This is more of a response to this post that spurred me to write this because this is a question that has been bugging me for a while.
When I started to look into history a while ago, I used to think that our understanding of history is done with the intention of being as objective as possible and state what actually happened instead of giving our interpretations of what happened or what might have happened or about the people that were involved.
I know that history is not something that is set in stone like a hard science and it is something that is continuously being updated and examined as it involves our understanding of historical events and our interpretations of the different perspectives of historical events as some of the artefacts that also rely upon are documents that were written by the people of that time or written things even after that time has passed like
But as I delve deeper into my understanding with different parts of human history, I keep on realising more than some of the things that I thought about history were debunked or updated, or some parts of history were overly focused upon while the others were neglected or given little attention
For example:
I am getting the impression that is the subject of either politicising history for personal agendas, or from the work of amateur historians whose inaccurate interpretations of history get into pop culture
This is a truly vast topic, and one that historians – and indeed outsiders to the profession – argue about constantly; it's rare to find a book on historiography that doesn't include at least a chapter on the issue of objectivity. So there is very definitely more to say. But historians struggle with the concept of being "objective" because it's an absolute in a world, and in a discipline, in which absolutes don't exist.
To get something of a handle on the consequences, and while you're waiting for fresh answers to your question, you might like to check out some existing resources here on AskHistorians, starting with this recent note of mine:
