On another forum, a statement was made that governments hunting mutants had been a thing from the beginning. I've been rereading a wide range of Marvel titles from FF#1 (I'm currently in 1975), including Uncanny X-Men, and it seemed to me that oppression usually was in the form of mob violence. So, my question, when was the first appearance of organized, official oppression of mutants in the comics?
The first hint of it that I can see is Uncanny X-Men 1.135; when in the wake of the X-Men's near-disastrous attempted-infiltration of the Hellfire Club, Black King Sebastian Shaw begins lobbying Senator Kelly to initiate a Sentinel Program. The most direct evidence of its origin that I can see is Senator Kelly's hearings in Uncanny X-Men 1.141 (the first half of "Days of Future Past").
So my question: whether in the X-titles or out, what's the first time we're shown a government as a deliberate mutant hunter/oppressor?
