2. nearly 60 percent

Nearly 20 percent of the South's men were slaughtered during the war. About 94,000 were killed in action, and more than 160,000 died from diseases.

1. about 9,000
   about 60,000
2. about 400,000

So much for caring for prisoners. Nearly 30,000 men -- on each side -- died as P.O.W.s. In some situations, being captured was as good as a death sentence.

1. scabies
   rabies
2. babies

An epidemic of scabies, caused by particularly awful mites, made life even more miserable by ruining the skin of soldiers' hands and sometimes making daily tasks impossible. Poor hygiene was to blame. It was just one of the many awful aspects of this awful war.

1. about 2%
   about 50%
2. about 32%

More than 620,000 troops died in the war, accounting for the bulk of casualties. That was roughly 2 percent of the entire country's population.

1. about 6 percent
   about 26 percent
2. about 66 percent

Better check on that cough, Jed. Bullets were deadly, but disease was much, much deadlier. About two-thirds, or 66 percent of soldiers, died from disease during the war.

1. true
2. false

It was a horrific war, to be sure, one that ripped apart families and ruined lives. But the American Civil War is far from the deadliest in history.

1. Guatemalan Civil War
   Spanish Civil War
2. Chinese Civil War

The Chinese Civil War was fought for about 15 years (combined) and altogether it killed about eight million people. It may have been one of the deadliest civil wars ever.

1. 1717
   1845
2. 1927

The Chinese Civil War was a modern conflict. It started in 1927, ran until 1937 and took a bit of a breather during World War II. Then the combatants picked up where they left off and fought until 1950.

1. United States
   Japan
2. Cuba

The Chinese laid down their arms against their brothers, only because they had to deal with Japan. In 1937, Japan set out on a course of imperialism by invading its huge neighbor. The Second Sino-Japanese War was the beginning of the Pacific portion of World War II, and it killed millions of Chinese across the land.

The Chinese Civil War was a vicious fight between nationalists and communists. Hostilities never officially ended, and some historians say that this civil war is technically still on.

1. Soviet Union
   Japan
2. United States

The communist government of the Soviet Union was more than happy to offload its surplus weapons (plus those taken from the Japanese in World War II) to the similarly-minded communists in China. The boost in weapons helped them turn the tide of the war.

1. The Bloody Feet
   The Long March
2. The Quick Stroll

In late 1934, the communists were outmanned and outgunned and forced to begin a tortuous retreat called the Long March. Some units may have retreated more than 5,000 miles to escape annihilation by nationalist armies.

1. Mao Zedong
   Chiang Kai-shek
2. Bruce Lee

Mao Zedong was one of the critical communist leaders. After the war ended, he rose to the top of Chinese politics and became one of the most brutal leaders in world history.

1. "ruthless consolidation of power."
   "a well-tended garden."
2. "the barrel of a gun."

Mao said, "Political power grows out of the barrel of a gun." And for the rest of the Chinese Civil War, he encouraged his fellow fighters to kill the nationalists with impunity.

1. true
2. false

The Korean War was definitely categorized as a civil war, especially during the initial outbreak of hostilities. In 1950, the North set the war into motion by invading the South.

1. North
   South
2. neither

America and the United Nations came to the defense of South Korea. China, on the hand, opted to assist the communist North Koreans. The civil war morphed into a proxy war of sorts.

1. more than half a million
   more than 5 million
2. more than 9 million

More than half a million soldiers died during the war. Civilians suffered greater losses, and perhaps 2.5 million of them were caught in the crossfire.

1. true
2. false

Not even close. About 420,000 American troops died during World War II, the biggest war ever. But the American Civil War killed more than 620,000 troops.

1. about 5 percent
   about 15 percent
2. about 30 percent

Perhaps 15 percent (around 1.5 million) of North Korea's population died during the three-year ordeal. Eventually, the two sides hit a stalemate and sent North Korea reeling into its current disheveled state.

1. it was caused by Hitler
   it has the second-highest death toll of all time
2. people were super mean to each other

The Spanish Civil War featured blood-curdling atrocities too gruesome to list here. Suffice it to say, the Spanish found creative and psychopathic ways to butcher each other.

1. Republicans
   Nationalists
2. Democrats

The Spanish Civil War pitted the Republicans versus the Nationalists. The Nationalists were delighted to receive assistance from fascists like Hitler and Mussolini. The war wound up killing more than half a million people.

1. the Blue Army
   the White Army
2. the Purplish Army

The Russian Civil War started in 1917 and found the Red Army fighting the White Army. The Red Army fought for socialism -- the White Army, for a more democratic version of socialism.

1. Joseph Stalin
   Vladimir Lenin
2. John Lennon

Vladimir Lenin was the socialist political firebrand leading the Red Army. Eventually, the socialists won … and established the Soviet Union.

1. 1 million
   9 million
2. 22 million

The Red and White armies decimated each other and killed civilians by the scores. Perhaps 9 million people died in the conflict, which lasted more than half a decade.

1. Japan
   China
2. Korea

The Taiping Civil War was another amazingly destructive Chinese conflict. It started in 1850 and didn't end until nearly 14 years later.

1. Prophet Muhammed
   Jesus Christ
2. Mao Zedong

Hong Xiuquan believed that he was the younger brother of Jesus. The government cracked down on his version of Christianity … and a terrible civil war broke out.

1. true
2. false

The numbers are unfathomable. What started as a government crackdown killed perhaps 100 million people, far more than World War II. Some historians believe that the war killed "only" 30 million, a number that would still make it unbelievably devastating.

1. China
   Egypt
2. Brazil

In the year 755, the An Lushan Rebellion took hold of China. It was a mind-bogglingly deadly rebellion against the rulers of the Tang dynasty.

1. 12 million
   50 million
2. no one knows

The An Lushan Rebellion happened so long ago that no one really knows the death toll. But some researchers believe that tens of millions of people perished in the conflict.

1. population density
   they fight to the death
2. advanced weaponry

For centuries, China's had a relatively high population density compared to other parts of the world. So when civil war breaks out in China -- it's a bloodbath of the worst kind.
