How did southern states’ laws under reconstruction affect freed enslaved persons?

During Reconstruction, Southern states passed the Jim Crow laws, with the aim of restricting African American rights in their territories.

Explanation:

The Jim Crow Laws were a series of ordinances and bylaws promulgated generally in the southern states of the United States between 1876 and 1965. These laws, which constituted one of the major elements of racial segregation in the United States, distinguished citizens according to their race and, while admitting their equality of rights, they imposed segregation of rights in all public places and services.

The largest ones introduced segregation into schools and most public services, including trains and buses.  School segregation was declared unconstitutional by the United States Supreme Court in 1954 in the ruling in Brown v. Board of Education. The other Jim Crow Laws were abolished by the Civil Rights Act of 1964.

explanation:

the addition to geographic boundaries that might have  kept the people of the huang river civilization from traveling to far distance region is that they had learned about the other river valley civilizations but feared contact would bring invasion.
