"Religion has been the cause of the most wars." Have you ever heard this line?
George Carlin once said to rapturous applause, “More people have been killed in the name of God than for any other reason.” Is he right?
This is one of history's greatest misconceptions. Nevertheless, it's held as an historical fact - even Gospel!
"When I hear someone state that religion has caused most wars," Rabbi Alan Lurie said in a Huffington Post article, "I will often and ask the person to name these wars. The response is typically, 'Come on! The Crusades, The Inquisition, Northern Ireland, the Middle East, 9/11. Need I name more?'"
How would you respond to this? That's a lot of wars, come to think of it. Right? Not really. That's just where the magician wants us to look.
What about the Crusades, the Inquisition, etc.?
An objective look at history shows a very different picture. Wars in the name of religion have been only a tiny fraction of the history of warfare.
Charles Phillips and Alan Axelrod in their 3-volume Encyclopedia of Wars identify 1,763 separate wars as forming the entire history of recorded warfare.[1] Of these, only 123 were classified has having a religious cause. That's not much at all.
That's only 7% of all wars in recorded history! 7% isn't even close to a majority. In fact, you know what that's called? A minority.
Aren't the Wars of Religion the bloodiest of all wars?
That 7% of wars represents the bloodiest of all wars, right? The ones with the highest body counts, right? Let's see ...
Here are the bloodiest wars in history:
- World War II (1939-1945) - 70-118 million people died
- Mongol Conquests (13th century) - 60-70 million, according to legend around one million Chinese people committed mass suicide just to avoid the Mongolian conquest
- World War I (1914-1918) - 40 million
- Three Kingdoms (184-280 AD) - 30-40 million, the division of China into the Kingdoms of Wei, Shu, and Wu, following the end of the Han dynasty and the Yellow Turban Rebellion, a Taoist uprising
- The Manchu Conquest of China (17th century) - 25 million
None of these were religious wars.
What do you think was the bloodiest "religious" war in history? The Crusades, right?
No. The first one on the list that could be construed as "religious" was the Taiping Rebellion.
An estimated 20-30 million died in this Chinese uprising. The uprising was led by Hong Xiuquan, who called himself the Son of God and the brother of Jesus. Hong sought to convert the Chinese people to his religious movement, The God Worshiping Society. Ultimately, the goal of the Taipings was the overthrow of the Manchu dynasty.
It is difficult to classify the Taiping Rebellion as a religious conflict, much less a Christian one. Hong's appeal was not his Christian message, but his economic one. He advocated an early version of communism, which, as we know, would eventually take root in China.
According to this list of the top 100 wars and armed conflicts with highest estimated death tolls, the Crusades rank at No. 24.
Also, remember, the Crusades were a defensive maneuver against the ongoing Muslim conquest of Europe:
The Reconquista was, more of less, the precipitating event which led to the ...

So in the history of warfare, what percent of people who died in religious conflicts?
Less than 2 percent of all people killed in warfare. While, for example, it is estimated that approximately one to three million people were tragically killed in the Crusades, and perhaps 3,000 in the Inquisition, nearly 35 million soldiers and civilians died in the senseless, and secular, slaughter of World War 1 alone.Where do the Crusades rank among the deadliest wars in history?
Top ten, right? Nope.According to this list of the top 100 wars and armed conflicts with highest estimated death tolls, the Crusades rank at No. 24.
Also, remember, the Crusades were a defensive maneuver against the ongoing Muslim conquest of Europe:
Bloodiest Christian conflict in history?
The Reconquista. This was the nearly 800-year period of Spanish history following the Muslim conquest of Spain and Portugal, the Iberian Peninsula. Like the Crusades above, this was a defensive effort. I have included the video above to describe this period in detail.The Reconquista was, more of less, the precipitating event which led to the ...
The Spanish Inquisition killed millions, right?
How bloody was the Inquisition?
There are some wild claims about the Inquisition floating around. One such claim is that 95 million people died during the Inquisition. If this were true, virtually the entire population of Europe would have been wiped out. The Black Plague killed only 25 million, for example.
In fact, it is estimated that only 6,000-8,000 people were executed during the 350 years of the Inquisition. Not the Spanish Inquisition alone, but the entire Inquisition throughout all of Europe.
Many of the thousands of executions conventionally attributed to the Church were in fact carried out by non-church tribunals.
Henry Kamen, a fellow of the Royal Historical Society and professor at the University of Wisconsin Madison, wrote the following: [3]
Taking into account all the tribunals of Spain up to about 1530, it is unlikely that more than two thousand people were executed for heresy by the Inquisition. [...]
It is clear that for most of its existence that Inquisition was far from being a juggernaut of death either in intention or in capability. [...] It would seem that during the 16th and 17th centuries fewer than three people a year were executed in the whole of the Spanish monarchy from Sicily to Peru, certainly a lower rate than in any provincial court of justice in Spain or anywhere else in Europe.
No matter the death toll, the Inquisition is still a black mark on the Church
Don't get me wrong, this was not a proud moment in the history of the Church. It's a black mark, for sure. Pope John Paul II publicly apologized the Inquisition in 2000.
Summary: Is Religion the cause of the most wars?
No, absolutely not. Religion has been the cause of 7% of all wars, accounting for 2% of the deaths caused by war. The same cannot be said of atheist communist or nationalist governments in just the last century.Even so, the Crusades and the Reconquista were both the result of Muslim aggression.
Can it be said that Christianity is a Religion of Peace?
Absolutely. Islam, not so much. This begs the question, then. Is it even fair to lump Christianity in with Islam when accounting for the bloodiest wars in history?
There is one glaring omission in all this discussion of warfare: Jihad.
Nevertheless, here are some more sources on the topic of Jihad, including Robert Spencer's and Raymond Ibrahim's new books on the subject:

Total Death Toll of Muslim Jihad
Professor Bill Warner, author of several books on Islam, estimates the total number killed in Muslim jihad to be 270 million. Warner is a somewhat controversial figure, however. In today's political climate, it is difficult to find sources providing the historical death toll of Islamic Jihad. Post 9/11, we find many forcing a narrative of Islam being essentially peaceful in nature.Nevertheless, here are some more sources on the topic of Jihad, including Robert Spencer's and Raymond Ibrahim's new books on the subject:

Guess what ? The encyclopedia that theists cite , lists OVER 25% OF WARS AS BEING RELIGIOUS.
For the 7% claim to be true you would need to exclude (inter alia), Arab Israeli Wars, Sultanate Wars, Holy Roman Empire Wars, Jewish Revolts , Muslim Wars and Sikh Wars – names given by the authors of the encyclopedia. Guess what ?
1) These wars are not mentioned in the index under "Religious Wars" - how convenient for theists !!
2) The authors make it emphatically clear in the body that they are religious wars.
You cant make a list of religious wars that only has 7% of them - ignoring 19% - then claim that there are only 7% !!
https://community.fandom.com/wiki/User:Glottalpoly
2) You claim that Only about 7% of all wars in history have been waged for religious causes - but your source is A&P Axelrod & Phillips. However A&P MAKE NO SUCH CLAIM ! Anyone who has read the introduction to A&P which REPEATEDLY EMPHAISES THE RELIGIOUS CAUSES OF WARS would immediately wonder how that can be reconciled with the 7% claim.
How is it “reconciled” ? You rely on a heading in the index “Religious Wars”. Correct - the wars under that heading are religious BUT IT DOES NOT LIST ALL THE RELIGIOUS WARS CITED !!
The index heading OMITS (JUST for example) :
·
Arab Israeli Wars
·
Sultanate Wars
·
Holy Roman Empire Wars
·
Jewish Revolts
·
Muslim Wars
·
Sikh Wars
And the body of the encyclopedia goes into great detail about the religious aspects of those wars. So how many wars are religious BASED ON THE CITED VOLUME ? 617 !! That is 35% !!
BASED ON THE VOLUME CITED BY THEISTS - 35% of wars are religious.
3) So how many died in religious wars ? For a start, A&P list UNKNOWN CASUALTIES against 350 of the 617 religious wars. Of the KNOWN RELIGIOUS wars - the total is around 55 - 60 M. Apply “pro rata” gives around 130M.
4) Is the total number of deaths meaningful ? This method equates 1M dying when the population was 10M (10% of the planet) as being the “same” as 1M dying when the population was 1Bn (0.1%). So what PERCENTAGE of the planet died in religious wars ? Answer (applying pro rata for unknown deaths) AROUND 16.5%. IN TODAYS POPULATION TERMS RELIGIOUS WARS HAVE KILLED 1.3BILLION PEOPLE.
5) How do religious war deaths (from (4)) break down by religion ?
- Christianity 720 Million
- Jewish 150 Million
- Muslim 328 Million
ARE WE CLEAR NOW ? Remember - THIS IS BASED ON THE VOLUME THAT YOU CITED.
6) You state "That's only 7% of all wars in recorded history! 7% isn't even close to a majority. " - Leaving aside that it isnt 7% but 35% - THAT WASNT THE QUESTION !! Your question was "Is Religion Responsible for the Most Wars and Deaths in History" - based on my reading - AND THE COMMENTS FROM THE AUTHORS THESEMLVES - yes it is. You are confusing "which is the most common cause of wars" (of all the causes which cause has resulted in the most wars / deaths , i.e. Religion) with "Has religion cause the MAJORITY of wars / death" (i.e. more than 50%). BASED ON THE SOURCE YOU CITED (!) YES RELIGION IS Responsible for the Most Wars and Deaths in History"
So please - if you are going to cite sources - I SUGGEST THAT YOU READ THEM FIRST - THEY MIGHT JUST CONTRADICT YOUR CLAIM !
You first question whether we can determine the numbers of people killed in wars, saying we have "little idea" of such historically. Then you argue that your calculations are more accurate than mine. That's a contradiction, not "critical thinking."
Re: 2-6
In your previous comment above, you calculated 25%. Now you're saying 35%. Which is it? You seem to be all over the map. Why don't you settle on a number (or at least a methodology), then we can discuss? A closer reading of my arguments and sources may also help you unravel your misunderstandings.
If you were to add up every person that died constructing pyramids or other religious monuments, every tribesmen that died for their various beliefs... Every sacrifice, every slave. Then yes, religion has killed more than anything else known to man.
