For a list of deaths by religion that is interesting to read though inaccurate – as all such lists must be since the count of deaths and the certainty of their cause can never be verified – go here.

Note: Wars have been waged by regimes which were officially atheist – such as those waged by and in Soviet Russia – but no war has ever been fought (or massacre carried out) in the name of atheism, or in order to advance or impose atheism.

*From Wikipedia:

In 1985, John Lenczowski, director of European and Soviet Affairs at the United States National Security Council, wrote an article in The Christian Science Monitor in which he stated that the “number of people murdered by communist regimes is estimated at between 60 million and 150 million, with the higher figure probably more accurate in light of recent scholarship”.
