The Third Crusade, 1189–92, followed on the capture (1187) of Jerusalem by Saladin and the defeat of Guy of Lusignan, Reginald of Châtillon, and Raymond of Tripoli at Hattin. The crusade was preached by Pope Gregory VIII but was directed by its leaders—Richard I of England, Philip II of France, and Holy Roman Emperor Frederick I.(Emphasis mine)
If I picked out the wrong Richard then feel free to moan at me, my knowledge of our old rulers is at about the same level as my knowledge of structural engineering, ie virtually zero.
Anyway, definatly something to watch if you have some time or bandwidth* spare.
