What do you think of the relationship between historical and literary works and real history?

Oh, my understanding of this is simple: to sum up, there are both connections and differences. Literary works with historical themes are based on the real historical background, but there are artistic processing and virtual illusory complex and artistic sublimation according to artistic needs. On the other hand, real history has nothing to do with literary and artistic works on historical themes. It was a natural fait accompli under the historical conditions at that time. Because literary and artistic works with historical themes are often created after historical reality, that is, in chronological order, the former will not be affected by historical works at all. Generally speaking, real history is an irreversible fact and event, while literary and artistic works are cultural products of different genres that can be reprocessed and fabricated.
