Jim Crow laws started after the Reconstruction period (1863-1877) and served to keep now former slaves, the African-Americans, from having equal rights as the white people had.
Based on the truthless argument of "separate but equal" these laws created spaces that black people did not have access to, leaving the best positions in many places for the whites. The separation was the way white supremacists chose back then to enforce their violence upon black people.
The "equal" in the aforementioned phrase was empty as violence against African-Americans was explicit; lynchings of black men, for example, were common. Black American citizens didn't have their civil rights respected, not in practice (the right to vote was constantly disrespected) nor in theory (Jim Crow laws violated many civil rights).
