Explanation:

The Civil Rights Movement did not suddenly appear out of nowhere in the twentieth century. Efforts to improve the quality of life for African Americans are as old as the United States. By the time of the American Revolution in the late eighteenth century, abolitionists were already working to eliminate racial injustice and bring an end to the institution of slavery.The Thirteenth Amendment officially outlawed slavery and went into effect in 1865. After the Civil War, during the period known as Reconstruction, the passage of the Fourteenth and Fifteenth Amendments established a legal foundation for the political equality of African Americans.
