Jim Crow laws: segregation and social etiquette

1st - The Jim Crow laws is laws to prevent racism in videos or in costumes and such

2nd - The aim for these laws was to shut down all attempts carry out a racist act, such as costumes and videos speeches and were state and local laws that enforced racial segregation in the Southern United States. Enacted by white Democrat-dominated state legislatures after the Reconstruction period, in the late 19th century, the laws were enforced until 1965, as I just said in question 1

3rd - in this picture we can see a class, or even a school separated from the normal white classes or Schools, and in this picture, we can also see the children not having a lot of books and such, instead they would get the books from white schools that had been discarded

4th - the etiquette was kind of the social rules, those rules not written down, almost like when you are sitting at a table and doing and these things such as eating with forks and knifes, that just a thing you do, like such as --- A black male could not offer his hand (to shake hands) with a white male because it implied being socially equal. Obviously, a black male could not offer his hand or any other part of his body to a white woman, because he risked being accused of rape. Blacks and whites were not supposed to eat together. If they did eat together, whites were to be served first, and some sort of partition was to be placed between them. Under no circumstance was a black male to offer to light the cigarette of a white female -- that gesture implied intimacy. Blacks were not allowed to show public affection toward one another in public, especially kissing, because it offended whites. Jim Crow etiquette prescribed that blacks were introduced to whites, never whites to blacks. For example: "Mr. Peters (the white person), this is Charlie (the black person), that I spoke to you about."
