Why did congress pass the enforcement acts between 1870 and 1875?

Congress passed the Enforcement Acts between 1870 and 1875 to protect African American's political rights.

Explanation:

The Enforcement Acts were a series of three laws passed by Congress between 1870 and 1871.

They were criminal codes designed to protect the voting rights of African Americans, to perform their duties, to serve in juries and to receive equal protection of the laws. Under the presidency of Ulysses S. Grant, the laws also allowed the federal government to intervene when states did not act to protect those rights.

These acts were passed after the ratification of the Fourteenth Amendment, which gave full citizenship to any person born in the United States with no distinction of race, and the Fifteenth Amendment, which prohibited racial discrimination in voting. Until that time, the lives of all newly liberated slaves, as well as their political and economic rights, were threatened. This threat led to the promulgation of these laws.
