If you want one nice, “one size fits all” historiographic model that is a good starting point to examine the individual writer’s bias, it is that history is not written by winners, but by writers. For most of history the writers came from a distinct social class, not necessarily at the economic and political top, but far from the bottom. They were also highly educated and thus concerned with the preoccupations of the highly educated in that particular society.
That being said, I have experienced something similar to what @BeenThereSaidThat has posted. I have seen “historical events” cited that do not reflect my memory of that particular event. I have also seen history as I learned it, being revised.
For example: What happened at The Alamo in 1836, and why? When I was in grammar school, I learned it was a group of citizens of the Republic of Texas defending themselves against an incursion by the Mexican army. Another version would have one believe it was Mexico trying to prevent American settlers from forming a break-away government in a Mexican territory.
