population at that time), a total of more than 1.2 trillion dollars spent (making it more expensive than all the other wars in history), and even though it lasted only 6 years, 72 countries were involved in the war. It was also the only use of nuclear weapons in warfare, which were two atomic bombs of such incalculable strength/power, damage, and fatalities. No war has ever come nowhere near WW2 deadliness. That explains why it is the most powerful war history has ever seen.

Definitely the worst, you can't ignore the death tolls, especially civilian death tolls, and also the amount of money spent. Just want to clear up a couple things though:

To the commenter that said 50 million Chinese lives were lost, that is very wrong, between 10 and 20 million Chinese dies as in WW2. I'm guessing you're thinking about the Great Leap Forward in which it is believed that up to 60 million Chinese dies as a result of.

Also in regards to the Atomic bomb, it had to be done. Approximately 240,000 Japanese died as a result. If the US invaded Japan and Japan didn't give up (Which they were never going, if they were facing loss they suicide bombed US tanks and even thousands of civilians committed suicide instead of being captured), it was estimated approximately 10 million Japanese would have died and a couple million Americans would have died, as well as it would have consumed time and resources. Also, it allowed the USA to test their new toy, it was a win-win.

The war killed 72 million people and led to the Cold War. Also, it was the most expensive war and the holocaust and many other violent events killed millions of people. The war led to the development of the first atomic bomb and other nuclear weapons and made Hitler more powerful than ever. The war also killed about 2% of the world's population.

More people died and more people were affected by this war than any other in history. You literally had combat occurring in five out of the seven continents and was arguably one of the few wars with a clear good and bad guy side.

2 World War 1

WW1 was a war where countries fought each other with no real bad guy. The war shaped warfare and Europe forever, amazing empires collapsed and ended. Most of the war was fought in trenches with trench warfare. There were bodies everywhere and hundreds dead each day. Constant artillery and gunfire and mud filled the trenches sinking men in like quicksand.

The war killed many people and wounded many more. It was the first war with tanks, flamethrowers, and gas.

Some soldiers would get PTSD or “shell shock” where they would not fight and many were executed. Around 20 million people died. But this war is often overshadowed by WW2 because WW2 had a higher death toll, but that does not mean the WW2 was scarier.

Although it wasn't as dangerous and bloody as the second world war, it was still that of such and did SPARK the second World War.

One of the first of two world wars that reduced and horrified White Europeans and Americans, it broke the back of Imperialist Royal Powers and helped modernize the world. The envy, pain and hatred created by this war shaped the attitudes of "East and West" today. Everything from the television to the assault rifle to the radar and sonar systems were developed to keep power and communication during this war. It was the most shocking and pointless man-made disaster and it raised countries and empires to the ground. - E Chong

Even though WWII caused massive amounts of destruction and had unparalleled influence in the world, WWI was the first war of such scale. It involved the most powerful nations such as the British Empire, Ottoman Empire, Russian Empire, Austro-Hungarian Empire, etc. After that, the world was definitely left wounded, in shock and changed indefinitely with the fall of great empires and the emergence of new powers (United States, Soviet Union, etc).

3 American Revolutionary War

This was the most influential war. We were not losing so badly, the British soldiers fought because it was their job, we fought from passion to win, and when you fight with passion, it helps you win. France and Spain were a big help, but if we didn't fight dirty, we would have lost, we demolished the British at Saratoga. France never switched sides, because they absolutely hated the British, so they wanted to take them down.

Not the deadliest, but chain effects. This got the French in debt and a civil war, which got Napoleon in power, which created the German empire which made ww1, ww2 and Cold War conflicts

It was a war that bore of the greatest country, or, to not be opinionated, one if not the strongest country on earth.

God I love this war. "History started on July 4, 1776, anything before then was an accident." - Ron Swanson

4 American Civil War

The American Civil War is, in my opinion, the most important struggle in American history. How can a nation of free men promote the idea of slavery, and despotism, simply because your a certain race? I understand the American Revolution was the beginning of America, but what makes America so great? Its constitution. God has given rights entitled to every citizen in that country. The constitution was in danger, and the ideas that birthed the nation were in danger. Not only that but it also ended a sort of southern aristocracy in our country. By taking away the way of life that came from only being to farm. It gave the middle class a chance in America. And isn't that what the country is all about? Equal opportunity? That is why the Civil War is the most important war in American History, and should be number 2 on this list. (WW2 is number 1)

Although it wasn't a war on a global scale, the American Civil War affected America on a great scale, with unbelievable casualties at the time, and demolishing slavery as we know it.

I think one of the things interesting about this war is how it's actually kinda hard to tell who the real bad guys and good guys were (if you really look at certain facts and details about both sides).

I also agree with what the previous commenter said, though if the weaponry were more advanced than they were during that time period, then there would have probably been an even higher death rate since that's what caused the high death rates in the first place(using advance weaponry with old battle tactics).

The war also may seem to be one of the only civil wars where the rebels were a part of a formal government (the CSA) instead of just being a part of a militia or paramilitary group.

And bayonets are awesome, laugh out loud.

This is garbage. No way is the American Civil War a larger war than the following wars : Napoleonic Wars, The Russian Revolution and the Mongol Conquests. Just look at the statistics.

American Civil War, Location : US, Death Toll : 1,450,000, Rank on this List : 3
Napoleonic Wars, Location : Europe, Death Toll : 3,700,000, Rank on this List : 7
The Russian Revolution, Location : Russia, Death Toll : 7,000,000, Rank on this List : 8
Mongol Conquests, Location : Asia, Eastern Europe, Middle East, Death Toll : 45,000,000, Rank on this List : 11

5 Vietnam War

I'm not going to get political and say this war was fought for nothing. I'm also not going to say that the US lost, because they didn't, they just... abandoned it. But it did devastate soldiers and citizens, some still affected to this day.

The United States had no right being there. We lost 60,000 men (mostly all college kids) to a senseless war that wasn't going to be won anyway.

Nam was a great war for American History. It showed how America can do whatever we want, whenever we want.

This is the world's most devastating war! There are many most nuclear warheads in history(Wiki). I think it must be 1st.

6 Napoleonic Wars

Being Europe the center of culture and ideas that ruled the globe over the next century, this war made the corner stones of our ideas in modern society. Making the world was we live what it is. It moved every nation in Europe made the system of great powers that we live upon. It made the door for other revolutions like the Germany, Italy, Russia, and China revolution later on. I would think as the most important war of modern era if not for the world wars.

This was why America became so powerful. While Europe was dealing with Napoleon, America was flourishing.

Every country in Europe fighting all over the world with 10,000,000 casualties over a 10 year span.

It brought a new idea of single country unity, as apposed to single states, to Europe.

7 The Russian Revolution

The Russia revolution coursed the cold war the Vietnam, war the Korean war and the Chinese civil war.the cold war coursed conflicts in todays world.

A massive war with a casualty figure close to a world war

Also known as the October Revolution.

All hail lenin

8 Cold War

I can't believe this... how can people be so dumb?
This war was a terrible war, leaving 12 nuclear issuses, sending lots of spys across the globe, causing huge acts of terrorism and leading the battle 1955, the Korean war and the soviet war in Afghanistan. So yeah this war was terrible

Due to the legal procedures of classified issues during the huge long term cold war. We can assume the worst of what has happened behind closed doors. We do know is that the U.S. and the USSR promoted violent actions against each other through geopolitical actions.

Still affects us today. Not as bad as the 2 world wars, but worse than the American Revolutionary War.

It was not a war, it was a period of political tension although it did contain wars. Geez people!

9 Crusades

You mean the wars that lasted from the late 11th century to the 13th century A.D.? All that was was a war between Christians and Muslims. All it accomplished was death. That's all these "holy wars" accomplish. Just death on a grand scale. Nothing holy about it. I don't care WHAT excuse you give me.

Does nobody think about how this "holy war" just led to slaughter, which good Christians and Muslims know is horrible?

I don't know what the heck a type of war is this?

Actually, they were a series of wars.

10 Hundred Years War

Which actually lasted 116 years.

Technically it lasted 116 years (1337-1453).

I lucky not to be there

Cool hundred years

The Contenders
11 Mongol Conquests

I want say about this, maybe this not true, but really this is real world war 1 because war with many country, they conquer a lot of country but fail to conquer Japan. Dynasty Yuan actually never exit, only mongol conquer China 100 years, China history also got fake like Dynasty Yuan, how come China emperor not chinese during Yuan? and kill almost 90% Chinese and don't know we are real chinese or not...don't know because history is write by victory

Eco cleaned the world, saved from overpopulation

They severed peoples heads off, that's messed up

Actually it's the biggest war of all time.

12 Seven Years' War

This war kicked off the economic and political conditions that lead to the French, American, Latin American and other revolutions.

The war that shaped America

13 Syrian Civil War

Civillians don't seem to realize how bad it is! We need to kill the terrorists who support systematically raping children and beheading pregnant mothers

Ongoing for 6 years.

As it is a ongoing war in the Middle East so much have been killed and a lot of people living there refuge to other countries

ISIS vs America vs Rebels vs Syria

14 Gulf War

Short and expensive war

U mean persian gulf war?

15 East Pakistan - West Pakistan War

Bangladesh (East Pakistan) has won the war against Pakistan (West Pakistan) in 1971. West Pakistan launched Operation Searchlight against the people of East Pakistan on the night of 25 March 1971. About 3 million people were killed by West Pakistan. On 16 December 1971, Lt. Gen A. A. K. Niazi, CO of Pakistan Army forces located in East Pakistan signed the Instrument of Surrender. Over 93,000 Pakistani troops surrendered to the Indian forces & Bangladesh Liberation forces, making it the largest surrender since World War II.

It was a time of terror. Small country with little weapons.

India helped bangladesh to get its independence

Bangladesh and pakistan will beat india into 2000 piceses

16 Korean War

It's sad that not much people know of the Korean War. Well, they may have heard of it, but they don't really KNOW about it. Over two and half million people died, and it bore of the wicked dictatorship of North Korea.

Free dim sims after its all over

More than vietnam war

17 Kargil War

Who is that foolish who thinks Pakistan and Bangladesh can cut India into 2000 pieces.(in west-east Pakistan war). I am concern about his mental health, immediate health check up is needed, take him to psychiatrist, he lost his IQ

Pakistan will do that, best joke I've ever heard. The country having Coup every 5 years will defeat The mighty Democratic country. Even when you had the full support of USA than also you never won for ex. The Kargil War, and now the most unstable country will defeat us.

Who ever agrees with that statement(Bangladesh and pakistan will beat india into 2000 piceses) is having mental illness, please show him to a doctor.

(I can understand that it is too hard as there are herdly few doctors in pakistan.)

It is the most important thing of Indian army... It was very difficult but we managed to do it...

Kargil war showcased the impotance of artillery in the modern day battlefield scenario...

Pakistan lost the battle

18 War On Terror

This war seems as if it's never going to end, and the terrorist forces have not only destroyed ancient historical and religious monuments (Taliban), but literally kill innocent, unarmed civilians for no reason... other than for the sake of their religion. Well, I'm specifically referring to the terrorists in the middle east.

I call it Americas pointless war for free oil from the Middle East still very very very vvvery sad though so much dead ;(

19 Turkish War of Independence

After WWI, the Ottoman Empire was forced to be divided and its citizens were to kneel infront of occupying troops. Mustafa Kemal Ataturk went across the whole country to inform people and start the war. Hundreds of thousands of voluntary soldiers went to the frontline, fighting Armenian, Greek, British, French and Italian troops all at once. In the meanwhile, Ataturk opened the grand national assembly and did series of revolutions that made Turkey independent and secular. The Turks won the war, claiming their beloved land.

The first war that showed to the world that imperialist countries could be defeatet, and showed the way how to do it to other leaders like mahatma gandi.

This to be honest

20 French and Indian War

Was a semi world War, took place in British America, Canada, Europe, and India

It was the FIRST truly World war.

21 Thirty Years War

80% dead people yeah yee mmm

22 Bosnian War

The fall of Europe's most powerful country.

23 Second Punic War

The Roman Republic would have never become the Roman Empire and the influence on Western culture to this day would not be influenced by Rome but by Hannibal and Carthage.

This war cost 1/5 of the population of men to be killed. It had a million soldiers going head to head.

If carthage was victorious here, the fate of history would be absolutely different.

It has given us a new understanding of war...

24 Iraq War

This war was fought simply because of a modern day Hitler, Saddam Hussein, so you can expect that there were a lot of casualties.

I think this one of the worst war ever happened. The conflict broke when both sides thinks the other one started and just when people thinks its about to end it starts over again! Ever heard of diplomacy!

I know there was no weapons of mass destruction, but at the time everyone believed there was so the war sadly happened.

Everyone[at least I hope everyone]knows at this point that this war was a money scheme operated by the U. S government,U. S oil companies[such as Halliburton, Exxon Mobil, Deutche Shell, and BP]U. S weapons manufacturers[such as United Technologies, L-3 Communications, Northrop Grumman, General Dynamics, Raytheon, Lockheed Martin, Boeing, and Environmental Chemical]U. S private military corporations[such as Blackwater, Dyncorp, Aegis Defense Contractors, Parsons, and Halo Group]along with Middle Eastern oil Sheikhs[such as Alwaleed Bin Talal, The Bin Laden Family, The Ahmoudi Family, and the Mahfouz family]to plunder the Middle East like viking-pirates. Iraq had something we needed, oil. As a matter of fact 81% of the worlds oil is in the Middle East. We needed a catastrophe to propel us to go to war and when the terrorist hit the trade center it gave us the excuse we needed.
