I am reminded of this passage from the Ministry of Time:

“You misunderstand how history works,” she said. “History is not a series of cause and effects which may be changed… It is a narrative agreement about what has happened and what is happening. History is what we need to happen. You talk about changing history, but you’re trying to change the future.”

And I might point out that it isn’t what history is written that is important, but what history is studied and taught.
