So when it comes to our stories, especially the longer fiction, how does our world's history affect the time in which you are specifically writing? No world is unaffected by its history so what past events still haunt your people in your tale? What do they commemorate? What are their triumphs and disasters?
Who records the history officially and is this challenged? Is the official history backed up and if so how and who by?
What is important, socially and otherwise, to the peoples you've created on the page? Should be fun finding out!
