That is the question posed by “Star Wars and History,” a book planned for 2013 by the publisher John Wiley & Sons. In an e-mail posted in June, Nancy Reagin, a history professor at Pace University, and Janice Liedl, an associate professor of history at Laurentian University in Ontario, asked their peers to submit essays that explore the parallels between world history and Star Wars history."

It is officially sanctioned by Lucasfilm, though, and much of it will be about mining "Lucas’s notes and input about what patterns of history actually did go into Star Wars or influence his thinking." I expect it will be chock full of propaganda as a result...
