Incidentally, for those of you who may be wandering, before she became co-opted as a Jedi potential, Leia's original post ep. VI plot (note NOT post ROTJ plot, because once epiosde VI became ROTJ that finished this idea) was for her to follow in her Mother's footsteps as Luke followed (kinda!) in his father's by becoming Queen of her people (remembering at the time there was no need for her to have been adopted as in this plotline she was not Luke's sister).
Though quite who she was ruling, seeing as they got blown up, I dunno.
