Black codes were enacted right after the Civil War.
Explanation:
Black Codes were laws created by former Confederate states after the Civil War to weaken the status of blacks in those states. Laws began to be created in 1865 with the passage of the 13th Amendment to the Constitution in the United States, which officially liberated all black slaves.
Black Codes had time to be created for more than a year before Congress, with a Republican party opposed to slavery in the majority, passed the Civil Rights Act and the 14th and 15th Amendments to the Constitution. In the late 1870s, however, the position of blacks weakened again as racist extremism, led by the Ku Klux Klan, intensified.
