In this new three-part series for BBC Two, Dr Thomas Asbridge presents his revelatory account of the Crusades, the 200-year war between Christians and Muslims for control of the Holy Land. The story of the Crusades is remembered as a tale of religious fanaticism and unspeakable violence, but now fresh research, eyewitness testimony, and contemporary evidence from both the Christian and Islamic worlds shed new light on how these two great religions waged war in the name of God.
