Deaths over history: religious vs. nonreligous
I heard a while back that more people had died in the name of Jesus than in the name of Hitler. I’d always wondered if it was true, it seemed perfectly plausible given the persistence and viciousness of the Vatican during the Crusades. Unfortunately, I had found it difficult to find a number of deaths from the Crusades. But, I found in Google Answers, this webpage that chronicles numerous human conflicts and includes a category for religious conflicts. The numbers are hazy, of course, when we’re speaking about conflicts hundreds or thousands of years ago when death tallies were not a priority or of mild interest like they are today.
In short, 809 million people have died in religious wars. That’s nearly a billion people.
LENGTHY RESPONSE:
Oftentimes, a retort is that secular ideals and Godless Communism have killed many more. It is true that Stalin, among others, slaughtered his own people by the millions during the industrialization of Soviet Russia. By comparison, 209 million have died in the name of Communism. Some 62 million died during World War II, civilian and military, on all sides. Conclusively, more people have died in the name of religion than in the name of Communism or Hitler, or the two combined times two.
Best estimate of the deaths caused by the Crusades is: 3 million.
Several sources place the number as high as 9 million and as low as 1 million.
You really should read the whole thing including the comments, especially since if you had read just a little further along, you would have found something more authoritative.
Always read the comments and the remarks, whether it is some internet source like this one or
www.lucianne.com or a financial statement.
The “billion” number you quoted was probably the entire population of the whole hemisphere / “quartersphere” or region for the entire 200-year time period in question. Or thereabouts. And since everybody eventually died, that’s what the “alleged originator” included. Not good scholarship on his part.
This is the link to what you quoted:
bookrate.wordpress.com/2006/07/22/deaths-over-history-religious-vs-nonreligous/
You quoted a source which the commenters immediately repudiated.
Here is what one commenter said:
“The TOTAL population back in the time of the Crusades and Inquistion was no more than 150 Million and the Black Death claimed about 50 Million. So these estimates are really laughable.”
Anyway, go here and take a look at the detailed analyses.

Here is another interesting quote that took exception to the billion number:
“The total number of deaths estimated to lie at the feet of humanity’s poor practice of Christianity is approximately 17 million. This number would include ancient wars, the Crusades, the Inquisitions, various European wars during the Middle Ages, and witchcraft trials.”
