History of Religion via Maps

One of my teacher-students, Jessica May, just pointed out the site mentioned below showing via maps how the history of religion has grown.  Believe it or not, it was one of my first posts back in 2008.  It details how the geography of religion evolved over the centuries, and where has it sparked wars. The map gives us a brief history of the world's most well-known religions: Christianity, Islam, Hinduism, Buddhism, and Judaism. Selected periods of inter-religious bloodshed are also highlighted.
