Most deadly wars ever

[jusplay4fun]

Since there is a religious theme here, let me wish a Merry Christmas to all on CC.

For those who prefer, Happy Holidays and enjoy whatever one you choose to celebrate and recognize.

As for me and my household, we will choose to serve the Lord, live joyfully, be kind to strangers, respect others, and try to be patient.

And Happy New Year, too.

I like that you used the phrase "in [religion's] name." By my reckoning, most wars are not engaged in for any reason other than the accumulation of power and/or wealth. They are dressed up in different things and one of such things may include religion. I suppose the Crusades were started for purely religious reasons, but apart from that I fail to see a situation where religion was the primary driver and motivation for war.

Tl;dr version - "Hey y'all, I'm the Buddha reincarnate, let's go attack these people over there so I can get more money and power... erm, I mean for my religion. Yeah, religion, that's it!"

30 years war...?

This link seems to provide a good summary of information about the Thirty Year War:

And I think that both theGreekDog and DoomYoshi made some good points in their posts.
