Its all about controlling history. That is what the Northern teachers tried to do to Southern children during reconstruction (which created the backlash of the "Lost Cause").

This is demonstrated in two works of art, Shakespeares "The Tempest" where Prospero alone seems to understand that controlling history enables one to control the present—that is, that one can control others by controlling how they understand the past; and Orwell's "1984" where Orwell demonstrates how the Party, by controlling history, forces its members into lives of uncertainty, ignorance, and total reliance upon the Party for all of the information necessary to function in the world.
