Final answer:
The Civil War led to the formal end of slavery, but black servitude continued in altered forms due to Black codes, Jim Crow laws, and the actions of the Ku Klux Klan.
Step-by-step explanation:
Impact of the Civil War on Black Servitude
The impact of the Civil War on black servitude led to significant changes but did not completely abolish the conditions resembling servitude for African Americans. Although the Thirteenth Amendment formally abolished slavery, the implementation of Black codes in the South sought to maintain black servitude under different guises, such as sharecropping and other forms of coerced labor. Additionally, the emergence of the Ku Klux Klan and the enforcement of Jim Crow laws by the end of the 1870s ensured that black servitude continued to exist, albeit in an altered state. Thus, option 2) 'Black servitude continued to exist but with some changes after the civil war' most accurately reflects the situation following the Civil War.
