ฝึกพูดภาษาอังกฤษด้วยเทคนิค Shadowing จากวิดีโอ: The Deadliest Wars in History

World War II killed 85 million people.

That's the deadliest war in human history.

Or at least, that's what most people think.

Because if you go back far enough, you're gonna find wars that make World War II look small.

Wars that wiped out entire countries, killed tens of millions of people, and may have even cooled the planet itself.

So let's go find the worst war ever fought, starting in the jungles of Vietnam.

The year is 1965.

The Beatles are everywhere, color TVs are showing up in homes across America, and the US has just landed its first combat troops in a small country called Vietnam.

The war had actually been going on since 1955, but now America was in it.

The crazy thing is, America had the most powerful military on Earth.

North Vietnam had a fraction of the manpower and old Soviet weapons.

This should have been a quick win.

It wasn't.

The war dragged on for 20 years.

So America did what big militaries do when they're losing, they escalated.

The US dropped 8 million tons of bombs on Vietnam.

That's more than every bomb dropped in all of World War II combined.

They also sprayed 18 million gallons of a chemical called Agent Orange over the forests.

The idea was to kill the trees so the enemy had nowhere to hide.

It It also poisoned hundreds of thousands of civilians.

500,000 Vietnamese babies have been born with birth defects from it, and kids are still being born sick today, 50 years after the war ended.

Then there was napalm.

It's a sticky, burning jelly that clings to skin and can't be put out.

The US dropped 388,000 tons of it.

There's a famous photo of a 9-year-old girl named Kim Puk running down a road with her clothes burned off, screaming in pain.

That photo helped turn the world against the war.

But the Vietnamese fighters had their own style.

They lived underground in a 150 mile network of tunnels with kitchens, hospitals, weapons stores, and meeting rooms hidden beneath the jungle.

American soldiers called tunnel rats were sent into these pitch black holes to clear them out.

Most came back up changed forever if they came back at all.

Most of the dead never even picked up a weapon.

In 1968, US soldiers walked into a village called Mai Lai and gunned down more than 500 unarmed villagers in one morning.

Mostly women and children.

About a third of the 3 million Vietnamese killed in the war were civilians like that.

Soldiers on both sides got broken by it.

About 58,000 Americans died in combat.

After they came home, more US veterans died by suicide than were killed in the actual fighting.

The war ended 50 years ago, but 300,000 tons of unexploded American bombs are still buried in the Vietnamese countryside.

They still go up.

They still kill farmers and kids every year.

Three million dead is still small compared to the next one.

Rewind 50 years to a war fought in trenches no wider than a hallway,

where soldiers got torn apart by machine guns and poison gas.

The year 1914.

Empires are still rare, most people have never seen a movie, Europe has been mostly peaceful for a hundred years, and almost nobody alive remembers a major war.

Then a Serbian student shoots an Austrian prince in the head.

Nobody really cared about either of them, but because of a tangle of military alliances, that one bullet pulled every major country in Europe into war.

Within a month, four empires were fighting each other.

Everyone expected it would be over by Christmas.

Four years later, 20 million people were dead.

Here's why World War I was so much worse than anyone expected.

The generals were old.

They were trained back in the 1800s when wars were fought with cavalry charges and brave speeches.

But the technology had changed.

The machine gun could fire 600 bullets a minute.

So when generals sent 10,000 soldiers running across an open field at the enemy, they got mowed down in seconds.

The soldiers stopped charging.

They started digging.

Both sides carved out 25,000 miles of trenches across Europe, enough to wrap around the planet.

And then, they sat in those trenches for four years, getting shell, gassed, drowned in mud, and buried alive.

The trenches were a special kind of hell.

They were full of mud, dead bodies, lice, and rats the size of cats.

When it rained, soldiers drowned in flooded ditches.

When it didn't rain, they got trench foot, which is when your feet literally rot off because they've been wet for too long.

Body lice spread trench fever, which infected over a million soldiers.

Russia had a typhus outbreak that killed 2.5 million civilians on its own.

Men went insane in the trenches.

They gave it a name, Shellshock.

It was PTSD before they had a word for PTSD.

Then there was the gas.

Chlorine gas would burn out your lungs from the inside.

Mustard gas would blister your skin and blind you.

Soldiers described seeing a green cloud roll toward them and knowing they had 20 seconds to find their mask or die.

And for what?

Some battles were fought over a few hundred yards of mud.

The Battle of the Somme stretched on for five months and killed a million men.

By the end of it, the British had advanced six miles.

Verdun was somehow worse.

300,000 dead over 10 months, all fighting over the same patch of dirt.

But the real horror of World War I was what came after.

The Spanish flu spread through the trenches and killed another 50 million people around the world.

Russia collapsed into a communist revolution, Germany got buried under impossible debt and starvation,

and the peace treaty was so unfair that another war was almost guaranteed.

The world would get it 20 years later.

and it would be much, much worse.

Go back another 700 years, long before machine guns and gunpowder.

The deadliest weapon on earth was a horse and a man with a bow, and one man used both to kill 40 million people.

When the Mongols took the city of Urgench in 1221, they handed each of their 20,000 soldiers a quota.

24 prisoners to personally execute by hand.

Do the math.

That's almost half a million people killed one at a time in a few days, and Urgench wasn't even one of their famous massacres.

By the way, we made a full video on the Mongol Empire.

If this is your thing, go check that one out after this video.

I'll link it in the description.

The Mongols ran a simple system.

Open your gates and live.

Close your gates, and they would kill every person inside, including the babies and the pets, then stack the skulls into pyramids outside the walls.

This was the Mongol Empire's marketing strategy.

And it worked because they could actually back it up.

100

Genghis Khan was born around 1162 in Mongolia.

101

His father got poisoned when he was nine, the tribe abandoned the family in the wilderness to starve.

102

As a teenager he was kidnapped and enslaved, but he escaped.

103

By his 40s he had united every nomadic tribe in Mongolia under his rule.

104

Then he turned his eyes to the rest of the world.

105

Mongols had a few advantages nobody else had.

106

They lived on horseback from the age of three and could shoot a bow accurately while riding at a full galley.

107

Their composite bows fired arrows 300 yards, twice the range of most European bows.

108

They were also nomadic, so they didn't need supply lines.

109

They just brought everything with them, including portable forges to fix weapons on the move.

110

But the real weapon was psychological.

111

The Mongols would send messengers ahead to a city with the same message every time.

112

Open your gates and live.

113

Close your gates and we'll erase you.

114

Some cities ignored the message and learned the hard way.

115

In 1221, the Mongols sacked the city of Merv and ordered every survivor to be killed.

116

Soldiers were each assigned 300 to 400 prisoners to execute personally.

117

The Chronicles say the killing took 13 days.

118

Around 700,000 people died in that one city.

119

Then, the Mongols left, came back a few days later, and killed the survivors who had been hiding under the bombs.

120

This was the standard playbook.

121

Persia's population dropped from 2.5 million to 250,000.

122

That's 90% of the country just gone.

123

In 1258, they sacked Baghdad, the most advanced city in the world at the time, full of libraries and universities.

124

They threw so many books into the Tigris River that the water ran black with ink for weeks.

125

The killing in Baghdad alone hit somewhere between 200,000 and a million people.

126

Across the empire, the Mongols killed around 40 million people.

127

That was about 10% of every human alive at the time.

128

The destruction was so massive that scientists today can actually see it in the climate data.

129

So many farms got abandoned

130

that forests grew back across millions of acres pulling enough CO2 out of the atmosphere to slightly cool the planet.

131

The Mongols also might have started the Black Death.

132

In 1346, they were attacking a trading city on the Black Sea called Kappa.

133

Plague broke out in their camp, so they catapulted the infected corpses over the city walls.

134

Italian traders and Kappa caught the disease, sailed home, and accidentally launched a pandemic that killed a third of Europe.

135

The Mongols took 150 years and half the planet to kill 40 million people.

136

Now jump forward 400 years to Europe where one country lost an even bigger share of its population in just 30 years.

137

All over two slightly different versions of the same religion.

138

In May of 1618 a group of Protestant nobles in Prague got upset with their Catholic king.

139

So they marched into the royal castle, grabbed three of the king's officials, and threw them out of a third floor window.

140

Somehow the officials survived the 70-foot fall.

141

The Catholics said angels had caught them.

142

The Protestants said they landed on a pile of manure.

143

Either way, that one stupid moment kicked off a 30-year war that killed 8 million people.

144

This was the 30 Years War, and it might just be the most pointless mass slaughter in history.

145

It started as a fight between Catholic and Protestant Christians in what is now Germany.

146

Both sides thought God was on their team.

147

Both sides were willing to burn the other side alive to prove it.

148

Pretty soon, every major power in Europe jumped in to grab land while their neighbors were busy fighting.

149

Sweden invaded, Spain invaded, France invaded, Denmark invaded.

150

The war stopped being about religion and became about everyone trying to take a slice of Germany while it was bleeding out.

151

Back then, countries didn't really have professional armies.

152

They hired mercenaries.

153

They were basically armed gangs who fought for whoever paid them.

154

The problem was, nobody could afford to keep paying them for 30 years.

155

So the mercenaries fed themselves the old-fashioned way.

156

They robbed and burned their way through whatever village they were stationed in.

157

Whatever they couldn't carry, they ate.

158

A normal week for a German peasant might look like this.

159

Monday, Catholic mercenaries take all your food.

160

Wednesday, Protestant mercenaries burn your barn down for hiding food.

161

Friday, a third group of mercenaries shows up just to be safe.

162

Saturday, you're either eating tree bark or you're dead.

163

By 1630, entire regions of Germany had been raided so many times that there was nothing left to take.

164

So, the famine started.

165

Then the plague started, because diseased mercenary armies don't really wash their hands.

166

Combat itself only killed about 3% of civilian deaths.

167

The other 97% died from disease, starvation, and dysentery brought by the soldiers.

168

Wolves wandered into empty villages because there were no humans left.

169

Starving peasants resorted to cannibalism, digging up bodies from cemeteries for food.

170

By the time it ended in 1648, Germany had lost up to 40% of its entire population.

171

Some regions lost two-thirds.

172

Cities like Magdeburg, which had been one of the biggest in Germany, got burned to ash.

173

Only a few hundred people survived out of 25,000.

174

The country wouldn't fully recover for over 100 years.

175

The craziest part is that nothing was really decided.

176

The peace treaty basically said, let's all go home and agree to disagree about religion.

177

After 8 million deaths and three decades of suffering, the official answer was, fine, you do your thing, we'll do ours.

178

But the war that killed the biggest share of humanity in all of history happened centuries before this one, in China.

179

And almost nobody in the West has ever heard of it.

180

His name was Hong Xiuquan.

181

In the 1840s, he was a Chinese guy trying to pass the Imperial Civil Service exam.

182

This was the test he had to take to get any government job in China.

183

It was famously difficult, with a pass rate of about 1%.

184

Hong took it four times.

185

He failed four times.

186

After the fourth failure, Hong had a complete mental breakdown.

187

He locked himself in his room for 40 days and started seeing visions.

188

In one vision, an old man with a long beard appeared to him

189

and told him he was actually God's second son and Jesus' younger brother.

190

When Hong recovered, he believed it completely.

191

And he wanted to bring God's kingdom to earth, starting with overthrowing the Chinese government.

192

By 1850, Hong had built up a private army of around 30,000 farmers

193

and miners who had also concluded that God's brother had finally come to save them.

194

They called themselves the God Worshippers.

195

They marched across southern China, swelling to over a million followers, and they were genuinely good at fighting.

196

Hong also recruited 10,000 women into their own all-female battalions.

197

They marched barefoot in trousers and fought right next to the men.

198

For 19th century China, that was unheard of.

199

In 1853, they captured Nanjing, which was one of the biggest cities in the world of the time.

200

Hong renamed it the Heavenly Capital and declared the Taiping Heavenly Kingdom.

201

The rules were stripped.

202

No opium, no alcohol, no tobacco, no gambling, no prostitution, no foot binding.

203

Men and women had to live in separate camps, even if they were married.

204

Sex was banned.

205

Except of course for Hong himself.

206

He had a palace with 88 concubines and rarely came out.

207

The rules were for everyone else.

208

Meanwhile, the actual war was devouring China.

209

The Qing Dynasty was already weak from losing the Opium Wars with Griffin.

210

Now they had a Christian death cult holding half their country.

211

They had to hire Western mercenaries to help fight.

212

One British officer, literally named Chinese Gordon, led a force called the Ever-Victorious Army against the Taiping rebels.

213

The fighting was savage, but the famine was worse.

214

Both armies took food wherever they went, crops failed and villages emptied out, people ate tree bark and boiled leather, and eventually they ate the dead.

215

Some entire provinces had population drops of 70%.

216

Travelers described walking for days through southern China without seeing a single living person.

217

In 1864, after 14 years of war, Qing forces finally took back Nanjing.

218

Hong had died a few months earlier, possibly by suicide, possibly by eating poisonous weeds in his palace garden because he refused to eat normal food.

219

When the Qing soldiers broke through the walls, they killed over a hundred thousand people in the city in a single week.

220

Then they dug up Hong's body, beheaded it, and blasted his ashes out of a cannon so he he would have no resting place anywhere on earth.

221

By the time it was over, somewhere between 20 and 30 million people were dead, mostly civilians.

222

Some estimates go as high as 70 million.

223

Either way, that's more than every American killed in every war the country has ever fought, combined, multiplied by 20.

224

But the most brutal war ever fought was only 80 years away.

225

It happened in living memory.

226

Some of the people who fought in it are still alive today.

227

World War II killed between 70 and 85 million people.

228

That's more than the entire population of the United Kingdom today.

229

Wiped out in six years.

230

And it gets worse from there.

231

It started in 1939.

232

Germany was a wreck after World War I.

233

The economy was gone and the population was starving.

234

A failed art school applicant named Adolf Hitler had taken power, promising to fix everything.

235

He fixed it by invading Poland and starting the biggest war in history.

236

But Germany was only one part of it.

237

On the other side of the world, Japan had been at war for years already.

238

They had invaded China in 1937, and they were doing things there that made the Mongols look professional.

239

The Japanese army committed a six-week massacre in the city of Nanjing, killing somewhere between 200,000 and 300,000 civilians.

240

Soldiers held sword-killing contests with each other to see who could behead more prisons.

241

Then there was Unit 731, a Japanese army facility where scientists ran experiments on living people.

242

They infected prisoners with plague.

243

They dissected them without anesthesia to see how their organs fit.

244

of the victims were children.

245

In Europe, Germany was building something even more systematic.

246

The Nazis decided that certain groups of people, mainly Jews but also Roma,

247

disabled people, gay people, and political prisoners should be eliminated entirely.

248

So they built factories whose only job was killing people.

249

Auschwitz alone murdered over a million human beings.

250

The total death toll in what we now call the Holocaust was around 11 million.

251

6 million of them were gibberish.

252

While the genocide was happening, the actual military war was vaporizing entire countries.

253

The Eastern Front, where Germany invaded the Soviet Union, was the largest and bloodiest theater of war in human history.

254

About 30 million people died on that single front.

255

And soldiers at the front line had a life expectancy of 24 hours.

256

The Battle of Stalingrad alone killed close to 2 million people.

257

The Siege of Leningrad lasted 872 days, with the city completely sealed off and starving.

258

People ate wallpaper paste and boiled leather belts to make soup.

259

Around 800,000 civilians died in that one city, most of them from starvation.

260

The cities themselves were being erased sides started bombing each other's civilians on purpose, hoping to break morale.

261

London got blitzed, Berlin got flattened, the British and Americans firebombed the German city of Dresden, killing 25,000 people in two nights.

262

Tokyo was the worst of all.

263

On March 9th, 1945, American bombers dropped jelly bombs on the wooden steel.

264

The fire created its own weather, and 100,000 people died in just a few hours.

265

It was one night.

266

There were dozens more raids like it.

267

Then came the atomic bombs.

268

Hiroshima got hit on August 6th, 1945.

269

Nagasaki, three days later.

270

About 200,000 people died, half of them in the first few seconds.

271

Survivors described seeing the shadows of vaporized people burn permanently into the walls.

272

By the time it all ended in September 1945, almost 80 million people were dead.

273

50 million of them were civilians.

274

The Soviet Union alone lost 27 million people, 14% of its entire population.

275

China lost 20 million more on top of it.

276

Most of Europe and East Asia was in ruins.

277

There were 17 million displaced people wandering across continents with no home run.

278

That's why World War II is the most brutal war in human history.

279

The death toll alone is bigger than any war before or since.

280

And on top of that, World War II combined every kind of horror humans had ever invented, including death camps, atomic bombs,

281

mass starvation, biological experiments, and the firebombing of civilian cities, into one war on six continents.

282

And it ended with humanity inventing weapons that could end the world.

283

That's why no major power has dared to start one like it in 80 years.

284

Because everyone alive today knows exactly what would happen if we did.

285

But there is one war that may have wiped out an even larger share of humanity.

286

This war is called the An Lushan Rebellion.

287

It may have killed one out of every six people alive on Earth at the time.

288

And it started over a fat guy and a love triangle.

289

To understand it, you have to know where China was at this point.

290

In the year 755, China was the richest, most advanced country on earth.

291

The Tang Dynasty was running a peaceful empire of around 50 million people.

292

They had paper money, gunpowder, printed books, and skyscraper-sized pagodas.

293

Europe was still mostly mud huts and plague.

294

The Tang Emperor was a guy named Zhuangzong, and he was deeply in love with a younger concubine named Yang Guifeng.

295

Like, obsessed level in love.

296

He let her family run the government and stopped paying attention to ruling the empire.

297

He just wanted to hang out with Yang.

298

Yang had a favorite too, a general named An Lushan.

299

An Lushan was 350 pounds and half Turkish.

300

He was also known for being a hilarious entertainer.

301

He would dance for the emperor by jumping up and down even though he was massive.

302

The emperor thought he was the funniest man alive.

303

Yang adopted An Lushan as her son, even though he was 30 years older than her.

304

This is the part where everyone in the imperial court started asking questions.

305

Tensions built between Ahn Lushan and Yang's cousin, who was the prime minister.

306

Eventually, Ahn Lushan got tired of court politics,

307

so in 755, he gathered 150,000 troops from the northern border and marched on the capital.

308

The Tang army was caught completely off guard.

309

Ahn Lushan captured the city of Luoyang within months and declared himself Emperor of a new dynasty.

310

The Emperor and Yang Guifei tried to flee, but on the road, the Emperor's own soldiers mutained.

311

They demanded that Yang be executed because they blamed her for the entire mess.

312

The Emperor was forced to watch his favorite person get strangled in front of him.

313

He abdicated soon after, broken.

314

But the war kept going long after the capital fell.

315

It lasted eight years.

316

An Lushan went blind from diabetes and was murdered by his own son in 757.

317

The son was then murdered by a general, who was himself killed shortly after.

318

The fighting just kept going.

319

Both sides hired foreign mercenaries, mostly Uyghur horsemen who looted Chinese cities as payment.

320

By the time the rebellion was crushed in 763, the death toll was huge.

321

The official Chinese census went from 53 million people to 17 million people.

322

36 million missing.

323

Some of that was probably tax records breaking down.

324

Even the conservative estimates put the death toll at 13 million.

325

The higher estimates put it at around 36 million, which would mean the An Lushan Rebellion killed a bigger share of humanity than any other war before or since.

326

The Tang Dynasty technically survived, but it never really recovered.

327

The empire spent the next 150 years slowly falling apart from the inside.

328

And hey, don't forget about that Mongol Empire video.

329

We worked our asses off on that one.

330

Trust me, you want to watch it.
