Richard died in battle - the last English king to die in battle. He was killed by the soldiers of the usurper king, Henry VII (who did not fight - just hid behind his soldiers). When this kind of death took place, the body was put on display for several days to ensure the population knew that the king was dead. Richard, in very unusual fashion, was mutilated after death, displayed, and then thrown into a hastily-created ditch within a friary. We don’t know whether he had a Christian burial.
Thanks, but I was wondering how his remains were reburied.
