How did the jim crow laws fortify and perpetuate, or continue, racial discrimination in the united states?

Jim Crow laws were laws passed in the Southern states in the US after the era of Reconstruction. These laws perpetuated racial discrimination because they resulted in segregated public facilities. For example, Jim Crow laws lead to separate schools, churches, parks, bus stops, restaurants, and movie theaters for black and white citizens.

These segregated facilities continued to promote racial discrimination, as the facilities for black American citizens were inferior to those for white citizens. This was especially true when it came to public schools.

The  pan-african movement  was an "emotional, cultural, psychological and ideological  movement  that began among the  african  dispora in the western hemisphere, for a closer  purpose, so that  african  people could feel secure, attain political, economic as well as psychological power visa vis other races or world regions" .
