In U.S. history, the Reconstruction (1863-1877) was the period that followed the Amerian Civil War and during which important social changes and changes in civil rights occurred; indeed during the Reconstruction rights were guaranteed to free slaves and those states that had belonged to the Confederacy were integrated again. However, these changes were still opposed by some, especially by those that lived in the south and wanted to preserved the traditions and white supremacy that existed before the Civil War and because of this the Redeemers were created which refer to a coalition of those white southerners that oppose the changes of the Reconstruction and aimed at getting power and continue with the white supremacy stopping the changes of the Reconstruction, also they oppose the carpetbagger and scalawags that supported the Reconstruction. Therefore, the term used to refer to the southerners that tired to overturn the changes of the Reconstruction was Redeemers.
The Red Scare from WWI was the widespread fear of far-left extrematism.
The Red Scare from WWII was more extreme. Many of the accused were blacklisted or lost their jobs, although most did not in fact belong to the Communist Party.
