Final answer:
The Enforcement Acts were designed to protect African American voters from Klan violence and to reinforce their voting rights, established by the stated acts, which the federal government could enforce. They included provisions for federal oversight of elections and presidential authority to suppress civil rights violations.
Step-by-step explanation:
The Enforcement Acts of 1870 and 1871, also known as the Force Acts, were passed to protect the voting rights of African Americans and to combat the violence of the Ku Klux Klan.
The first act enforced penalties for anyone who interfered with a citizen’s right to vote and strengthened federal supervision over elections.
The second act established federal oversight of elections, while the third, the Ku Klux Klan Act, granted the president additional powers to suppress violent infringement of civil rights, including suspending habeas corpus. However, the Supreme Court later declared some provisions of the acts unconstitutional.
