Why were three amendments added to the constitution during reconstructon?

During Reconstruction, three amendments—the 13th, 14th, and 15th—were added to the U.S. Constitution to address the rights of newly freed slaves and to establish a foundation for civil rights. The 13th Amendment abolished slavery, the 14th granted citizenship and equal protection under the law, and the 15th aimed to secure voting rights regardless of race. These amendments were crucial in attempting to integrate African Americans into society and ensuring their legal rights after the Civil War. Overall, they represented a significant shift towards greater equality and civil rights in America.
