Whose History? There are two meanings to the expression "the history of X":
1. The series of events
2. The [literary -- though we may imagine a day in which it will be cinematic, or use some other medium] product presenting the series of events.
We call both of these meanings "the history of": "Have you read the history of X?" "in the history of X, R and S happened before we got where we are".
Microhistories are a good hook. StreetlightX mentioned the history of salt. What is "the history of salt"? It is a series of events, and a book. What links both meanings is the intent of an author; someone saw a reason to write a book about the history of salt. (I haven't read it, but I have little doubt that it must be interesting!).
As discoii mentions, there can be no objective account of history, for many reasons. One of them is that the selection of facts (the so called "series of events") proceeds according to biased viewpoints. Another is that the presentation of these facts is also biased. And even the reader is biased. But the concern here is not bias, it is about the identification of what it is about. The history of salt is not about salt; it is about our interest in salt. As Borges would say, there are infinite histories which have not been written and which will never be written, because no one -- not a single human being -- will identify that particular series of events as being meaningful to the extent that it spurs the writing of a history.
So, to sharpen up the concern that led me to the OP: what is it that leads people to write histories of X? This is a personal decision; in theory, the historian has absolute freedom. But there must be some common trait or traits between salt, clothing, mammals, France, science, the West, the Universe and childhood; these are the stuff about which histories are written of.
The answer certainly points up to some movement of the historian's being towards the preservation (or, the bolstering up) of something cherished. People write histories because (a) they thing the subject is meaningful, (b), they want other people to know about it, and (c) they think that, by telling other people about it, they are participating in the life of the subject. The historian creates and enters the history he writes.
There is more to be said, but I'm not sure what. It's a meditation in process around here (in my mind). I don't know where it will lead.
