In United States history, scalawags were southern whites who supported Reconstruction and the Republican Party, after the American Civil War.
Like the similar term "carpetbagger," the word has a long history of use as a slur in Southern partisan debates. The opponents of the scalawags claimed they were disloyal to traditional values of white supremacy. The term is commonly used in historical studies as a neutral descriptor of Southern white Republicans, although some historians have discarded the term due to its history of pejorative connotations.
The term is a derogatory epithet, yet it is used by many historians anyway, as in Wiggins (1991), Baggett (2003), Rubin (2006) and Wetta (2012). The word scalawag, originally referring to low-grade farm animals, was adopted by their opponents to refer to Southern whites who formed a Republican coalition with black freedmen and Northern newcomers (called carpetbaggers) to take control of their state and local governments. Among the earliest uses in this new meaning were references in Alabama and Georgia newspapers in the summer of 1867, first referring to all southern Republicans, then later restricting it to only white ones.
Historian Ted Tunnel writes that
Reference works such as Joseph E. Worcester's 1860 Dictionary of the English Language defined scalawag as "A low worthless fellow; a scapegrace." Scalawag was also a word for low-grade farm animals. In early 1868 a Mississippi editor observed that scalawag "has been used from time immemorial to designate inferior milch cows in the cattle markets of Virginia and Kentucky." That June the Richmond Enquirer concurred; scalawag had heretofore "applied to all of the mean, lean, mangy, hidebound skiny [sic], worthless cattle in every particular drove." Only in recent months, the Richmond paper remarked, had the term taken on political meaning.
During the 1868–69 session of Judge "Greasy" Sam Watts' court in Haywood County, North Carolina, Dr. William Closs, D.D. testified that a scalawag was "a Native born Southern white man who says he is no better than a negro and tells the truth when he says it." Some accounts record his testimony as "a native Southern white man, who says that a negro is as good as he is, and tells the truth when he says so."
