How did the political factors of the reconstruction lead to the civil rights movement?

The political factors of Reconstruction, such as the establishment of the 14th and 15th Amendments, aimed to secure rights for formerly enslaved African Americans but were undermined by systemic resistance, including the rise of Jim Crow laws and the withdrawal of federal troops from the South. As Southern states enacted discriminatory practices to disenfranchise Black citizens, disillusionment grew among African Americans and their allies. The failure to protect these rights galvanized organized efforts, leading to the Civil Rights Movement of the mid-20th century as activists sought to challenge segregation, discrimination, and advocate for full equality under the law.
