What can you imply from the history regarding Jim Crow laws

The Jim Crow Laws were created in 1876 simply to segregate black people from the white population. Some English Dictionaries define ‘Jim Crow’ as the name for an implement that can straighten or bend iron rails; or, along with ‘Jim Crowism’, systems or practices of racial discrimination or segregation. The American English Dictionary suggests that the name only emerged in dictionaries in 1904, but it was clearly used generally in 1876, at least.
