What Really Happened In The Past?

It is a broad, but fascinating topic for our round table this time. In this hectic time of change, with major new conspiracies regularly being unearthed, we should be reminded of, and appreciate, those who tried to preserve an accurate telling of past events in the face of cover-ups, white-washes, propaganda and blatant ignorance.

Many things in history did not happen as we are told in state education and main stream sources. What example do you have? Which topic do you find most intriguing?
