I agree that history is usually written by the victors, but not always. This is a thought I have been playing around with in my mind. I can go into almost any hotel in America, and find a book about iron age Jewish history. It may not be completely accurate, but the Bible is a rather detailed description of iron age Jewish history. Jews were not victorious.
Jews cared about history, wrote about history, and survived. For the most part, the victors did not do all three. Modern Egyptians cannot read hieroglyphics, modern Iraqis cannot read cuneiform, and neither care particularly much about pre-Muslim religious practices. Even their own knowledge about their ancestors is filtered through Jewish historians.
Then there is the pseudo-history of the Lost Cause. For about 100 years, most of the writing about the Civil War was by the losers who wanted to reframe the war as some sort of heroic lost cause, and not as a defense of the vile institution of slavery. The Daughters of the Confederacy invested heavily into teaching children about the Lost Cause. Had the civil rights movement not come along, that would still be established history. But, certainly not the history as written by the actual victors.
Reletor, you make good, interesting points, and I am sorry if I have muddied the issue. Welcome to the forum, and I hope you keep posting.
