Revision in history is done all the time.
There's *no* conspiracy in it;
And it's not evil in its intent.

As historians learn new information, adjustments are made to the record. This happens for many reasons. In the ancient world, or up until fairly recent times, it's usually do to finding new information that was previously undiscovered. A new discovery may have been made that adds to the record. For example, a new archaeological dig uncovers new material previously unknown. A family releases documents that it has held onto for multiple generations. A new piece of work from an artist is discovered. A stolen piece has been recovered. A restoration uncovers something previously hidden underneath. All of these reasons, and more, can change the historical record.

One clear example is the Renaissance. Most were taught that it was a time of great advances. But, the historian has now looked at *all* the people, not just the artists, the courts, and the merchants - most of whom were male. But, when they viewed the lives of the women of the time, we see that there was a real *loss* of social, economic and political power.

That change in perspective, and the resultant change in the concomitant story causes what one historian labeled a "double vision." While real gains were made in multiple areas, there were tremendous losses for 1/2 of the population! This is historic revision. It's what most of us never learned in school. But, new information leads to a new story.

In more modern times, the reason is more obvious. Records are kept locked up and secured by the government until a certain number of years after the person's death. This is for many reasons - privacy of the family and national security to name a few. When these records are released, it changes the previous knowledge. When the knowledge changes, so does the previous story -- the history.

Historic revision has *always* gone on. The history of history - called historiography - tells of this compelling case. Simply look up a piece of history that you recall from your school years, and google it with historiography in the google search. You'll find multiple schools of history, with their own angle, and how the study of history has changed over time. So, even the change in the *study* of how history is conducted changes the story!

There is *no* evil intent involved in historic revision. Unless, of course, you think the advent of knowledge itself is evil! LOL! If so, nothing I, or anyone else says will convince you of anything.

The study of history prior to 1700 at that school was a result of budget cuts -- and *not* some evil intent as some originally assumed. Neither is historic revision. It's the historian's job to correct the record when the evidence requires that change.

But, Americans sure do love a conspiracy theory! After all, the American Revolution was born of one! It's in our blood.
But, the historian needs evidence.

Peace!
