Medieval history scholar Dr Thomas Asbridge presents his account of the Crusades, the 200-year war between the Christians and Muslims for control of the Holy Land. It's remembered as an incredibly violent battle with roots in religious fanaticism, but fresh research, eyewitness testimony and contemporary evidence from both factions shed new light on how two religions fought in the name of God. Among other story lines, the three-part miniseries traces the epic journey of the crusaders as they marched from Europe to Jerusalem; offers an examination of the Third Crusade and the legendary Richard the Lionheart and Muslim sultan Saladin; and reveals that the wars were not decided on the sacred ground of Jerusalem, but in Egypt.
