Gringo,
You don't need the whole history, just a few highlights from here and there.
The story of William Wallace, the real Braveheart. A real guy from Scotland. He wanted Scotland to have independance from England. A right bloody story.
If you want mans inhumanity to man check out the way the killed the poor guy. It was common practice to kill people for maximum pain and agony back in the good old days before Satan was cast down.
Back when we were still a colony here in the US a popular way to off a wrong doer was to have them straddle a saw horse with a blade on it and then put weights on them until they were cut in two.
