Magneto's back story wasn't established until way, way after Lee and Kirby left the book. He was mostly just an evil mutant with his group of evil mutants, and the X- men were the good mutants standing in his way. Roy Thomas has a little of the future paradigm in his collaboration with Neal Adams in issue 63, but it's more that Mags wanted to rule the world with evil mutants, not free all mutants from humans.
Claremont established his Jewish backstory in Uncanny X-men 150. Even in earlier appearances in Claremont's run (104, 113), Magneto is still just a super villain who is trying to beat the X-men and take over the world.

Reply to comment by amadeus2490 in TIL Stan Lee made the X-Men mutants because he didn't want to come up with a reason for their super powers, instead they were just born with them. Additionally the 1963 comic was initially a flop until the 1975 reboot by Len Wein and Dave Cockrum. by jamescookenotthatone
