Final answer:
Northerners who moved to the South during Reconstruction were derogatorily called carpetbaggers by Southerners. Scalawags were Southern Whites who supported Reconstruction, while redeemers were those who wanted to end it and revert to the old social order.
Step-by-step explanation:
Northerners who moved to the South during Reconstruction were called carpetbaggers. This term was used derogatorily by Southerners to describe northerners who they believed came to the South to gain wealth through political power at the expense of Southerners.
Scalawags, on the other hand, were White Southerners who supported Reconstruction and cooperated with carpetbaggers and were often seen as traitors by others in the South.
The term redeemers was used for Southern Whites who sought to end Reconstruction and restore pre-Civil War social order.
