Which is the correct definition of the post civil war term carpetbagger?

A Derogatory term for a northerner moving to the southern states during the reconstruction era (1863-1877)

Explanation:

carpetbagger was a derogatory term applied by former Confederates to any person from the Northern United States who came to the Southern states after the American Civil War; they were perceived as exploiting the local populace. The term broadly included both individuals who sought to promote Republican politics (which included the right of African Americans to vote and hold office), and those individuals who saw business and political opportunities because of the chaotic state of the local economies following the war. In practice, the term carpetbagger was often applied to any Northerner who was present in the South during the Reconstruction Era (1863–1877). The term is closely associated with "scalawag", a similarly pejorative word used to describe native White southerners who supported the Republican Party-led Reconstruction
