Which religion has killed the most people in history?
<|assistant|>
Christianity is arguably the most violent religion in history, primarily due to the persecution of non-believers, and multiple wars waged in the name of Jesus. However, most of the deaths caused by Christianity happened during the Crusades (1095-1291 CE) and the Inquisition (1235-1600 CE) in Europe, meaning the vast majority took place hundreds, if not thousands of years ago, whereas contemporary Christianity is less violent.
 
In contrast, Muslims have caused the most deaths in contemporary history. Islamic fundamentalists, who take the Quran and Hadith very literally, have led numerous offensive campaigns to expand the religion, often through violent jihad and military conquest. For instance, since 1947 CE the Muslim World has been embroiled in conflicts in the Middle East and South Asia that have resulted in the deaths of millions.  In more recent years, Islamic extremists from the Islamic State (IS), Boko Haram, and Al Qaeda have led violent campaigns and continue to spread terror and destruction.

At the same time, while the world's two largest religions have been linked to some of the greatest violence in history, there are countless religions and faiths that promote harmony and peace, with very few instances of violence being associated with them. Buddhism, Hinduism, Taoism, and many other religions have not been involved in any widespread military campaigns or violent activities to spread their beliefs, indicating that it is generally the extreme fundamentalists that have caused conflicts around the globe, and not the religion as a whole.
