Literally a TV show about interplanetary space empire ruled by an evil wizard, so... very likely it will deviate from reality by leaps and bounds.

Its entertainment. It happens to be entertainment with good politics, but its still just a big dumb show for the hogs. If you want history, read history. If you want politics, go to a fucking meeting full of other people interested in doing politics. If you want a fairy tale about some cool dudes cosplaying as that one Russian guy who successfully led a revolution, then that's fine. Everyone wants a bit of entertainment now and then. But that's what that is.
