The era that involved legislation enacted by the radical Republicans was the Reconstruction Era, which took place in the United States following the Civil War from approximately 1865 to 1877. During this time, the radical Republicans, led by figures such as Thaddeus Stevens and Charles Sumner, pushed for a more aggressive approach to reconstruction and sought to implement laws that aimed to protect the rights of newly freed African Americans and ensure their full citizenship and participation in society. Key legislation enacted during this era included the Civil Rights Act of 1866, the 14th Amendment, and the Reconstruction Acts of 1867.
