Final answer:
The Compromise of 1877 ended the Reconstruction era, led to the establishment of Jim Crow laws, and had negative impacts on civil rights in the South, like reducing Black political representation and not confirming civil rights laws.
Step-by-step explanation:
The Compromise of 1877 had a significant impact on southern policy by leading to the end of the Reconstruction era. One key result was the enactment of Jim Crow laws, which codified racial segregation and disenfranchised African Americans across the South. Although the Compromise resulted in the withdrawal of federal troops and the cessation of federal efforts to enforce civil rights, it did not lead to the South becoming predominantly Republican, nor did the Supreme Court confirm civil rights laws. In fact, the high court would later eviscerate the Civil Rights Act of 1875. Moreover, the potential for African Americans to hold public office, which was a result of the Reconstruction era, diminished significantly as a consequence of the Compromise.
