Shakespeare's only attempt at being a real historian -- The Famous History of the Life of King Henry the Eighth

Most of Shakespeare's histories do actually have some attempts at historical analysis in them, and, of course, Shakespeare was obviously an accomplished amateur historian. However, almost all his histories depart very, very far from actual, true history, to some extent, because of lack of actual historical data to base them on, to some extent, because of his obvious professional need to create drama from history, whether it was actually present, or not, and, sometimes, because of a need to accomodate political pressure and social pressure to support contemporary political and social values. The one exception to this general rule that Shakespeare wrote dramas based very loosely on actual history, not history itself, is certainly his very last play, The Famous History of the Life of King Henry the Eighth. The title itself suggests that this play is an exception in many ways to his many other historical dramas, almost explicity stating that this work is actually biographical in nature, and not fiction, at all.
