Jim Crow was the name of the racial caste system which operated primarily, but not exclusively in southern and border states, between 1877 and the mid-1960s. Jim Crow was more than a series of rigid anti-Black laws. It was a way of life. Under Jim Crow, African Americans were relegated to the status of second class citizens. Jim Crow represented the legitimization of anti-Black racism. Many Christian ministers and theologians taught that Whites were the Chosen people, Blacks were cursed to be servants, and God supported racial segregation. Craniologists, eugenicists, phrenologists, and Social Darwinists, at every educational level, buttressed the belief that Blacks were innately intellectually and culturally inferior to Whites. Pro-segregation politicians gave eloquent speeches on the great danger of integration: the mongrelization of the White race. Newspaper and magazine writers routinely referred to Blacks as niggers, coons, and darkies; and worse, their articles reinforced anti-Black stereotypes. Even children's games portrayed Blacks as inferior beings (see "From Hostility to Reverence: 100 Years of African-American Imagery in Games"). All major societal institutions reflected and supported the oppression of Blacks.
The Jim Crow system was undergirded by the following beliefs or rationalizations: Whites were superior to Blacks in all important ways, including but not limited to intelligence, morality, and civilized behavior; sexual relations between Blacks and Whites would produce a mongrel race which would destroy America; treating Blacks as equals would encourage interracial sexual unions; any activity which suggested social equality encouraged interracial sexual relations; if necessary, violence must be used to keep Blacks at the bottom of the racial hierarchy. The following Jim Crow etiquette norms show how inclusive and pervasive these norms were:

1. 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.

2. 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.

3. Under no circumstance was a Black male to offer to light the cigarette of a White female -- that gesture implied intimacy.

4. Blacks were not allowed to show public affection toward one another in public, especially kissing, because it offended Whites.

5. 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."

6. Whites did not use courtesy titles of respect when referring to Blacks, for example, Mr., Mrs., Miss., Sir, or Ma'am. Instead, Blacks were called by their first names. Blacks had to use courtesy titles when referring to Whites, and were not allowed to call them by their first names.

7. If a Black person rode in a car driven by a White person, the Black person sat in the back seat, or the back of a truck.

8. White motorists had the right-of-way at all intersections.

Stetson Kennedy, the author of Jim Crow Guide, offered these simple rules that Blacks were supposed to observe in conversing with Whites:

1. Never assert or even intimate that a White person is lying.
2. Never impute dishonorable intentions to a White person.
3. Never suggest that a White person is from an inferior class.
4. Never lay claim to, or overly demonstrate, superior knowledge or intelligence.
5. Never curse a White person.
6. Never laugh derisively at a White person.
7. Never comment upon the appearance of a White female.
