Top 10 Wars in History

World War 2 was truly the most powerful war in history. It was also the greatest and 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) and a total of more than 1.2 trillion dollars spent (making it more expensive than all the other wars in history), it was incredibly impactful. 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, damage, and fatalities. No war has ever come anywhere near WW2's deadliness. That explains why it is the most powerful war history has ever seen.

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 that WW1 was less significant.

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 you are 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 able 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)

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.

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

Being Europe the center of culture and ideas that ruled the globe over the next century, this war made the cornerstones of our ideas in modern society. It made the world we live in what it is. It moved every nation in Europe and made the system of great powers that we live upon. It opened the door for other revolutions like the German, Italian, Russian, and Chinese revolutions later on. I would think of it as the most important war of the modern era if not for the world wars.

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

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.

This war was just a mistake. The USA did not win this war, like it or not, but this war is still very significant, and it is good to honor the soldiers who fought in it.

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

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

Also known as the October Revolution.

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. What we do know is that the U.S. and the USSR promoted violent actions against each other through geopolitical actions.

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

You mean the wars that lasted from the late 11th century to the 13th century A.D.? All that 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? Good Christians and Muslims know that is horrible.

Actually, they were a series of wars.

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

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