Imagine you are the devout Catholic king of a famous country until one day you are killed in a battle, which your side loses. Imagine further that the guy who led the other side in the battle becomes king. That much seems seems fair enough. The other guy's son also becomes king after him, which also seems fair. However, one of the most important things the son does is to start a new religion that everybody in the kingdom is forced to join. Meanwhile, your body is never recovered from the battlefield, and remains lost for centuries. Finally, your body is found, under a parking lot. [A reader kindly points out that Richard's body was indeed recovered from Bosworth field and buried in Greyfriars church, Leicester. Henry VIII, the son of the guy who defeated Richard, dissolved the friary in 1538 and sold the real estate to developers. The developers demolished the buildings and sold off the stones, making it much harder to figure out where Richard's body lay, which is how eventually a parking lot came to be placed above it.]
Everyone agrees that your bones should be interred with suitable ceremony. Would you want that ceremony to be according to the rites of the Catholic religion, the religion you practiced devoutly, or according to the rites of some crazy new religion started by the son of the guy who defeated you in the battle in which you got killed? You'd want Catholic rites, right? Well, so undoubtedly would King Richard III (1452 - 1485 AD), to whom all the things in my imaginary story actually happened, but that's not what he's going to get.
