Your source is the University of Texas at Austin....Austin, as in "hotbed of PC", especially near the UT campus. A lot of the people on faculty at Texas are raving liberals, as shown by author Moneyhon, whose definition you link to, with his first, strategically misdirective and inaccurate, sentence:
BLACK CODES. Black Codes were the laws passed by Southern state legislatures....
Mr. Moneyhon, if he is well-read, is probably aware that black codes were not the exclusive province of Southern legislatures, although they wrote them; they had good company in a number of Northern and Midwestern States, including your own favorite.
And if you had read those seven grafs from Fehrenbach that I pointed out to you above, you would have seen that the acceptance of "equality" for the Negro was not accepted in Northern States at all, and that restrictions on black suffrage were the rule in the upper Midwest. It was only Radical Republican opinion that engaged the concept of "equality" and unrestricted black suffrage, and then only in the South, as a regional punishment for the Southern States.
Or have you read that post yet? Q. v., supra. Et cetera.
And I'm still waiting for your answer to the other question, wise guy.
My source was one used by TexConfederate in the past. What's good for the goose is good for the gander.

The difference being that while the pre-war laws in the North may have made conditions for Blacks in some states almost as bad as they were for free Blacks in the south, conditions were changing. Blacks were gaining more rights post war. But the south was moving in the other direction, making their already restrictive laws even more restrictive, and trying to return slavery as much as possible.

Patience is a virtue.
