Did attitudes regarding African Americans change as a result of the Civil War?

Explanation:

no it did not

The Emancipation Proclamation in 1863 freed African Americans in rebel states, and after the Civil War, the Thirteenth Amendment emancipated all U.S. slaves wherever they were. As a result, the mass of Southern blacks now faced the difficulty Northern blacks had confronted—that of a free people surrounded by many hostile whites. One freedman, Houston Hartsfield Holloway, wrote, “For we colored people did not know how to be free and the white people did not know how to have a free colored person about them.”

the federalist party which advocated strong centralization dominated the united states government till 1800. so 1800 election transformed the power from one party to another party for the first time and was thus a turning point in american history. so jefferson called it "revolution of 1800".
