Certainly! Here’s a revised version that enhances clarity and corrects punctuation and grammar:
The biggest challenge the nation faced during Reconstruction was abolishing slavery and ensuring equal rights for former slaves. The government enacted the 13th, 14th, and 15th Amendments to abolish slavery and provide African Americans with civil rights. This was the most significant challenge because many people in the South resisted these changes and continued to uphold discriminatory practices. Groups like the Ku Klux Klan actively fought against the recognition of African Americans’ rights. It was difficult to change long-standing rules and traditions that were unjust, particularly in a society where widespread opposition existed in the South.
