Reason for jim crow laws and the black codes to end

In 1964, President Lyndon B. Johnson signed the Civil Rights Act, which legally ended discrimination and segregation that had been institutionalized by Jim Crow laws. And in 1965, the Voting Rights Act ended efforts to keep minorities from voting. This allowed minorities, such as African Americans, to vote in favor of themselves to prevent racist laws. Hope this helps you!
